Page 2-8

Here are a few more instructions regarding the input configuration:

1. Process signals (Proc) and strain gage (DMS) sensors (LoAd)

When connecting process signals or strain gage (DMS) sensors the input signal rangemust be specified.

Process signals: There are 2 voltage ranges (0-1 V, 0-10 V) and 2 current ranges(0 - 1 mA, 0 - 20 mA).If you have selected "VOLT", 2 input ranges are offered.Select between: " 1V" for inputs 0 - 1,

"10V" for process signals 0 - 10V.The maximum voltage amounts to 10 V.However, if you have selected "AMP", you have the following ranges atyour disposal: " 1mA" for the input 0 - 1 mA,

"20mA" for the inputs 0 - 5 mA,0 - 20 mA or 4 - 20 mA.

The maximum current amounts to 20 mA.

Strain gage sensors: If the device is to be used as a DMS strain gage indicator, select one ofthe following input ranges:

"15 mV", "30 mV", "60 mV","300mV".Correct selection depends on the sensitivity of the DMS sensor. Sensorswith more than 300 mV input voltage may not be used.

Example: Characteristic value of the strain gage sensor (DMS) according

to the data sheet: 1.41 mV/V

Feed voltage (measured): 9.82 V

Signal from sensor computed at: U(mV) = 1.41 . 9.82 = 13.82

Selected input range is "15 mV".


Page 2-9

Sensor feed for senors with process signal output option can be selected using the menu.

The feed voltage can be selected in a range between 24 V and 10 V, the latter can also bereduced to 5 V using a jumper. (Jumper see figure below).If the device is used as a strain gage display, only a feed voltage between10 V and 5 V canbe selected.

JUMPER ON = FEED 5 VJUMPER OFF = FEED 10 V


Page 2-10

2. Temperature sensor

If the device is operated as a thermometer (Pt 100 or thermocouple), the linearization andrange are selected automatically in accordance with the sensor type.

You can select between 6 different thermocouples:"J", "K", "T", "R", "S" or "E".Individual temperature ranges are specified in the technical data on pages 5-8.

Temperature offset

Normally a temperature offset input is not required. This is only required if a difference existsbetween the displayed and the real temperature.

With a resolution of 0.1 ° the maximum offset is ± 9.9°, while a 1° resolution equals ± 99°.If an offset is entered the "TARE" LED lights up.During the measurement the OFFSET can be displayed at any time by pressing the MAX/MIN pushbutton.

3. Potentiometric sensors

If the device is set for potentiometric sensors (POT), the feed voltage is automatically set to10 V.As such the sensor delivers a signal of 0 - 10 V via the wiper.

2.4.4 Programming the display for the correct measurementvariables

Programming the display for the correct measurement variables

The display can be programmed from -99999 up to 99999 for process signals, strain gagesensors (LoAD) and potentiometers. The thermometers do not need any programmng as theinput and measurement range are automatically set in accordance with the sensor type selected.Here the settings can only be corrected with "Offset" (see page 2-10).

To program the measurement range you must enter 2 input values (INPUT1, INPUT2) and2 output values (DISPLY1, DISPLAY2) in accordance with the two input values. The entry isautomatically completed by the decimal point setting.

Um in das Programm-Modul 20 zu gelangen, betätigen Sie "ENTER", danach zweimal die" " -Taste.

When programming the measurement range, first the input and output parameters are enteredin accordance with point 1, then the decimal point and finally the input and output parameterscorresponding to point 2.When programming the input the decimal point is automatically set to the position which permitsthe largest possible display. However, this can be adjusted manually.

The position of the decimal point must always be selected (equally applicable to both DISPLAY1and DISPLAY2) so that the best possible resolution is attained.

The instrument provides two programming methods: SCAL and TEACH.

The SCAL mode permits the entry of 5 parameters, 2 input values (INP1, INP2), the correspondingdisplay values (DSP1, DSP2) and the position of the decimal point. This is a very precise mannerof calibrating, if the output signals of the sensors are known exactly.

In TEACH mode you need to know which signal the sensor supplies. After connecting the sensorselect the TEACH function after reaching programming routine 20 CNfdSP. After pressing theENTER button 22-tCH1- appears and the sensor needs to shed its load or supplies a zero signal.Press ENTER again and then enter the ZERO POINT POSITION. Place the decimal point at thecorrect position and confirm with ENTER. 22-tCH2- appears in the display. Now set your sensorto nominal load or the end range and confirm by pressing ENTER. Now enter the end range forthe display and finish the routine by pressing ENTER. Pressing ENTER again stores the data.

3. Controlling (HOLD, TARE, MAX/MIN, RESET)

3.1 Functions triggered via the keyboard

TARE Every time you press the "TARE" key, the value currently displayed is savedas a tare value and the display is set to zero.

To delete the tare memory, keep the "RESET" button pressed down and pressthe "TARE" key. First release the "TARE" key and then the "RESET" button.

If the device has been configured as a thermometer, this function cannot berealised. However, entering a temperature offset during input programminghas the same effect as the entering of a tare value with the "TARE" key.The "TARE" LED indicates that the device is operating with the tare value(oroffset value).Using the MAX/MIN button you can have the saved tare or offset valuedisplayed.

Disabling the It is possible to disable the "TARE" button so that the stored tare value cannotTARE function be changed. To do this disconnect the power from the device and install a

bridge between terminals 3 and 4 of the CN2 connection (see page 3-3).When the device is reconnected to power this function cannot be activated bythe keyboard.

RESET The "RESET" button is used together with the "TARE" or "MAX/MIN" buttonsto delete the memory of the Tare or Max or Min values. To do this RESET mustbe pressed at the same time as the corresponding button.

LIMIT In operating mode this button is only enabled when the device contains anoption for output control: 2 RELAYS, 4 RELAYS or 4 OPTOCOUPLERS (seepage 4-11).If you press the "LIMIT" button, programmed setpoints appear one after theother in the secondary display. L1, L2, L3 or L4 appear in the auxiliary displaydepending on the selected option. If it involves the 2 RELAYS option only thedisplay L1 and L2 appears.

The setpoints are displayed in sequence each time the "LIMIT" button ispressed, regardless of whether they are active or inactive. If you press thisbutton after the last setpoint is displayed, the secondary and auxilary displaysgo blank and the measured value appears in the display. While the setpointsare displayed, the other buttons remain operational.


Page 3-2

MAX/MIN The "MAX/MIN" button is used to display the max., min., and tare (or offset)values. When the button is initially pressed the MAX value saved after theRESET button was last pressed, is displayed in the secondary display. HIappears in the auxiliary display. When the button is pressed a second time,the smallest MIN value appears with LO displayed.

If tare has been saved or a temperature offset value for thermometers,pressing the "MAX/MIN" buttom third time brings about a correspondingly"tared off" value or offset and TA or OF appear in the auxiliary display.

If you press the button a fourth time, the secondary and auxilary displays goblank.

The "MAX" and "MIN" LEDs in the upper left part of the display light up eachtime the device reads a higher value that the one in the maximum valuememory or a smaller value than the one in the minimum value memory. Thenew value replaces the previous one in the memory.

To delete the maximum and minimum memories you call up "MAX or MIN" inthe secondary display. Then keep the "RESET" button pressed down and atthe same time press "MAX/MIN". Release the buttons in the reverse order.

During display of the maximum or minimum value the other keys remainactive.

The functions TARE, MAX/MIN and RESET can be activated in the same manner via the CN2connection when using the keyboard.

The devices are equipped with optocoupled functional inputs, which can be activated externallyvia contacts or logical operating states.

HOLD The HOLD function responds to the Low signal at PIN 2.Ground reference point is Pin 3.

If you activate HOLD the display value is frozen as long as Pin 2 is applied toground. The "HOLD" LED indicates that HOLD is active. This status influencesneither the internal functioning of the device nor the setpoint outputs, but theanalog and the BCD output (is frozen).

All of the named options are optocoupled with respect to the input signal. They can easily beconnected to the base plate using the connecters. They are recognised by the device as soonas they are installed. As a rule these options are factory-installed by the manufacturer. But aretrofitting is possible at any time. See above for the order code for optional printed circuit boards!


Page 4-2

In the figure below the individual slots for the output options are depicted.The options 2RE, 4RE and 4OP respectively can only be plugged into the M5 slot.The options RS2 and RS4 respectively can only be plugged into the M1 slot.Slot M4 is provided for ANA options.

The following 3 options can be installed at the same time:

Analog outputRS232C or RS485 (only one)2 relays, 4 relays or 4 optos (only one)

The BCD output can only be operated individually. This is connected directly to the main printedcircuit board using an 18 pin flatband cable.

The device equipped with RS232C or RS485 can be programmed with a PC using theRSKOSMOS software.

4.1 Analog output option (9180-V1XX)

4.1.1 Introduction

Using an additional card (option), which is installed into the base plate using a connector, theinstruments can be equipped with two output ranges (0 - 10 V or 4 - 20 mA). The outputs areisolated with respect to the input signal.

The option has an output connector [ANA (+) and ANA (-)], which supplies a signal of 0 to 10 Vor 4 mA to 20 mA proportional to the display value.

The two signal types cannot be used simultaneously. The selection is performed per menu sothat as soon as the card has been installed it is automatically released.

The most important values for the output signal range (OUT-HI and OUT-LO) are also enteredusing the keyboard. The analog output follows the changes in the display between maximum andminimum values programmed.

Display HOLD also stops the analog output.

The output signal can also be varied inversely proportional to the display if the lowest value ofthe display range is allocated to the maximum value of the analog (OUT-HI) and the maximumvalue of the display range to the lowest value of the output (OUT-LO).


Page 4-4

4.1.2 Installing the card

1. Take the electronics out of the housing and open the location on the housing marked in Fig.1 (arrow).

This opening is set up for the analog output. The option card is installed in slot M4.

2. Lightly press the tip of the card into the seat of the base plate until it latches in.If vibrations arise when using the device it might make sense to solder the card onto the baseplate at the corresponding lashes.

Before inserting the device back into its housing you should check to see if access to theprogramming level is not disabled (See page 2-5 concerning the DIP switch).

The figure shows the entire menu of module 40 for the configuration of the analog output. Thisappears only after the corresponding option has been installed. The module has at its disposal3 independent access menus, with which the following parameters can be determined:

Menu 41 -tYPE- : For selection of the analog type (0-10 V or 4-20 mA).Menu 42 -SCAL- : Allocates the display values for the range of the

output signal.Menu 43 -FILt- : For selection whether the change in output should be

a function of the display (filter ON) or the input signal(filter OFF).

4.1.6.2.1 Configuration of the unipolar analog outputfor bipolar sensor signals

In the display of type 9180 there is only a unipolar analog output available. To completelyreproduce the signal range of bipolar sensors on the analog output, its zero point must be shiftedaccordingly.

Example: The measurement range of a 8524-6001 force sensor (± 1000 N) should becompletely reproduced on the 4 - 20 mA analog output of the display.

The following linear classification should be achieved:

- 1000 N →→→→→ 4 mA0 N →→→→→ + 12 mA

+ 1000 N →→→→→ + 20 mA

Configuration steps:

1. In the configuration level 40 alternate between AinAout**(check German)**2. Scroll to menu 42 SCAL3. Scroll to out - HI4. Under item out - HI the display value is entered which should be allotted to the range end

of the analog output (+20 mA). In the example, +1000 is entered. Confirm by pressing"ENTER". out - Lo appears.

5. Under out - Lo the display value is now entered which should be allotted to the range startof the analog output (4 mA). In the example, -1000 is entered.

Here the zero point for the force automatically lies in the middle of the analog range (at 12mA in the example).

4.2 Options - limit value outputs - 2 relays (9180-VXXX1), 4 relays (9180-VXXX2) and 4 optocouplers ( 9180-VXXX3)

4.2.1 Introduction

The instrument can be extended with an option for 2 or 4 limit value outputs. This provides it withalarm and control functions.

All switching points have a time delay, which are programmed using a timer circuit (in seconds)or a symmetrical or asymmetrical hysteresis. Furthermore the limit value functions can also bedisabled. Additionally it is possible to configure the alarm so that it functions independently (eachalarm is activated by its switching point) or so that its activation depends on another alarm. Herethe latter function is designated TRAC.

The options are supplied in the form of plug-in cards. As a rule these cards are already pre-installed at the factory.

The following plug-in cards are available:

4.2.2 Function description

To guarantee adaptation to customer-specific requirements, the limit value alarm can beactivated individually or in various combinations.

1. Independent alarmsIndependent alarms are triggered if the display value reaches the switching point valueprogrammed by the user.

For the programming of this kind of alarm you also have to determine the followingparameters:

a. Activiating mode HI/LOIn "HI" mode the output is activated if the display value exceeds the value of the switchingpoint. In the "LO" mode the output is activated if the display value drops below the value ofthe switching point.

b. Time delay or hysteresisAll alarms can be provided with a switching delay or hysteresis. The switching delaycommences, when the display value exceeds or drops below a fixed value. There are twopossibilities when using time delay with hysteresis: the asymmetrical hysteresis delaysthe deactivation side of the output while the symmetrical hysteresis affects both sides of theswitching point.The switching delay can be programmed in seconds from 0 up to a maximum displayablevalue.The hysteresis can be programmed in points within the entire display range. The positionof the decimal point is determined by the previously set scaling parameter.

Figures 4.2.2a and 4.2.2b show the time delay realized by the timer circuit (dly) and by theasymmetrical hysteresis (hys-1) of two alarms (SET1 and SET2). They are programmed for theactivation in the respective modes HI (OUT1) and LO (OUT2).

Fig. 4.2.2c shows the time delay realized using symmetrical hysteresis. For the sake of simplicityonly one alarm is displayed in HI and LO mode.100 % of the selected hystereses (hys-2) are added to both sides of the switching point so thatone band arises within which the output is activated (HI mode) or deactivated (LO mode) ist. Theswitching delay with symmetrical hystersis is helpful for processes where the alarm should onlybe triggered between two specific points.

2. Logically combined alarmsThe switching points SET2 and SET4 can be combined by means of programming with thecorresponding switching points SET1 and SET3. This kind of alarm is not triggered bycomparison of the previously programmed display value, but by the comparison to the valueused to trigger the combined alarm.

When programming this alarm, the value of the first switching point is set (for exampleSET1 = 200) and the interval (Offset) determined between this and the second alarm (forexample TRACK2 = 50). Even if the value of SET1 changes, alarm 2 is always triggered50 points above SET1. If a negative value is programmed (-50), alarm 2 is activated 50points under SET1. Fig. 6.8.2d shows an example for a positive (TRACK2) and a negative(TRACK4) logic combination.

3. Correction of excess volumesDue to mechanical factors and assembly, for certain measurements, particularly forweighing and dosing, it is not possible to stop an operation precisely at a certain point(reaction time, "weight in fly"- effect).

The "weight in fly"- effect arises when filling vessels. In this process a flow inlet valve isclosed via an alarm upon reaching a programmed value. However, as there can still beresidual material in the pipe or in the air when the alarm is triggered, the desired filling levelis exceeded in the vessel.

The function AUTO TRAC is particularly designed to correct these excess volumes. Thisfunction is based on controlling the volume which exceeds the programmed amount ormeasure. To obtain the desired end value, the alarm is triggered with the excess amounttaken into account.

Only the SET2 alarm is equipped with an "AUTO TRAC" function. Here SET1 is the setalarm.To perform the "AUTO TRAC" function the desired switching point value is programmed inSET1. SET2 is automatically programmed as the logically combined alarm (initially it hadthe same value as SET1).

SET1 = desired switching point valueSET2 = AUTO TRAC

If the value of SET1 is reached, output 1 interrupts the process, but the filling volume risesto a value which is registered as the maximum value.

The measured maximum value is compared to the set value and the difference between thetwo is saved as the TRAC value and deducted from SET2. The value of SET2 is thussomewhat smaller than that of SET1. During the next measurement SET2 interrupts theprocess so that the effective end volume approximately corresponds to the programmedvalue in SET1.This process is updated in the following measurements.

4.2.6 Setting limit values

DefinitionThe flow chart on page 4-16 (programming instructions) corresponds to module 30 for programmingswitching points for equipment versions 9180-VXXX1, 9180-VXXX2 and 9180-VXXX3. If youonly have the option with 2 relays (9180-VXXX1) at your disposal, only menus 31 and 32 appearfor switching points SET1 and SET2.

Each switching point is programmed individually. If the programming of a switching point iscompleted, you can again access module 30 by pressing the "ENTER" key again (the message-Pro- appears in the secondary display) to configure the remaining switching points.

The flow chart shows that the switching points SET1 and SET3 are activated independently ofeach other, while switching points SET2 and SET4 can be activated in isolation as well as inmutual dependency. In this case SET2 is dependent on SET1 and SET4 is dependent on SET3.Switching point 2 is also equipped with an automatic track function.

Access to programming the switching pointsPress "ENTER" to go from the operating mode to the programming mode. Press the " " threetimes to reach level 30 Fig. 4.2.6a.

Fig. 4.2.6a

Information regarding the program flow chart (Page 4-16)As programming of the 4 switch points (page 4-18) as independent alarms is identical, thenumbers of the switch points in the figures were replaced by the symbol "#" so that these stepsapply for all switching points.When programming switching points 2 and 4 the options "ON" or "TRAC" (see Fig. 4.2.6c) leadto different subroutines. Each of these programs is dealt with individually on page 4-18.

Press "ENTER" again and the message "31-SET1" appears in the display for entry intothe programming menu switch point 1. Youare now on the switch point selection level.By pressing " " you can configure the nextswitching point.

4.3 RS232 (RS2) option

4.3.1 Introduction

The output option RS232C consists of an additional card (reference RS2), which is installed inthe M1 plug-in slot.The card has a 4-way telephone connection (Western socket).

The RS232 output can be used to establish a communications line with which a master canrequest from one or more display instruments data, for example, display value, switching point,maximum and minimum values, tare values (or offset in the case of a thermometer). Furthermore,various functions can be performed like tare, deletion of the memory for maximum, minimum andtare values and changes to the switching points.

Furthermore the instrument is provided with a command with which all the equipment settings canbe copied into a different device of the same type.The transmission speed can amount to 1200, 2400, 4800 or 9600 baud. The device adressingis programmable between 00 and 99.

Using the RS232C option you can connect the device to a master unit using the RS232Cinterface.The operating mode is semi-duplex. The series channel is only active, if the device, which isnormally in receiving mode until the message arrives, is in operating mode.

If the device receives a valid message, an action can immediately be performed (tare in display,deletion of the maximum/minimum value or tare memory, change of switching points) or aresponse of the polled device can be transmitted (display value, value of a switching point or themaximum/minimum value or tare memory). The transmission of the display value can berequested using an external switch(see page 4-28).

4.3.2 Protocol and commands

Two communication types are provided for: the DITEL mode operates with a simple protocol.Using the ISO mode corresponding to the ISO 1745 standard, communication can be performedmore effectively in an environment prone to distortion, as here the validity of a message is testedduring transmission as well as reception.As the depicted in the function table on page 4-24, the DITEL Protocol works with 1 or 2 bytesdepending on the type of command, while the ISO 1745 protocol always requires two bytes percommand.

A example in BASIC in SOURCE CODE you can findat the end of this manual.


Page 4-23

DITEL protocol

Format: 1 start bit, 8 data bits, 1 stop bit, no parity bit (none)

Receiving messagesA message transmitted to a device must consist of a sequence of ASCII codes:

D d C C X ........................................X CR

Symbol "" [ASCII 42] signifies the start of the message. Two address bytes between 00 and 99 ( D = tens digit, d = ones digit ). One or two ASCII codes (CC) for the desired command according to the function table on

page 4-24.If it involves a command to change parameters, the new value is transmitted in the form of asymbol byte "" [ASCII 43] or -[ASCII 45], followed by a block of n-ASCII codes including decimalpoint.Symbol "CR" [ASCII 13] signifies end of message.

Transmitting messagesThe format of messages transmitted from a device as a response to a data requestcommand is transmitted as follows:

SP X ........................................X CR

One byte for a space [ASCII 32]. A text (desired value) consisting of a symbol byte [ASCII 43] or - ]ASCII 45] followed by a block

of n-ASCII codes including decimal point. Symbol "CR" [ASCII 13] signifies end of message.

If it involves instructions or commands for change of parameters the device does not respond.

Transmitting a message to the deviceA message from the master unit must consist of the following code sequence:

SOH D d STX C C X ............... X ETX BCC

One SOH byte for the beginning of the message [ASCII 01]. One byte for the significance 10 and one byte for the significance 1 of the addresses of the device

being transmitted to. One STX byte for text beginning [ASCII 02]. Two command bytes according to the function table. For commands regarding parameter changes, a block of n-bytes for the numerical value

including the decimal point.

One ETX byte for end of text [ASCII 03]. One BCC control byte is computed as follows:

When executing an Exclusive-OR operation for all bytes between STX (not included) and ETX(included)

- If the byte in ASCII code lies at ≥ 32 it can be used as a BCC control byte.- If the byte in ASCII code lies at < 32 you obtain the BCC control byte by adding 32.

Receiving messages from the deviceThe typical message format, which the device supplies as a response to a command,appears as follows:

[1st level -Pro-, 2nd button "TARE", 3rd key "ENTER"].

4.4 RS485 (RS4) option

4.4.1 Introduction

The output option RS485 consists of an additional card (reference RS4), which is installed in theM1 connection slot of the device's base plate.The card has a Western-type telephone connection terminal with an output at the rear side of thedevice.

Using the RS485 you can set up a communications line by means of which a master unit canrequest data from one or more display instruments, like e.g. the display value, switching points,min. and max. values, tare values (or offset in the case of a thermometer). Furthermore externalfunctions can be performed like the deletion of the memory for min., max. and tare values andchanges to the switching points.

The model 9180 is also provided with a command you can use to copy the programming intoanother device of the same type.The option can be configured completely via software, i.e. baudrate (1200, 2400, 4800 or 9600),device addressing (programmable between 00 and 99), type of protocol (DITEL or Standard ISO1745) and time delay.

Using the RS485 option up to 31 devices can be connected to the main device with output RS485.The function mode is half-duplex. The channel is only active if the device, which is normally inreceiving mode until a message is obtained, is in operating mode.


Page 4-34

If the device receives a valid message an action can be performed immediately

4.4.2 Protocol and commands

Two modes of communication have been provided for:The DITEL mode operates with a simple protocol. Using the ISO mode, corresponding to the ISO1745 standard, the communication can be performed effectively in a distorted or disturbedenvironment, as here the validity of a message has to be checked both during transmission aswell as reception.As in the function table shown on page 4-35, the DITEL protocol operates with 1 or 2 bytesdepending on the type of command, while the ISO 1745 protocol needs two bytes per command.

A example in BASIC in SOURCE CODE you can findat the end of this manual.

DITEL protocol

The word format 1START bit, 8 data bits and one StOP bit.

Sending messages to the deviceA message sent to the device must consist of a sequence of ASCII codes:

D d C C X ........................................X CR

Symbol "" [ASCII 42] signifies the beginning of the message. Two address digits (between 00 and 99). One or two ASCII codes for the desired command in accordance with the function table on page

4-35.If it involves a command for changing parameters, the new value is transmitted in the form of asymbol byte [ASCII 43] or -[ASCII 45], followed by a block made up of n-ASCII codes includingdecimal point.

Symbol "CR" [ASCII 13] signifies end of message.


Page 4-35

Receiving messages from the deviceThe format of messages sent by the device as a response to a command for data requestis as follows:

SP X ........................................X CR

One byte for space [ASCII 32]. One text (desired value) consisting of a symbol byte [ASCII 43] or - ] ASCII 45]

followed by a block made up of n-ASCII codes including decimal point. Symbol "CR" [ASCII 13] signifying end of message.

Example:

If it involves instructions or commands for changing parameters the device does not respond.

Protocol ISO 1745

For the word format, 1 start bit, 7 data bits, 1 parity bit and 1 stop bit are needed.

Sending messages to the device

SOH D d STX C C X ............... X ETX BCC

One SOH byte for the beginning of the message [ASCII 01]. One byte for the tens digit and one byte for the ones digit of the device address to be targeted. One STX byte signifying text beginning [ASCII 02]. Two command bytes in accordance with the function table. For commands to change parameters one block of n-bytes for the numerical value including

decimal point. One ETX byte for end of text [ASCII 03]. One BCC control byte is computed as follows:

Performance of an Exclusive-OR for all bytes between STX (not included) and ETX(included)

- If the byte lies in ASCII code at ≥ 32 it can be used as BCC control byte.- If the byte lies in ASCII code at < 32 you obtain the BCC control byte by adding 32.

Example:

Protocol ISO 1745

Messages received by the deviceThe typical message format which a device supplies as a response to a command from amaster unit, appears as follows:

1. For commands requesting a value:

SOH D d STX X ............... X ETX BCC

One SOH byte for the beginning of a message [ASCII 01]. 2 address bytes ( D = tens digit, d = ones digit ). One STX byte for beginning the text [ASCII 02]. n-bytes corresponding to the desired value (including symbols and decimal point). One ETX byte signifying end of text [ASCII 03]. One control byte computed as above.

If the master unit transmits a message with the address 00, the command is interpreted by all thedevices in the network and you obtain a response.


Page 4-37

2. Commands not requesting a value:

D d ACK or D d NAK

The device sends acknowledgement that the message has been received.

If the message was received and interpreted correctly, the response consists of two addressbytes and one "ACK" byte [ASCII 06].

If the received message was not recognized and errors have arisen, the response consists ofaddress bytes and one "NAK" byte [ASCII 21].

If the master unit transmits a message with the address 00, the command is interpreted by all deviceson the network and you obtain a response.


Remove the electronics system from the housing and open the housing's rear wall at the locationsmarked in Fig. 4.4.3. This opening is designed for the RS485. The option card is installed into theM1 slot.Carefully press the nose of the card into the slot on the base plate until it latches in. If vibrationsoccur when the device is in operation it makes sense to permanently solder the card to the baseplate at the corresponding lashes.

With D.T.E., up to 31 display instruments can be connected to the same bus. Here each devicereceives its own address between 00 and 99.The address 00 applies for every connected device and can be used for commands by the masterunit to which the devices need not respond.A command which is sent to the address 00 is simultaneously executed by all devices(broadcast).

Jumper J1

Optionsplatine RS4

To connect different devices via the RS485 interface, a terminating resistor (Rt) with 120 Ω mustbe attached to both ends of the data line.The display instruments already contain this resistor Rt, which is connected internally to theoutputs 3 and 4 of the CN5 connection by means of the jumper J1 on the RS4 card. If severaldevices exist on the bus, J1 only remains connected to the last subscriber. The jumpers of all theother devices are to be removed.

4.5 BCD output option

4.5.1 Introduction

The BCD output option supplies 5 1/2 digits in BCD code.Using the TRISTATE, the output remains highly resistive so that various display instruments canuse the same communications bus.

All of the outputs are compatible with TTL or 24 V logic and are optically isolated with respect tothe input signal to the extent that the card is supplied to an external voltage between 5 V and24 V.

As long as the TRISTATE input is set to "low", the data output is updated in the same cycle asthe data appears in the display. If the TRISTATE input is set to "high", the impedance of all theoutputs including DATA VALID is increased so that the same bus can also be used for otherapplications.The DATA VALID signal is updated when the data are available in the communication bus.

When the display is on HOLD the data output is also stopped.

The output signals can operate with positive or negative logic. The selection of the logic type isperformed by interchanging the ICs of the option card as well as resetting two connectablejumpers. Programming using the keyboard is not necessary.


Page 4-47


Remove the electronics from the housing and open the location marked in Fig. 4.5.2. This openingis designed for the BCD output option.

The BCD card is connected to the J6 socket on the base plate of the device via a flatband cable(see Figure 2).

This is easier when you take out the card.

If the card is connected to the device, it is inserted horizontally into the base plate. It is designedso that it slides and latches into the base plate.Guiderails which hold the card are located in the housing.

Fig. 4.5.2

Fig. 4.5.2a


Page 4-48

The card is inserted into the slot in the front panel (Fig. 4.5.2b) and lies in the opening of the inputcard.

The flat cable is bent and lies on the transformer (Fig. 4.5.2b).

Then the electronic unit with the BCD card (Fig. 4.5.2b) is inserted back into the housing. Sincethis option must not be configured by the software, the device is now ready for operation.

4.5.4 Changing the logic

The BCD output card can be configured for data output in positive logic (the bit is enabled, if ithas a higher level with respect to GND) or in negative logic (the bit is enabled, if it has a lowerlevel in relation to GND).If the device is connected to an SPS (PLC), the card must be configured accordingly.

To change the logic, the ICs: IC6, IC7 and IC8 supplied with the card, must be interchanged andthe jumpers J1 and J2 adjusted as follows:

Positive logic: Jumper J1 and J2 to position 2-3IC6, IC7, IC8: UDN2981

Negative logic: Jumper J1 and J2 to position 1-2IC6, IC7, IC8: UDN2803

The changes specified affect the logic of all the signals:data bits, polarity, measurement value overshoot and data valid.

Connection diagram of the BCD option:


Page 4-52

The following schemes depict one of the BCD outputs in positive and negative logic respectively.

Positive logic

Negative logic

The TRISTATE input is triggered externally and is always active at level "1".

In positive logic the signals are active atlevel "1" and negative at level "0".The POLARITY is positive (+), if the bit is ona high level and negative (-), if it is on a lowlevel with respect to GND.The MEASUREMENT VALUE OVER-SHOOT is positive, if the bit is on a high leveland negative, if it is on a low level. Whenthere is measurement value overshoot, thefour lowest digits (D0, D1, D2 und D3) areFFFF.

Parameters of the output transistors: Vmax = 40 V Imax = 100 mA

Pin assignment corresponds to pages 4-49/50
