2.4 INTRODUCTION TOMFW-01

MFW-01, WEG Fieldbus Module, is an intelligenttranslator of communication protocols, a gateway

between WEG equipment and a Fieldbus communicationnetwork (Profibus DP, DeviceNet and Modbus-RTU).MFW-01 can translate part of the data between the twodifferent protocols and program the data that should beexchanged.

The programming of the data, parameters or basicvariables of WEG equipment that should be available athigh level, is realized by a Software, MFW.exe forWindows, which has the capacity to configure whichparameter or basic variable of WEG equipment shouldcorrespond to which address at the high Fieldbuscommunication network.

MFW-01 is fitted with a module called as Anybus that issupplied by HMS Fieldbus Systems AB. This company isassociated with the certifying entities of the respectiveFieldbuses that are being used.

Anybus module implements all Fieldbus, hardware andsoftware communication protocols.

Besides the Anybus module, MFW-01 has: switchedpower supply, microcontroller, connection for RS-232and RS-485 interfaces and six 24Vdc digital inputs andfour digital relay outputs.

The microcontroller is responsible for the serialacquisition and changing of the parameter content ofWEG equipment according to WEG protocol and for theupdating of the variables at the Dual Port RAM.


12/71

2 INTRODUCTION

The microcontroller also identifies which Fieldbus deviceis connected to realize the configuration of the addressing

in the DPRAM variables.

The variables are allocated on the DPRAM by means of aaddressing table resident on EEPROM, that must beconfigured previously by the PC configuration Software,MFW.exe, and transferred to MFW-01 serially.

By means of this Software the user can configure,according to his needs, which parameters shall be read orcontrolled.

Once the required configuration parameters are defined,they will be updated cyclically at their respectiveaddresses. If a change of that configuration is required,the user can perform it through the new configuration.

Simplified block diagram of the MFW-01:

As shown in the sample above, the Master can read thecontent of the Parameter P121 of a CFW-07 that isconnected to the address No. 4 of WEG network and controlthis parameter by changing its logical control variable V00,

by reading and writing only the I/O of the correspondingFieldbus network address.

5 DEFINITIONS

MFW-01 has the advantage to be connected through RS-485 WEG network to several equipment.

The max. number of available stations on this WEGnetwork will depend on the number of the requiredvariables and on the time required for their updating.

The max. allowed number of variables is of 24 inputs and24 outputs. Each variable is a word with 16bits.

The stations connected to this mini-network can bedifferent WEG equipment: SSW-03, 04, CFW-05, 06, 07,08, 09, MDW-01, SCA-04, CTW-(A)03 and all new

equipment that are fitted with WEG serial communicationprotocol.

Through the equipment response to each answeringFrame or to the variable change, MFW-01 will checkwhich equipment are operating correctly. This informationwill be available at the specific addresses of the DPRAMinput that will be made available at the higher network.

The available DPRAM variables for the communicationbetween the Master and the MFW-01 are so disposed toservice several Fieldbus protocols, make easy and viablethe implementation of the software on the PLC or on PCand to establish the communication with all WEGequipment that have WEG serial communication protocol.

O MFW-01 controls the variables of all equipmentindependent of the type or their number. The variablecommunication will be realized only through theirrespective addresses:

5.1.9 Errors Related tothe Serial

Communication

They do not disable WEG equipment;

They do not deactivate the fault relay;

They inform only through display and in logical statusword.

Type of Errors:

E22: longitudinal parity error (BCC); E24: when changing of parameters is attempted that can not be changed with running motor; E25: not existing variable; E26: set value out of permitted range; E27: write attempt on read-only variable, or logical control

disabled;

E29: serial interface error (available only in some WEGequipment).

Note.:These errors can be observed through reading of the statusvariable of WEG equipment.

NOTE!Take care with the parameter incompatibility. Functionincompatibilities are indicated in the respective Manuals ofWEG equipment that are being applied.

5.1.10 Times at WEGNetwork

Variable Updating Times at dual port RAM:

As the communication between WEG equipment and theMFW-01 is serial, the variable updating rate at DPRAM

depends of the serial baud rate of WEG equipment.

The standard baud rate of WEG equipment is 9600bps.This baud rate reduces the time of the DPRAM variableupdating, but does not reduce the communication time ofthe Fieldbus network, since the variables are alwaysavailable at the Fieldbus network, updated or not.


24/71

5 DEFINITIONS

Times of WEG protocol:

Data receiving/transmission rate: 9600bps 1bit / 104,2usEach data word has 10bits 1,04ms

A inquiry frame has 8 word 8,33ms

A answering frame to a inquiry has 14 word 14,58ms

A changing frame has 15 word 15,63ms

A answering frame to a change has 2 words 2,08ms

An updating of a requested variable (with immediate answer) 22,91ms

A changing of a write variable (with immediate answer) 17,71ms

Note.: For each frame without answer will occurs a delay of

50ms.

The same frame will be sent up to three timesconsecutively, 150ms, after that an error will be indicatedon the respective status word, (set bit).

As the variables are processed cyclically, a newprocessing is realized.

When at the next processing the answer is correct, therespective status word is reset (reset bit).

NOTE! In order to avoid communication delay, maintain all WEG

equipment ON and disconnect defective equipmentimmediately from WEG network.

All drivers and their connections with WEGcommunication network must be in excellent operationcondition and submitted to preventive maintenance indetermined intervals.

The total updating time of the DPRAM variables dependson the number of variables that should be processed.

It reads the description of the n output variable at the EEPROM

It reads the content of the n output variable at the DPRAM

It reads the value of the digital outputs at DPRAM and updates the digitaloutputs

It generates an inquiry frame of the n output variable

It sends an inquiry frame of the n output variable

I receives the answer of the concluded change

It updates at DPRAM the status word and the digital inputs

It increments n + 1

The outputs are processed up to the last variable

Since the initialization, the MFW-01 working cycle followsalways this flowchart, processing firstly all read variablesand then all write variables, returning cyclically to the firstread variable.

Note:n shown above is used only to exemplify the sequentialaddress of the variable processing: first variable, secondvariable...


26/71

5 DEFINITIONS

The total updating time can be obtained by the followingequation:

Time = ( number of input variables x ( 22,91ms + 1,2ms ))+ ( number of output variables x ( 17,71ms + 1,2ms ))

Note:Do not consider the status variables in the number of inputvariables, that they will be used according to the number ofused blocks. See DPRAM Definition Table.

Please consider only the output times in the total sumwhen they have been changed.

NOTE!This time will be maintained, when no communication erroroccurred with WEG equipment that are part of WEGcommunication network.

The digital inputs are updated at every DPRAM access.Thus the max. updating time of the digital inputs is22,91ms, but when communication error has occurred,this time will be extended in 50ms.

The digital outputs are only updated when a data changeis made. Thus the maximum updating time of the digitaloutputs after a data change may be 22,91ms, but whencommunication error has occurred, this time will be of50ms.

COMMUNICATION INTERFACES 6

27

The physical connection between WEG equipment and theMFW-01 of WEG network is realized in two standard ways:

RS-232 point to point up to 10m;

RS-485 multi-point, with galvanic insulation, up to 1000m;

6.1 RS-485 WEGINTERFACE

For serial communication of WEG network equipment

The RS-485 Interface permits the interconnection up to30 WEG equipment to one MFW-01 (master), allocatingan address (1 to 30) to each WEG equipment set to thisaddress.

The connection of the participants is realized by means ofa twisted pair cable.

The signal levels are according to EIA STANDARD RS-485 with differential receiver and transmitter.

NOTE!If WEG equipment is fitted only with the standard RS-232interface, you must couple an level conversion module toconvert the level from RS-232 to RS-485, designated asMIW-02 interface module for RS-232/RS-485communication and a communication cable for RS-232.

6.1.2 RS-485 WEGConnection It must be connected directly point to point or in network

with each parallel branch.

6.1.3 RS-485 WEGCares

Factors such as unbalance and mutual cable capacitancetend to reduce the network noise immunity.

In the practice, the cable cross section must be larger orto 26AWG (0,14mm), shielded twisted pair cable.

The cable shield must be grounded at all connections ofthe network through the RS-485 connectors.


35/71


29

All network equipment must be grounded.

For the serial interface cables use separate conduits .

Dont forget to install terminating resistors at the ends ofthe network at disconnect the resistor from the internalnetwork equipment.

Relays, contactors, solenoid valves, coils ofelectromechanical brakes installed near the MFW-01may generate interferences in the control circuit. Toeliminate this interference, connect RC suppressor filterin parallel with the coils of these devices, when ACsupply is used and free-wheel diode, when DC supply isused.

6.1.4 RS-485 WEGCable Definition

The EIA Standard does not specify a standard cable forRS-485, but it recommends some cares to be take duringit selection.

To reduce the cable reflection at maximum, connect aresistor (Rt) at each cable end. This resistor must havethe same impedance as the characteristic cableimpedance.

These resistors are already available on MIW-02 bysetting the S1 switch to ON.

The max. ohmic resistance of the cable is determined bythe following equation:

RLOOP= Rt (1,5 Vo)Vo

where:Vo = voltage at the cable end (V); max. 1,5V;Rt = terminating resistor (ohms);RLOOP = cable resistance (ohms)

The noise level variation ( VR ) is defined by:

VR = VO - 0,2

Thus, the larger the cable cross-section, the lower will bethe resistance and the larger will be the noise levelvariation.

11.10 TERMINATION The end nodes in a Profibus-DP network has to beterminated to avoid reflections on the bus line. The AnyBus-SProfibus-DP module is equipped with a termination switch toaccomplish this in an easy way. If the module is used as thefirst or last module in a network the termination switch has tobe in ON position. Otherwise the switch has to be in OFFposition.

NOTE!If an external termination connector is used the switch mustbe in OFF position. Always use an external terminationconnector.

Termination switch ON Bus termination enabledIf the module is the last or firstmodule, the bus termination has tobe set on, or an externaltermination connector has to be

used.Termination switch OFF Bus termination disabled.

11.11 NODE ADDRESS Before configuring the AnyBus-S Profibus-DP module thenode address has to be set. This is done with two rotaryswitches on the module, this enables address settings from1-99 in decimal format. Looking at the front of the module,the leftmost switch is used for the ten setting and therightmost switch is used for the setting of the integers.

Example:Address = (Left Switch Setting x 10) + (Right Switch Setting x1).

PLEASE NOTE: Another way of setting the node address isvia the mailbox frame.

FB_SET_NODE_ADDRESS. The node address range isthen extended to 1-125.

PLEASE NOTE: The node address can not be changedduring operation.

11.12 GSD FILE Each device on a Profibus-DP network is associated with aGSD file, containing all necessary information about thedevice. The network configuration program during

configuration of the network uses this file.

The latest version of GSD file can either be downloaded fromthe webpage http://www.hms.se/fbfiles.htm or received bycontacting HMS.

11.13 INDICATIONS The module is equipped with four LEDs mounted at the frontand one LED on the board, used for debugging purposes.The front LEDs can be mounted in two ways, either topmounted or angle mounted. The function of the LEDs are

described in the table and figure below.

11.14 ADDITIONALINFORMATION

ABOUTPROFIBUS DP

The connector of the MFW-01 to Profibus DP is a DB-9that must be special for the connection of two cables.

Connections supported by the board AnyBus-S ProfibusDP

1 Polled I/O

NOTA!

MFW-01 has been developed to operate in Exchange PolledI/O operation mode with optimized number of I/O.

Please find below an example using a Profibus DP networkwith a ZE-200 DP CPU (CL-200) from Bosch:


64/71

11 PROFIBUS DP

The module must be configured in file MFW.GSD inC:\Bosch\WinSPS\GSD\Profibus\Dp\Gsd\MFW.gsd with anASCI editor for:

Input _xxx Words .......... equal to the number of inputs.

Output _xxx Words..........equal to the number of outputs.

This means that you must configure exactly the samenumber of inputs in word that will be used as reading by themaster and exactly the same number of outputs in word thatwill be used as changes by the master. See Item 5.2

Please consider all bytes up to the address of the lastdesired variable, the same that has been configured inMFW.exe.

To optimize the system relating to the number of variablesthat are available in the network, thus requiring the updatingtime, MFW-01 has been developed to program itself to thesame number of I/O-variables that have been programmedin MFW.exe in addition to the status and control words.

NOTE!If the number of I/O is not compatible, there will be no dataexchange nor acknowledgment of MFW-01 in the Profibus

DP network.

12.1 INTRODUCTIONTO MODBUS RTU

Modbus RTU is a Fieldbus system from the companyModicon, that is a company of Schneider Automation group.

12.2 SPECIFICATIONS The media for the Fieldbus is a copper cable composed ofone twisted pair. The baud rate is as standard 19200 Bit/sbut can be modified on the card between 1200 Bit/s to50 000 Bit/s. The Modbus RTU network can consist of 247slaves but only one Master. The master always initiates thecommunication with a question ( called a query ) and theslave with the right slave address answers the question witha response. The maximum amount of data for the ModbusRTU DT module are 480 Byte out/module and 480 Bytein/module.

12.3 SYSTEM SETUP The Modbus RTU system is often used in a combinednetwork with Modbus PLUS. However the Modbus RTU

module can be combined with a master and can be operatedwithout any Modbus PLUS system. Below you can see atypical Modbus RTU network.
