1 CS 400 Fire Control System The CS 400 fire control system is a programmable system for fire detection and suppression. Thanks to its configuration modularity and to the programming ease and versatility of intervention rules for the different control system events and statuses, the use of this control system is suitable for various alarm control and discharge activation functions. The control system is equipped with an operator panel composed by a keypad and a backlit alphanumeric display for the on-site system programming and configuration. By saving settings and event rules to the non-volatile memory, you can switch off the control system keeping the configuration setup unchanged. The CS 400 fire control system programming is based on the CONTROL-BY-EVENT (CBE) logic, that is, the activation control depends on the events. The control system manages a series of events (faults, alarms, prealarms) and statuses (test, line disabling, warning signals, input activation), which can be remote or coming from the control system modules. Programming is achieved by linking an event set to logical operators and by associating the obtained equation with output activation or discharge commands. With the CBE logic, programming the CS 400 control system is intuitive and easily accessible. Instead of on-site programming, the operator can use monitoring and supervision systems (Scope400, virtual oscilloscope for monitoring gas detection lines) and programming systems (Win400), saving time during management and intervention on the system. Two serial ports (RS232 and opto-isolated RS485) allow you to use remote warning devices (such as displays, printers, etc.) or modbus devices (such as Plc etc.). The CS 400 fire control system can be connetted to Ethernet network with TCP/IP protocol. You can have various feeders with redundancy function, assuring efficiency and reliable operation in every condition.

1.1 General Features • Microprocessor technology. • Control system hardware self-check. • Operator panel composed by a 20-key membrane keypad and a 40-character backlit alphanumeric

display (2 lines X 20 characters). • RS232 serial port and opto-isolated RS485 port management for remote device communications. • Modbus RTU protocol. • Ethernet link with TCP/IP protocol. • System parameterization, remote programming and runtime software update capabilities. • Visual warning signals about every single board status with details on alphanumeric display. • Control system event and status log. • Signaling and system management in line with European EN 54-2 provisions. • Feeder redundancy option. • Feeder in line with European EN 54-4 provisions. • Modular mounting of boards in 19’’ racks with locking screws.

1.3 M402 CPU The M402 CPU module is the central unit of the CS 400 fire control system. The board is equipped with a CPU and with volatile memory and Flash memory (retentive memory). The processor is the master of the control system modules (slaves): with proprietary protocol it queries the slave modules, reading their status and settings, sends general and addressed commands, implements the configurations and the system parameters, processes the programming logics, saves the system parameterization, stores the events and performs the control self-check. In addition, the CPU manages the operator panel (keypad and display), the two control system communication ports (RS232-RS485) for remote warning and monitoring devices. In addition, on the module front panel there are 3 buttons useful to perform: event ACKNOWLEDGEMENT and alarm status RESET at access level 2, LAMP TEST. These commands can also be remotely sent through opto-isolated inputs, and there are other two inputs for SOUNDER SILENCING and aut/man discharge setting. The board is equipped with relay outputs for the buzzer and for alarm, prealarm and general fault signaling. Normally, the fault relay is activated, creating thereby a “Fail Safe” logic.

1.3.1 General Features • Microprocessor technology. • Volatile and Flash memory devices on the module. • Module hardware self-check. • Operator panel management. • Internal bus communication management with proprietary protocol. • RS232 serial port and opto-isolated RS485 port management. • Modbus RTU protocol. • Ethernet link with TCP/IP protocol. • Runtime operation software update. • Event and status log management. • ACKNOWLEDGEMENT and RESET commands at access level 2, LAMP TEST from front panel and remotely. • Opto-isolated inputs for SILENCING commands and AUT/MAN settings. • General relay outputs for fault, prealarm and alarm, with NO or NC setting option. • Visual warning signals about the status of the module. • Mounting in 19’’ racks with locking screws.

1.4 M401 Module The M401 module is the feeder of the CS 400 fire control system. The feeder has been designed to assure the highest security and reliability in the power supply of the internal control system and of the external devices. In case of main supply failure or overload, an electronic switch turns on the batteries avoiding undesired stabilized voltage drop. The control system hardware architecture allows the creation of redundant systems: once one feeder fails, it is disabled and its load is maintained by the other existent feeders, without having necessarily to switch to the batteries. The failed feeder can be removed from the rack and replaced without altering the normal system operation. The M401 module checks the presence of batteries and performs a periodic battery level test. The charge circuit allows to recharge hermetic lead batteries and supplies a steady maintenance voltage to preserve their status at best. The feeders of the racks following the first are identified as M401S.

1.4.1 General Features • Microprocessor technology. • Module coding through dip-switch on board. • 24V stabilized voltage adjustable for the internal power supply of the control system. • 27.6V adjustable stabilized voltage for the battery charger. • 27V rectified filtered voltage for connected devices power supply. • Power and battery level check (signaling for undervoltage and overvoltage). • Short circuit and battery inversion protections. • Periodic battery level test. • Redundant systems options. • Visual warning signals about the status of the module. • Mounting in 19’’ racks with locking screws.

1.4.2 Visual Warning Signals On the module front panel there are LEDs for status or fault signaling. However, all module events are shown on the operator panel display.

Unless otherwise noted, visual warning signals follow ISA 1B sequences for fault signals and ISA 2C for alarm signals.

LED (Color) DESCRIPTION

MAIN SUPPLY (Green) Main supply presence LED: on and steady if main supply voltage is present.

EMERGENCY 24VDC (Green) Battery activation LED: on and steady when batteries are switched on.

FEEDER FAULT (Yellow) Feeder fault LED: it indicates an incorrect stabilized power level (undervoltage or overvoltage). Should the feeder fail, it is turned off: if there are no auxiliary feeders, the batteries of the control system are switched on. Undervoltage level is set at 21V, overvoltage at 28V.

BATTERY FAULT (Yellow) Battery absence LED: it indicates that the batteries have been disconnected or wrongly connected.

BATTERY DISCHARGE (Yellow) Low battery LED: it indicates that the battery level is below the 22V security threshold.

CHARGER FAULT (Yellow) Battery charger fault LED: it indicates an incorrect battery charger level (undervoltage or overvoltage). Undervoltage level is set at 22V, overvoltage at 28.5V. In case of overvoltage, the charge circuit is disabled.

1.4.3 Basic Configuration On the M401 module there are two dip-switches indicated as “Code” and “Setting” for the identification and the basic configuration (default). The “Code” dip-switch encodes the module ID in binary format (§ APPENDIX A). You can encode up to 31 different IDs by using the switches 1-5 (the switch 6 is not used). Every M401 module in the control system must be unique to be acknowledged by the central unit, that is, you cannot have different modules with the same ID. Otherwise, the control system activates an invalid module addressing fault (cf § 4.2 Fault Signals).

Job No.

Doc. No.


The “Setting” dip-switch sets some specific functions, listed below. From the operator panel, you can reconfigure the module (cf § 3.2.1.2 Configuring The M401 Module ).

Switch Function Description

1 Main feeder It sets the module as main feeder. If the M401 module is in the first control system rack, set the field to ON, otherwise set it to OFF.

2 Automatic battery test activation It enables the automatic battery test. If you do not want the battery test to be automatically performed every week, set this field to OFF.

WARNING: disabling this switch does not affect the manual control.

3 Main supply failure fault It activates the general fault relay of the M402 CPU in case of main supply failure. If you want a main supply failure warning on the fault relay output to terminals 3-4 of the M402 CPU, set this field to ON.

WARNING: the main supply failure warning is managed by the control system as level 2 warning (cf § 4.3 Warning Signals), regardless of the field setting.

1.5 M404 Module The M404 module is designed for automatic putting off. Through programming, it can be combined with detection modules (M406 and M407). You can have a double-consent combination with M406 (higher intervention security), or programming can be combined to a wired control within the control system. When the activation command is remotely generated, the M404 module can also be used separately. Through a selector you can set automatic or manual discharge intervention. In automatic mode, discharge is activated when the module detects the corresponding command, in manual mode it is activated only when the operator executes a command via remote buttons or local buttons on the control system. Moreover, the M404 module is set to inhibit discharge, that is, to stop timing before the solenoid valve is activated. All discharge activation or control lines are monitored.

1.5.1 General Features • Microprocessor technology. • Module coding through dip-switch on board. • Line check for opening and short circuit. • Automatic/manual mode selector. • Discharge inhibition input. • Double-consent discharge activation options. • Visual warning signals about the status of the board. • Mounting in 19’’ racks with locking screws.

1.5.3 Basic Configuration On the M404 module there are three dip-switches indicated as “Code”, “Setting” and “Timer” for the identification and the configuration. The “Code” dip-switch encodes the module ID in binary format (§ APPENDIX A). You can encode up to 63 different IDs. Every M404 module in the control system must be unique to be acknowledged by the central unit, that is, you cannot have different modules with the same ID. Otherwise, the control system activates an invalid module addressing fault (cf § 4.2 Fault Signals). The “Setting” dip-switch sets some specific functions, listed below; the “Timer” dip-switch sets the timing preceding the solenoid valve activation. From the operator panel, you can reconfigure the module (cf § 3.2.2.2 Configuring The M404 Module ). Setting:


1 Low pressure switch presence It sets the low pressure switch presence. Select ON if the discharge module has an associated low pressure switch, otherwise select OFF.

2 High pressure switch presence It sets the high pressure switch presence. Select ON if the discharge module has an associated high pressure switch, otherwise select OFF.

3 Low pressure switch line check It enables the low pressure switch line check. If you want the line to be steadily checked, set it to ON, otherwise set it to OFF.

4 High pressure switch line check It enables the high pressure switch line check. If you want the line to be steadily checked, set it to ON, otherwise set it to OFF.

5 NC contact for low pressure switch

It sets the contact type for the low pressure switch. If the low pressure switch is activated by opening the circuit (NC) set it to ON, otherwise if it is activated by closing the line (NO) set it to OFF.

6 NC contact for high pressure switch

It sets the contact type for the high pressure switch. If the high pressure switch is activated by opening the circuit (NC) set it to ON, otherwise if it is activated by closing the line (NO) set it to OFF.

7 Discharge from M406 command It sets the command type that activates the discharge. If an internal control system cabling coming from the M406 module is connected to the terminal #7 of the M404 module, set it to ON. Otherwise, set it to OFF.

8 Discharge inhibition line check It enables the discharge inhibition line check. If you want the line to be steadily checked, set it to ON, otherwise set it to OFF.

1.6 M405 Module The M405 module is set to manage 6 controlled lines of commands. Its uses vary from automatic putting off to other functions that need line status monitoring. You can separately configure the lines from the operator panel of the CS 400 control system. For each line, you can set the control mode (inversion or current), or disable control: in this case it is possible to select the quiescent state for the line (normally active or inactive). Line activation is performed through logical equations programming.

1.6.1 General Features • Microprocessor technology. • Module coding through dip-switch on board. • Line continuity check. • Operator panel-configurable lines (inversion or current control, intermittence, disabling, activation

signaling). • Unchecked line quiescent state setting option. • Event and status logics programmable for every line. • Visual warning signals about the status of the module. • Mounting in 19’’ racks with locking screws.

1.6.2 Visual Warning Signals On the module front panel there are LEDs for activation status and fault signaling. However, all module events are shown on the operator panel display.

Otherwise, the control system activates an invalid module addressing fault (cf § 4.2 Fault Signals). On the module there is a pair of jumper for each line to be set with reference to the line configuration. By default, the module lines have disabled control and activated relay. The activation is not intermittent and is not shown on the display. From the operator panel, you can reconfigure the module (cf § 3.2.3.2 Configuring The M405 Module Line ).

1.7 M406 Module The M406 module is designed for fire detection: it manages 2 non-addressed analog lines, checking their current level, signaling faults (in case of short circuit or opening) and signaling the detector intervention (alarm condition). From the operator panel of the CS 400 control system you can separately configure the 2 lines, setting alarm level, single or crossed line operation, output activation or inhibition during test. By setting the crossed lines option, the intervention of one line generates a prealarm condition, while the intervention of both lines generates the alarm condition. By setting the inhibition during test, you can perform the line test procedure without activating the tested line outputs and the discharge commands, keeping the visual warning signals active. The test is automatically completed and the outputs are reactivated if, during its execution, the M406 module reports the effective intervention of a fire alarm detector. By using the front switch, you can separately disable the lines.

1.7.1 General Features • Microprocessor technology. • Module coding through dip-switch on board. • Line check for opening/short circuit/detector intervention. • Lines can be separately configured from the operator panel. • Single or crossed line control mode. • Settable alarm level. • Line disabling from front switch option. • Line test execution from front button with output inhibition option. • Out of service/fault, alarm, discharge outputs. • Visual warning signals about the status of the module. • Mounting in 19’’ racks with locking screws.

1.8 M407 Module The M407 module is designed for fire detection: it manages 6 non-addressed analog lines, checking their current level, signaling faults (in case of short circuit or opening) and signaling the detector intervention (alarm condition). From the operator panel of the CS 400 control system you can separately configure the lines, setting prealarm/alarm level, line disabling, single or crossed line operation, single or double intervention. By setting the crossed lines option, the intervention of one line generates a prealarm condition, while the intervention of both lines generates the alarm condition. The double intervention implies that the M407 module verifies the line intervention condition (for higher detection security): when an intervention condition is detected, the line is temporarily reset. When a set amount of time has elapsed, should the intervention persist, the alarm state is signaled. You can also configure lines to manage the corresponding intervention as a simple warning or fault event.

1.8.1 General Features • Microprocessor technology. • Module coding through dip-switch on board. • Line check for opening/short circuit/detector intervention. • Lines can be separately configured from the operator panel. • Single or double intervention, single or crossed line control mode. • Settable prealarm and alarm level. • Line disabling option. • Alarm event can be configured and managed as simple warning or fault. • Visual warning signals about the status of the module. • Mounting in 19’’ racks with locking screws.

1.8.3 Basic Configuration On the M407 module there is a dip-switch indicated as “Code” for module identification. The “Code” dip-switch encodes the module ID in binary format (§ APPENDIX A). You can encode up to 63 different IDs. Every M407 module in the control system must be unique to be acknowledged by the central unit, that is, you cannot have different modules with the same ID. Otherwise, the control system activates an invalid module addressing fault (cf § 4.2 Fault Signals). By default, lines are disabled. From the operator panel, you can reconfigure the module (cf § 3.2.5.2 Configuring The M407 Module Line ).

1.9 M408 Module The M408 is designed to control non-addressed gas detectors with standard output 4-20mA and is set to use 3 or 4-wire detectors. On the front panel there is a 3-digit display where you can read line reading value in real time and a 20-LED bar showing the measurement percentage. Detection line and measurement can be easily configured from the operator panel of the CS 400 control system. Specifically, the operator can select: measurement range (ppm, % LEL, oxigen), mA view, prealarm, alarm and fault level, ascending or descending alarms, present and maximum sampled value view. From the operator panel you can also activate an automatic procedure for the module zero calibration, in order to avoid intervention with mechanical adjustments on the module. Besides, the M402 CPU is set to acquire and keep values sampled by M408 modules, providing users with a virtual oscilloscope for each gas detection line. The M408 is equipped with a current repetition line (4-20mA) for remote devices with fault, prealarm and alarm outputs.

1.9.1 General Features • Microprocessor technology. • Module coding through dip-switch on board. • Set to use 3 or 4-wire detectors. • Gas line monitoring for opening/short circuit/threshold overflow. • Line and measurement settings are configurable from the operator panel. • Reading range settings from operator panel. • Settable prealarm and alarm level and trigger. • Threshold overflow managed as alarm events or simple warnings. • Measurement maximum view. • Range or mA view. • Self-zero calibration from operator panel. • Line disabling from operator panel option. • Current repetition in 4-20mA range and fault, prealarm and alarm outputs. • Visual warning signals about the status of the module and of line measurements. • Virtual oscilloscope. • Mounting in 19’’ racks with locking screws.

1.9.2 Visual Warning Signals On the module front panel there are LEDs for alarm and fault signaling, a 3-digit display and a 20-LED bar. However, all module events are shown on the operator panel display.

The 3-digit display shows line measurement in the set reading field. It might also show the current level in mA. During startup, until the module has been acknowledged by the central unit, the display shows “8 8 8 “, then the line value. In case of a disabled line, the characters “- - - “ are displayed. The 20-LED bar shows the line reading percentage. It might also show the maximum sampled value. When you start the control system, warnings are inhibited for 45 seconds, in order to allow the stabilization of the line current. Unless otherwise noted, visual warning signals follow ISA 1B sequences for fault signals and ISA 2C for alarm signals.


PREALARM (Red) Gas line prealarm LED. The measured values exceed the set prealarm level.

ALARM (Red) Gas line alarm LED. The measured values exceed the set alarm level.

FAULT (Yellow) Gas line opening or short circuit fault LED. On and steady if the line is out of service. The opening current level is programmable (by default, it is 3.6mA), the short circuit current level is set to 30mA.

1.9.3 Basic Configuration On the M408 module there are two dip-switches indicated as “Code” and “Setting” for the identification and the basic configuration (default). The “Code” dip-switch encodes the module ID in binary format (§ APPENDIX A). You can encode up to 63 different IDs. Every M408 module in the control system must be unique to be acknowledged by the central unit, that is, you cannot have different modules with the same ID. Otherwise, the control system activates an invalid module addressing fault (cf § 4.2 Fault Signals). The “Setting” dip-switch sets some specific functions, listed below. From the operator panel, you can reconfigure the module (cf § 3.2.6.2 Configuring The M408 Module ).

2.9 Remote Device Connection The CS 400 fire control system is equipped with two serial ports on the M400RS module: one RS-232 port on the DSUB-9 connector and one RS-485 port on the screw terminals identified as A and B. RS232 Serial The control system transmits data on the connector pin 2 and receives data on the pin 3. To connect any device using the EIA RS-232C V.28 standard (for 9-pole connector), for example Personal Computer, you need a 9-pole pin-to-pin serial cable. You should pay more attention when using a 25-pole connector device, since for this type of connector the standard provides for transmission on pin 2 and receiving on pin 3. The following are summary tables useful for connection.

2.10 Startup Actions At startup, the CS 400 fire control system checks the hardware devices on the M402 CPU and the system program by which the control unit can operate. At this stage, the display is on and signals the system check; it also indicates the firmware revision running at loading stage.

After the check is completed, the central unit performs one of the following procedures:

• Configuration, if system parameters are valid. • Initialization, if system parameter are absent or invalid.

Configuration The last system configuration saved is loaded and the existent modules are configured.

When the procedure is completed, if the module fault LEDs are still blinking, it means that the module has not been acknowledged as belonging to the loaded configuration. These are the possible causes:

• The module is new to the loaded configuration (that is, it was introduced after the last configuration saving).

• The module is faulty. Please refer to Chapter 3 (cf § 3.6 Updating The System ) to update the system with the new module. Initialization If the control system has no valid system configuration, a self-configuration stage is performed. The central unit acknowledges the existent modules and takes as configuration the default values set with the corresponding dip-switch on the modules.

During self-configuration, the fault LEDs of each module blink until the central unit acknowledges the module. When the procedure is completed, if the module fault LEDs are still blinking, it means that the module has not been initialized. These are the possible causes:

• There are two modules of the same type with the same ID. • The module is faulty.

In this case, remove the module from the control system and make sure its ID is unique, that is, there are no modules of the same type with the same ID. Please refer to Chapter 3 (cf § 3.6 Updating The System ) to have the module acknowledged by the control system. When the startup stage is completed, if there are no events to signal, the display goes off and the following screen is shown:

3 Control System Programming and Management This section describes the CS 400 control system configuration and programming procedures. In order to easily access the different functions and as a reference summary, at the beginning of each paragraph, you are provided with a table describing all the commands by which you can access the desired functions (function-specific commands appear in bold). Nonetheless, to those who are programming the control system for the first time, it is recommended to carefully read the command and view screen descriptions. To access programming and management menus, press the Prog key: the display turns on and you see the Menu List screen containing the system management options, basically aimed at the operator user, and the programming options, aimed at the installer and at the operator qualified for system configuration. You can access the Menu List screen only if all alarm statuses and active faults have been acknowledged.

Press Esc to return to the normal operation screen: if you changed the control system configuration, you are prompted to save changes so that the new programming is available at the next control system startup.

3.1 Control System Programming Quick access command summary:

Action Displayed items Press Prog Menu List Press 3 Lev 3 password entry Type a five-digit password --- Press Enter Programming Menu

You can access the control system programming through two different modes, based on the configuration change rights: • Read-Write mode: access granted to the operator qualified for system configuration. • Read Only mode: access granted to user for programming reference only. Read-Write Mode In this mode you can configure modules and the central unit, program logics, save parameters, etc. To access the programming from the Menu List screen, press 3 and then enter the level 3 password to access the Programming Menu.

Type the 5-digit password and press Enter (by default, the password is: 33333). If the password is correct, the Programming Menu will appear. If the password is wrong, you will see an error message with an alphanumeric code: press Esc to perform a new entry. In case you forgot the password, you can notify the displayed password-decoding code to the manufacturer. Pressing Esc you abort the programming access action. In the Read-Write mode, the event warning signals on the display are inhibited, except for those related to the ACKNOWLEDGEMENT, SILENCING, RESET, and LAMP TEST commands. An alarm or fault status during programming does not imply the automatic exit from the corresponding menus. Read Only Mode In this mode you cannot perform control system configuration changes. All actions and keys related to operation parameter changes are inhibited: you can only check the existing configuration. Should an alarm or

3.2.6.3 Zero Self-Calibration The zero self-calibration procedure allows you to automatically calibrate the zero value of the line measurements, without having to perform any mechanical adjustments (ex.: trimmer adjustments) on the module. To perform the calibration: From the Calibration page of the M408 Configuration Menu set the Z Calib field to ENA and press Enter. In this way you activate an automatic procedure that allows you to correct the zero value of the measurement according to the existing current value on the sensor line. By setting the field to RST, you delete any zero adjustment and set the module back to the default calibration. If you don’t wish to enable any correction, set the field value to DIS. Calibration actions generate a level 4 warning event that is archived, if you enabled the history log (cf § 4.3 Warning Signals). WARNING: Before performing the self-calibration, please make sure that the line current value is steady

and that the sensor has been correctly calibrated.

Type a five-digit password --- Press Enter Programming Menu Press 3 Self-Configuration Procedure

With the Self-Configuration procedure you can update the system configuration based on the modules contained in the control system. This procedure allows the M402 CPU to query the current modules without changing the pre-existing module configuration and programming, to delete the no longer existing modules and to add any new module to the configuration. In the following example you see the two most common actions of the system update procedure: a module deletion and the creation of a new module. A module deletion from the control system generates a fault event because the control system attempts to communicate with the removed module. If, for example, you remove a M408 module with an ID of 2, you’ll see the following display:

Access the Programming Menu and press 3 to start the updating process. During the updating phase (it takes a few seconds) you receive the following message:

At the end of the updating process, the Programming Menu screen is displayed and the fault event is automatically deleted. Now the system is configured without the removed M408 module. When you add a new module, the module fault LEDs start blinking. This means that the module has not been acknowledged by the control system yet and therefore it is inactive. To add the module to the system, perform the above updating process. The fault LEDs stop blinking and the configuration set with the dip-switch on the module is automatically applied. At this point the operator can start the new module configuration and programming (cf § 3.2 Module Programming). This action generates a level 2 warning event that is archived, if you enabled the history log (cf § 4.3 Warning Signals).

The Reset option allows you to perform a M402 CPU restart without turning off the system. When you perform a reset, only the signaling status of the control system is changed, this means that the enabling/signaling status of various modules and the power supply of remote and connected devices remain unchanged. Use the Init command to delete the configuration of the control system from the non-volatile memory. If you manually turn off the control system, at the restart of the a system an initialization will be performed (cf § 2.10 Startup Actions) and the default configuration will be set. This action generates a level 2 warning event that is stored only if you enabled the history log (cf § 4.3

4 Events The CS 400 fire control system can handle a set of events originated by external modules and remote devices in order to monitor the system, the alarm or fault signals, and the activation of fire suppression functions.

4.1 Normal Operation When no system alarms or faults are present, the display shows the following message:

The first line displays the system name (Cf § 3.3.2 Setting The System Name ) and current time, while the second line shows the normal operation message and current date. During normal operation, the M402 CPU central unit performs the following functions:

• Periodically polls the available module to check their status and verify if valid responses are received.

• Checks the presence of the battery every 15 seconds. • Manages the remote devices. • Manages the operator panel. • Runs the self-diagnostic procedure every 30 minutes, to verify the operation and integrity of memory

units. In case of alarm and/or fault events, or in the event of a simple warning, the control system displays the related message. Events can be displayed automatically or manually depending on the setting used during system programming (Cf § 3.8.2 Configuring The Events ). In automatic mode, all active events are displayed sequentially in 5 seconds intervals. In manual mode, the last event (chronologically) is shown: the operator can scroll the list of all events by pressing the ← (Left) and → (Right) keys. The only exception to this rule are the warning events controlled by a timer and related to the ACKNOWLEDGEMENT, SILENCING, RESET and LAMP TEST commands, which are actuated by buttons located on the front panel of the control system; these events are always displayed automatically.

4.1 Alarm Signals In case of alarm, the display lights up to display the detected event, while the system activates the prealarm and/or general alarm relay, and the prealarm and/or alarm LEDs on the front panel of the M402 CPU start to blink; also, the system activates the visual warning signals and outputs related to the modules which detected the alarm. The buzzer starts to sound continuously. If logging is enabled (Cf § 3.8.2 Configuring The Events ), the alarm is recorded in the event log. During the ACKNOWLEDGEMENT, the blinking alarm and/or prealarm LEDs turn steady, while the buzzer stops sounding. The event signal remains on the display until the RESET command is issued; this turns off the display and the prealarm/alarm LEDs on the central unit and on the modules that detected the event, disables the prealarm and/or general alarm relay, and turns off the outputs of the modules in alarm status. WARNING: to activate the RESET command, run the ACKNOWLEDGEMENT command first: any

attempt to reset the alarm status will not be recognized and will be ignored by the central unit. The alarm event signal remains until the RESET command is issued, even if the event is no longer present.

A typical alarm event signal may look as follows:

The left side shows the module or the line that detected the alarm. The first line displays the alarm type, while the second shows the name associated to the module or line. The acknowledgement of the shown alarm event appears in the top right corner. By pressing Enter, you can access detailed information about the event (Cf § 4.6.1 Event Lists And Information).

Alarm Message Module Description

DISCHARGE ACTIVATE M404 It indicates the activation of the discharge command and the beginning of the time control which sets the solenoid valve activation command.

M404 DISCHARGE CMD-MANUAL SETTING

It indicates that the discharge command is active, although temporarily interrupted because the module is operating manually. To activate the discharge, change the module setting to AUT mode or press the related buttons.

M404 DISCHARGE SYSTEM ACTIVATE

It indicates that the system high pressure switch was activated and the discharge has terminated.

M406 PREALARM TESTING It indicates that one crossed module line activated the alarm due to the test.

LINE PREALARM M406 M407

It indicates that one crossed module line activated the alarm.

LINE ALARM M406 M407

It indicates that one single module line activated the alarm.

4.2 Fault Signals In case of failure, the display turns on to show the event, the general fault relay is activated, the fault led on the front panel of the M402 CPU starts to blink, and the related visual warning signals and outputs of the fault modules are activated. The buzzer starts to play intermittently. If archiving is enabled (Cf § 3.8.2 Configuring The Events ), the fault is recorded in the log. During the acknowledgement, the blinking fault LEDs turn on and steady, while the buzzer silences. After the acknowledgement, the fault signal remains on until the fault reason is removed: Once the problem is solved, the control system returns to normal operation: the display turns off, and all fault signals are disabled on the central unit and on the modules involved in the event. WARNING: the RESET command has no influence on how the fault event is handled. The following shows a typical fault signal:

The module or module line which detected the fault is displayed at left. The first line shows the type of fault, while the second shows the name associated to the module or line.

Fault Message Module Description

CHARGER UNDER VOLTAGE FAULT

M401 It indicates a battery voltage too low, set to 22V. In this case, it means that the batteries are not properly recharged. Execute the acknowledgment; should the fault persist, verify batteries’ integrity: if batteries present any error, the high current absorption activates the recharging circuit protection. Alternatively, replace the main M401 module.

WARNING: if you work with a single rack control system, turn off the control system before replacing it. Working with multiple rack control systems, redundancy of power supply modules allows replacing the control system during operation.

CHARGER OVER VOLTAGE FAULT

M401 It indicates a battery voltage too high, with the risk of damaging them. The level is set to 28.5V: in case of fault, the recharging circuit is disabled. Execute the acknowledgment; should the fault persist, replace the main M401 module.


UNDER VOLTAGE FAULT M401 It indicates that the stabilized voltage generated by the supply module (either main or secondary) is below the security level, set to 21V. Verify that no device is fed by stabilized voltage (connected to terminals 5 and 6), thus generating a high current absorption (3 Amps) and causing the activation of the protection status for supply modules. Alternatively, replace the damaged M401 module.


OVER VOLTAGE FAULT M401 It indicates that the stabilized voltage generated by the supply module (either main or secondary) is above the security level, set to 28V, with the risk of damaging the control system modules. The damaged power supply unit is disconnected: if no other power supply units are available, the batteries of the control system are switched on. Execute the acknowledgment; should the fault persist, replace the damaged M401 module.

WARNING: if you work with a single rack control system, turn off the control system before replacing it. Working with multiple rack control systems, redundancy of power supply allows replacing the control system during operation.

MISSING BATTERY FAULT M401 It indicates that the auxiliary power supplied by batteries is not present due to absence, short circuit or inversion of connections. Verify the connections of the batteries.

LOW PRESSURE FAULT M404 It indicates that the high pressure switch was activated due to system low pressure. Verify the pressure of the system shut off circuit.

• Dynamic fault • Static fault

A dynamic fault occurs when the system detects an error running a program, or if there are damaged execution data. A static fault occurs when the system detects an error due to damaged retentive data, or a problem with the flash memory data loaded during the control system start up. If the error is a “dynamic fault”, the M402 CPU runs an automatic reset in order to restore the correct content of system memory or to restore the running program. During the reset, the activation and warning status of the available modules is not modified, and the level of power supply to connected devices is maintained.

Execution data corruption Central system parameters corruption Programmed logic corruption Running program code corruption Interrupted communications with modules (watchdog polling) Interrupted main program execution (watchdog main) Internal processor error on M402 CPU (stack overflow) Internal processor error on M402 CPU (stack underflow) Illegal memory access on M402 CPU (access fault)

During the restart, the event is recorded in the fault list, and the “disabled” status is set. The fault is recorded in the log, and a SYSTEM INTEGRITY ERROR is reported; this condition persists even after the acknowledgment, forcing the operator to reset the central unit to eliminate it (Cf § 3.8.10 Deletion Of a System Fault). If the error is a “static fault”, a system fault is generated, indicating which procedure to run in order to eliminate it. This category consists of the following types of fault:

The CS 400 fire control system is designed to send the operating status to remote printing devices or to print internally (“Status Print” mode): a print command is issued every time the normal status changes, for example due to an alarm, fault, command and outputs activation, allowing to save detailed information about the event on paper. To enable the “Print Status” mode, press the List and 2 keys to access the Print Menu. From the Print Menu, press 1 to activate the “Status Print” mode. Then, you must enter a filter to apply to the printable events; the following table lists the filter values:


Filter NUL / A / F / AF / W / AW / FW / AFW

It sets the filter to apply to printed events. A = alarms and prealarms only F = faults only AF = alarms and faults W = warnings only AW = alarms and warnings FW = faults and warnings AFW = all events WARNING: entering the NUL value in the field, the printer enters the “Waiting to Print” mode, does not record the current control system events, and waits for other printing commands (for example, archive or programming printing).

During the activation of the “Status Print” mode, the system prints a 40 column report with an header and the list of active events, updated as new events occur. The report header contains the system name and serial number, the type of recorded events and the activation date/time of the “Status Print” mode. Each event is reported in a separate section containing the following information: event name, module or generating line name, detailed event information (Cf § 4.6.1 Event Lists And Information). The “Status Print” mode is disabled when:

• You disable the printer (Cf § 3.8.4 Configuring The Control System For Win400 • ). • You enable the “Waiting to Print” mode (by entering the NUL value in the “Filter” field). • You activate other modes in the Print Menu.

4.6 Accessing The Event Log The CS 400 fire control system can store up to 128 events, provided the archive is enabled in the system configuration (Cf § 3.8.2 Configuring The Events ). The event log can be accessed for normal operations, as well as for alarm or fault events previously detected. To access the List Menu, press the List button. The display shows the following options:

Press Esc to exit the List Menu and return to the normal operation screen. WARNING: in case of an event warning while the lists are displayed, the system automatically exits from

event log and displays the event; when this happens, the warnings related to the ACKNOWLEDGEMENT, SILENCING, RESET and LAMP TEST commands are displayed.

5 Programming The Event Logic Programming the event logic is based on the CONTROL-BY-EVENT (CBE) logic, that is, the activation control depends on the events. The CS 400 fire control system can manage a series of events (faults, alarms, prealarms) and statuses (test, line disabling, warning signals, input activation), either coming from remote devices or from the control system modules. Programming is achieved by linking an event set (OPERANDS) with logical operators (OPERATORS), and by associating the obtained equation with output activation or discharge commands. With the CBE logic, programming the CS 400 control system is intuitive and easily accessible.

5.1 Translating An Event Into A Logic Symbol During the creation of the logic equations, each single event is uniquely defined in symbolic mode using the following format:

Type of module

ID of module

Type of event Event generator

Type of module: identifies the type of module that generated the event A = power supply unit (M401 module) C = central unit (M402 CPU) S = discharge (M404 module) O = relay-controlled outputs (M405 module) D = 2 lines detection (M406 module) R = 6 lines detection (M407 module) G = gas detection (M408 module) P = relay outputs (M409 module) ID of module: it identifies the module code (set by dip-switches on the module itself) The identifier for the M402 CPU is always 01. Type of event: it identifies the possible event type P = prealarm A = alarm G = fault W = warning T = test activation F = disabling Event generator: it identifies the element that generated the event Numeric in case of line Letter in case of device For example: S02GE = solenoid valve fault in discharge module with ID 02 Other module-generated events use the following syntax for their symbolic format:

Type of module

ID of module

Type of event G

Type of event: it identifies the possible event type A = alarm G = fault G: it identifies a general event type For example: S02GG = general fault on discharge module with ID 02

5.2 Operators And Syntax The syntax for logic programming follows strict rules that you need to respect in order to avoid errors during processing by the control system (error codes and their explanations are listed in the Appendix). A CBE equation is composed by logical operators binding single or general events (logic operands) in order to create the desired control. Basic rules to comply with are as follows:

• Each logic can contain up to 8 operators. • The maximum length of each logic is 95 characters. • The number of open parenthesis must be equal to the number of closed ones. • You can encode up to 511 different logics.

5.2.1 The NULL Operator Syntax: OP It executes the operand. The logical level returned by the operator corresponds to the operand’s level. For example: D01A1 The equation is true when line 1 of the M406 module with ID 01 is in alarm status.

Job No.

Doc. No.


5.2.2 The OR Operator Syntax: OP1+OP2 It executes the logic operator OR between two operands. The operator returns the logic value true if at least one operand is true. For example: D01A1 + D01A2 The equation is true when lines 1 or 2 of the M406 module with ID 01 are in alarm status. The operand can be a complex condition (generated by other operators): in this case, it must be enclosed in parenthesis. For example: D01A1+(D01A2*D02A1….) The equation is true when line 1 of the M406 module with ID 01 is in alarm status, or the condition in parenthesis is true.

5.2.3 The AND Operator Syntax: OP1*OP2 It executes the logic operator AND between two operands. The operator returns the logic value true if both operands are true. For example: D01A1*D01A2 The equation is true when both lines of the M406 module with ID 01 are in alarm status. The operand can be a complex condition (generated by other operators): in this case, it must be enclosed in parenthesis. For example: D01A1*(D01A2+D02A1….) The equation is true when line 1 of the M406 module with ID 01 is in alarm status, and the condition in parenthesis is true.

5.2.4 The NOT Operator Syntax: !OP It executes the negation of the operand. The operator returns a logic value opposite to the operand. For example: !D01A1 The equation is true when line 1 of the M406 module with ID 01 is not in alarm status. The operand can be a complex condition (generated by other operators): in this case, it must be enclosed in parenthesis. For example: !(D01A1+D01A2*….) The equation is true when the condition in parenthesis is false. It can be inserted in an equation along with other operators. For example: A01WB*A01GB+!D01A1

5.2.5 The LATCH Operator Syntax: lOP It executes the latch of the operand. The logic becomes true on the operand’s leading edge and remains true until a RESET command is run, regardless of the operand’s status. For example: lD01G1

Job No.

Doc. No.


The logic is activated upon the fault warning for line 1 of the M406 module with ID 01, and remains active until the reset, even if an acknowledgment cancels the fault status. The operand can be a complex condition (generated by other operators): in this case, it must be enclosed in parenthesis. For example: l(D01A1+D01A2*….) It can be inserted in an equation along with other operators. For example: A01WB*A01GB+lD01A1

5.2.6 The DELAY Operator Syntax: d(hh.mm.ss OP) It delays the activation of a logic. Before the operator returns the logic value true, the system waits hh hours, mm minutes and ss seconds from the moment the condition enters the true status. The operator remains true until the condition is true. For example: d(00.00.10 D01A1) From the moment the line 1 of the M406 module with ID 01 goes in alarm status, the system waits 10 seconds before the equation becomes true, and it remains in this logic status until the line is in alarm status. The operand can be a complex condition (generated by other operators): in this case, it must be enclosed in parenthesis. For example: d(00.00.10(D01A1+D01A2*….)) It can be inserted in an equation along with other operators. For example: A01WB*A01GB+d(00.00.00 D01A1)

5.2.7 The ELAP Operator Syntax: e(hh.mm.ss OP) Activation for a predefined time. The logic activates on the variation edge of the condition, then remains active for hh hours, mm minutes and ss seconds, even if during this time the condition returns to false status. At the end of the timing, the condition must return false in order to be able to restart the logic. For example: e(00.00.10 D01A1) The equation becomes true when line 1 of the M406 module with ID 01 goes in alarm status, and remains true for 10 seconds before becoming false, regardless of the line status. The operand can be a complex condition (generated by other operators): in this case, it must be enclosed in parenthesis. For example: e(00.00.10(D01A1+D01A2*….)) It can be inserted in an equation along with other operators. For example: A01WB*A01GB+e(00.00.00 D01A1)

5.2.8 The CAL Operator Syntax: c(dd/mm 00.00 dd/mm 00.00) c(dow 00.00 dow 00.00) c(dd/mm 00.00 dow 00.00) It executes the activation on the specified date (dd/mm field) and time (00.00 field) then deactivates on the specified date (dd/mm field) and time (00.00 field). The date field can be replaced with the week day (dow field). The first two fields indicate the beginning of the activation, while the second pair indicates the end

Dow is the day in symbolic format (SU MO TU WE TH FR SA). You can also enter a list of days using the following format: dow1.dow2.dow3... for example, (SU.WE.FR) For example: c(12.01 07.50 14.01 18.00) The equation becomes true on Jan. 12 at 7.50 a.m., then turns false on Jan. 14 at 6.00 p.m. For example: c(SU 07.50 WE 18.00) The equation becomes true every Sunday at 7.50 a.m., and turns false on the following Wednesday at 6.00 p.m. It can be inserted in an equation along with other operators. For example: A01WB*A01GB+ c(SU 07.50 WE 18.00)

5.2.9 The CMD ACK Operator Syntax: aOP It executes the ACKNOWLEDGEMENT command. When the operand changes from false to true, the system generates an ACKNOWLEDGEMENT command. For example: aD01A1 The ACKNOWLEDGEMENT command is executed when line 1 of the M406 module with ID 01 goes in alarm status. The operand can be a complex condition (generated by other operators): in this case, it must be enclosed in parenthesis. For example: a(D01A1+D01A2*….) The value returned by the operator is the logic value of its operand. It can be inserted in an equation along with other operators. For example: A01WB*A01GB+aD01A1

5.2.10 The CMD TAC Operator Syntax: tOP It executes the SILENCING command. When the operand changes from false to true, the system generates a SILENCING command. For example: tD01A1 The SILENCING command is executed when line 1 of the M406 module with ID 01 goes in alarm status. The operand can be a complex condition (generated by other operators): in this case, it must be enclosed in parenthesis. For example: t(D01A1+D01A2*….) The value returned by the operator is the logic value of its operand. It can be inserted in an equation along with other operators. For example: A01WB*A01GB+tD01A1

5.2.11 The CMD RST Operator Syntax: rOP It executes the RESET command. When the operand changes from false to true, the system generates a RESET command. For example: rD01A1 The RESET command is executed when line 1 of the M406 module with ID 01 goes in alarm status.

The operand can be a complex condition (generated by other operators): in this case, it must be enclosed in parenthesis. For example: r(D01A1+D01A2*….) The value returned by the operator is the logic value of its operand. It can be inserted in an equation along with other operators. For example: A01WB*A01GB+rD01A1

5.2.12 The SWITCH_ACK Operator Syntax: v(00.00.00) It executes the time controlled activation of the ACKNOWLEDGEMENT command. The logic activates for the predefined time each time an ACKNOWLEDGEMENT command is generated. Any ACKNOWLEDGEMENT commands run during the activation are ignored by the logic. For example: v(00.00.10) When the ACKNOWLEDGEMENT command is run, the logic becomes true for 10 seconds. It can be inserted in an equation along with other operators. For example: A01WB*A01GB+ v(00.00.10)

5.2.13 The SWITCH_TAC Operator Syntax: w(00.00.00) It executes the time controlled activation of the SILENCING command. The logic activates for the predefined time each time a SILENCING command is generated. Any SILENCING commands run during the activation are ignored by the logic. For example: w(00.00.10) When the SILENCING command is run, the logic becomes true for 10 seconds. It can be inserted in an equation along with other operators. For example: A01WB*A01GB+ w(00.00.10)

5.2.14 The SWITCH_RST Operator Syntax: z(00.00.00) It executes the time controlled activation of the RESET command. The logic activates for the predefined time each time a RESET command is generated. Any RESET commands run during the activation are ignored by the logic. For example: z(00.00.10) When the RESET command is run, the logic becomes true for 10 seconds. It can be inserted in an equation along with other operators. For example: A01WB*A01GB+ z(00.00.10)

5.2.15 The NULL_ACK Operator Syntax: pOP Cancels the logic when the ACKNOWLEDGEMENT command is run. The logic is canceled each time an ACKNOWLEDGEMENT command is generated, even if its condition is true.

Job No.

Doc. No.


For example: pD01A1 The equation is true when line 1 of the M406 module with ID 01 is in alarm status. When the ACKNOWLEDGEMENT command is run, the logic becomes false (although its condition remains true). The operand can be a complex condition (generated by other operators): in this case, it must be enclosed in parenthesis. For example: p(D01A1+D01A2*….) It can be inserted in an equation along with other operators. For example: A01WB*A01GB+pD01A1

5.2.16 The NULL_TAC Operator Syntax: qOP It cancels the logic when the SILENCING command is run. The logic is canceled each time a SILENCING command is generated, even if its condition is true. For example: qD01A1 The equation is true when line 1 of the M406 module with ID 01 is in alarm status. When the SILENCING command is run, the logic becomes false (although its condition remains true). The operand can be a complex condition (generated by other operators): in this case, it must be enclosed in parenthesis. For example: q(D01A1+D01A2*….) It can be inserted in an equation along with other operators. For example: A01WB*A01GB+qD01A1

5.2.17 The NULL_RST Operator Syntax: oOP Cancels the logic when the RESET command is run. The logic is canceled each time a RESET command is generated, even if its condition is true. For example: oD01F1 The equation is true when line 1 of the M406 module with ID 01 is excluded. When the RESET command is run, the logic becomes false (although its condition remains true). The operand can be a complex condition (generated by other operators): in this case, it must be enclosed in parenthesis. For example: o(D01A1+D01A2*….) It can be inserted in an equation along with other operators. For example: A01WB*A01GB+oD01F1

5.2.18 The XGROUP Operator Syntax: xn(list) where list: OP1/OP2/OP3…and n =1…9. It executes the activation after a predefined number of conditions. The logic is activated when at least n conditions of the listspecified are true. For example: x2(R01A1/R04A3/R05A4) The equation is true when at least 2 lines of list are in prealarm/alarm status. For example: x2(R01GG)) The equation is true when at least a total of 2 lines of the M407 module with ID 01 are in fault status. It can be inserted in an equation along with other operators. For example: A01WB*A01GB+x3(R01A1/R04A3/R05A4)

5.2.19 The TEST LED Operator Syntax: y. It executes the activation during test led command. For example : y The equation is true when test led command is executed. It can be inserted in an equation along with other operators. For example : y +(A01WB*A01GB)

5.3 System Logics System logics can be called from within the module logics. They are useful when an equation associated to a module is very complex: in this case, it can be broken into several smaller system equations, called from within the equation, to simplify programming. Another similar example occurs when more equations share a common part: in this case, you can program a logic that executes the common part and is called in several different equations, without having to write them fully. System logic follow the same syntax rules discussed in previous paragraph, and can be called from within an equation using the following syntax: For example: A01WB*L03 The equation calls the system logic with index 03, previously programmed for the purpose. If the equation 03 was not programmed, its insertion generates a syntax error. The system allows 63 different logics, with indexes from 01 to 63.

5.4 Logical Errors The following table shows the error codes which can occur programming the CBE logics. Syntax error: caused by errors in the equation’s form. Verify again the logic syntax looking at the cursor blinking over the error.

6 The Modbus RTU Protocol The CS 400 fire control system allows you to connect remote devices communicating over the serial line to the Modbus RTU protocol. For example, you can associate the control system with a PLC controlling and supervising the system inputs and outputs. The PLC reads the input and output status and enables the scheduled outputs according to specific programming logics. With the Win400 program the operator can define a series of variables that are transmitted between the remote device and the control system. For a detailed description on how to use the configuration program, please refer to Win400 manual. The followings sections provide some general “consistency” rules that you have to follow in order to avoid programming errors, that result in an incorrect operation of the communication protocol.

6.1 Programming The control system supports 256-word X 16-bit data memory, for a total of 4096 bit, to transmit write only/read only data. Data can be divided into: inputs, outputs (coil) and registers. The operator associates each variable with a control system status (“status association”), a rule (“rule association”) or a logic equation, according to the syntax for CBE logic provided in Chap. 5. You can define up to 256 rules. In addition, each variable is associated with an identifying address. The same variable type is traditionally associated with consecutive addresses, in order to avoid allocating unused memory. Addresses between 1800 and 1899 are reserved for internal use only and cannot be accessed by the user. Inputs: read-only bit variables. You can perform a status association or a rule association. Example of status association: Name R/W Type Address Bit Association Reverse Equation Description INP_1 R Input 1000 0 Status False R01G3 L3 fault status You defined a read-only input variable with descriptive name INP_1 and address 1000. This variable is associated with the line 3 fault status of the M407 module with id=01. The value you read is not reversed compared to that of the control system. Example of rule association: Name R/W Type Address Bit Association Reverse Equation Description INP_2 R Input 1001 0 Logic False R01A1*R01A2 L1-2 ALR status You defined a read-only input variable with descriptive name INP_2 and address 1001. This variable is associated with the given rule: the input is true when both lines of the M407 module with id=01 are in alarm status. The value you read is not reversed compared to that of the control system. The Bit field of input variables is always set to 0. WARNING: the setting of a write-only input type will generate a compiling error during the programming

transfer from Win400 to the control system. Outputs: read-/write-only bit variables. They can be associated only with an activation status of a physical output line for M405 and M409 modules. Example of status association: Name R/W Type Address Bit Association Reverse Equation Description OUT_1 R/W Coil 1000 0 Status False O02A3 L3 output activation

You defined a read-/write-only output variable with descriptive name OUT_1 and address 1000. This variable is associated with the line 3 activation status of the M405 module with id=02. The write mode allows you to enable the line by writing the appropriate activation command (according to the specification of the Modbus protocol). The value you read is not reversed compared to that of the control system. The Bit field of coil variables is always set to 0. WARNING: any association different from that of the activation status, will generate a compiling error

during the programming transfer from Win400 to the control system. Registers: 16 bit read-/write-only variables. Each register bit is associated with a status or a rule. Example of rule/status association: Name R/W Type Address Bit Association Reverse Equation Description REG_1 R Register 1000 0 Status False R01A1 L1 Alarm REG_1 R Register 1000 1 Status False R01A2 L2 Alarm REG_1 R Register 1000 2 Status False R01A3 L3 Alarm REG_1 R Register 1000 3 Status False R01A4 L4 Alarm REG_1 R Register 1000 4 Status False R01A5 L5 Alarm REG_1 R Register 1000 5 Status False R01A6 L6 Alarm REG_1 R Register 1000 6 Status False R01G1 L1 Fault REG_1 R Register 1000 7 Status False R01G2 L2 Fault REG_1 R Register 1000 8 Status False R01G3 L3 Fault REG_1 R Register 1000 9 Status False R01G4 L4 Fault REG_1 R Register 1000 10 Status False R01G5 L5 Fault REG_1 R Register 1000 11 Status False R01G6 L6 Fault REG_1 R Register 1000 14 Logic False R01A1*R01A2 L5-6 Alarm REG_1 R Register 1000 15 Logic False R01G1*R01G2 L5-6 Fault You defined a read-only register variable with descriptive name REG_1 and address 1000. Bits between 0 and 5 are associated with the line alarm status of the M407 module with id=01; bits 6-11 are associated with the fault status. Bits 12 and 13 are not defined. Bit 14 and 15 are associated with rules. WARNING: register bits can be write-bit only if they are associated with an activation status of a physical

output. Any other status or rule association will generate a compiling error during the programming transfer from Win400 to the control system.

Example of association of an activation status: Name R/W Type Address Bit Association Reverse Equation Description REG_2 R/W Register 1001 0 Status False O02A1 L1 Activation REG_2 R/W Register 1001 1 Status False O02A2 L2 Activation REG_2 R/W Register 1001 2 Status False O02A3 L3 Activation REG_2 R/W Register 1001 3 Status False O02A4 L4 Activation REG_2 R/W Register 1001 4 Status False O02A5 L5 Activation REG_2 R/W Register 1001 5 Status False O02A6 L6 Activation REG_2 R/W Register 1001 6 Status False P03A1 L1 Activation REG_2 R/W Register 1001 7 Status False P03A2 L2 Activation REG_2 R/W Register 1001 8 Status False P03A3 L3 Activation REG_2 R/W Register 1001 9 Status False P03A4 L4 Activation REG_2 R/W Register 1001 10 Status False P03A5 L5 Activation

REG_2 R/W Register 1001 11 Status False P03A6 L6 Activation You defined a read-only register variable with descriptive name REG_2 and address 1001. Bits between 0 and 5 are associated with the line activation status of the M405 module with id=02; bits 6-11 are associated with the line activation status of the M409 module with id=03. Writing on the register you will enable or disable the lines. Bits between 12 and 15 are not defined. Example of association “Null State” type: Nome R/W Tipo Indirizz

Bits between 0 and 15 have no association: they can be read/write from plc without modifing central unit state. WARNING: a register cannot contain both read-only and write-only bits; in this case any access to the

register will generate an error message according to the specification of the Modbus protocol. When the programming is completed, the operator must download the data in the control system using the specific command of the Win400 menu. To enable the communication with the Modbus protocol you have to activate it using the relevant configuration parameter.
