2BDescription


2 DescriptionThese operating instructions apply for electronics for MEAG and MDDR/T (referredto in these operating instructions as "device") . In these devices, Profibus DP isintegrated on the basic print and is therefore available at all times.

The SIEMENS SPC3 Profibus controller is used as the communication moduleaccording to standard EN 50170.In the event of a failure of the device (deadlock) , the corresponding diagnostic flagsare set in the protocol. These are evaluated by a master unit, which respondsaccordingly. Conversely, in the event of a master failure or connection problems,the device can effect a control stop. This restores the plant to a safe condition.

2.1 Technical data

Profibuscontroller

SIEMENS SPC3

Protocol Profibus DP built to EN 50170The protocol consists of 24 bytes of transmitted and receiveddata respectively. (Standard protocol) The DMS transmitter also includes a compact protocol.

Baud rate A baud rate of max. 12 Mbaud is possible. The deviceautomatically adapts to the configured baud rate, so that nosettings need to be made.

Connection See operating instructions for device

Bus termination If the device is at the end of the Profibus, use the plug with theintegrated terminal resistor. Using the wrong bus terminationcan render communication impossible on the entire Profibus.

Cable lengths The maximum cable lengths per bus segment are limited bythe baud rate:1.5 Mbaud: 200 m per segment12 Mbaud: 100 m per segment

Repeaters must be used for longer cables.

Deadlock If the device switches to an invalid state / deadlock, the SPC3Profibus module detects this by means of a watchdog andstops the data transfer. The relevant diagnostic data are set inthe Profibus protocol and can be evaluated, e.g. by themaster.

Identification AEE0 (registered by Profibus user organisation)

Configuration Configuration is undertaken using the GSD fileBDC_AEE0.GSD, the file BDC_AEE0.DIB is used for thedevice symbol. Since the data format of the STANDARDprotocol is identical to the MEAF electronics, the GSD fileBUZ_AEE0.GSD can also be used.When replacing an MEAF with an MEAG, the device cantherefore be swapped without the need for configuration.

Connectioncheck (timeout)

The connection check is only active if the parameter SYS.REM= REMP is set. The monitoring time is set at parameterPBDP.TOUT. In the event of a timeout, an alarm is displayedon the device. Certain devices stop in the event of a timeoutfor safety reasons.

2.2 Device parametersThe following parameters are directly connected to the Profibus interface. Also seeoperating instructions for device.

SYS.TYP The structure of the transmitted and received data variesaccording to the selected type of scales.

SYS.REM The transmitted data are only accepted by the device if theparameter is set to REMP. The received data can be readwith any setting.

3BProtocol structure


3 Protocol structure

The STANDARD protocol comprises 12 words of consistent transmitted andreceived data. These have a symmetrical structure. These include 4 bytes each ofcontrol or status bits which are transmitted in all cases. 16 bytes contain variabledata (data records) which are defined by a number and an index (number/index oftransmitted and received data record; one byte each) . In these 16 bytes, 16 bit(WORD) or 32 bit (DWORD) data can also be transmitted. The highest-order byteis transmitted to the lowest address.Transmitted data labelled as n.u. = not used are ignored by the device. Receiveddata labelled as n.u. are set to 0 by the device.The consistent data can only be read / written in the connected control units viaspecial functions(e.g.: SIMATIC S5 = FB192, SIMATIC S7 = SFC14/SFC15) .

2) The control bits and data in the transmitted data record are only accepted ifparameter SYS.REM = REMP.


11/116



3.2 Data recordsThe data records are defined by numbers and indices.In the case of a master device, a transmitted and a received data record can beselected simultaneously. The transmitted data record numbers and indices arethen returned by way of acknowledgement.

3.3 Index of transmitted / received data recordThe index allows several variants to be managed under the same data record (e.g.different recipes) .Most data records do not have an index. In this case, the value should be set to 0.In the description of the data records, the index is only indicated where it is actuallyused.

1. "Handshake bits" when modifying the transmitted data. These can beused where necessary.If the plant control system modifies the transmitted data, it sets the control bit"Modification to transmitted data record" at the end. After reading, the devicesets the status bit "Acknowledge modification to transmitted data record". Thisenables the control system to detect that the device has read the data and todelete the control bit "Modification to transmitted data record". The device thenalso deletes the status bit "Acknowledge modification to transmitted datarecord".

2. "Handshake bits" when modify ing the received data. These can be usedwhere necessary. If the received data are modified, the device sets the statusbit "Modification to received data record". After reading, the plant controlsystem sets the control bit "Acknowledge modification to received data record".This enables the device to detect that the control system has read the data andto delete the status bit "Modification to received data record". The controlsystem then also deletes the control bit "Acknowledge modification to receiveddata record".
