Profibus-DP Protocol

1 Safety

Note:

The operating instructions must be kept near the control unit.

1.1 Intended use

Profibus DP is part of the basic print for MEAG and MDDR/T electronics. It is not intended for any other use.

1.2 Duty of instruction

The operator is responsible for the training and safety of the operating personnel. For this reason, it is very important that these operating instructions are distributed to these persons.

Operating personnel responsible for the installation, operation or maintenance of the control unit must have read and understood these operating instructions.

1.3 Accident prevention

The control unit complies with the international safety standard.

For your own safety, please observe all accident prevention and safety regulations that are contained in these operating instructions and that apply locally.

Note:

Warning and instruction plates must be kept clean and must not be removed or covered.

Immediately replace any illegible warning and instruction plates.

1.4 Operation

The control unit may only be operated by instructed and trained personnel. Personnel must be familiar with all display and control elements.

1.5 Electrical installation

Have authorised personnel perform the installation procedures. • Observe regulations issued by local safety authorities. • Secure the supply lines according to local regulations.

• Check the operating voltage and frequency with respect to the information provided on the identification plate and in the control cabinet.

• Connect the control unit power supply according to the connection diagram. • When connecting up or repairing the control unit, make sure that the power

supply is interrupted by disconnecting all poles and that it cannot be restarted.

• Check the electrical installation on a regular basis.

2BDescription

2 Description

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

The SIEMENS SPC3 Profibus controller is used as the communication module according to standard EN 50170.

In the event of a failure of the device (deadlock), the corresponding diagnostic flags are set in the protocol. These are evaluated by a master unit, which responds accordingly. 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

Profibus controller

SIEMENS SPC3

Protocol Profibus DP built to EN 50170

The protocol consists of 24 bytes of transmitted and received data respectively. (Standard protocol)

The DMS transmitter also includes a compact protocol.

Baud rate A baud rate of max. 12 Mbaud is possible. The device automatically adapts to the configured baud rate, so that no settings 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 the

integrated terminal resistor. Using the wrong bus termination can render communication impossible on the entire Profibus.

Cable lengths The maximum cable lengths per bus segment are limited by the baud rate:

1.5 Mbaud: 200 m per segment 12 Mbaud: 100 m per segment Repeaters must be used for longer cables.

Deadlock If the device switches to an invalid state / deadlock, the SPC3 Profibus module detects this by means of a watchdog and stops the data transfer. The relevant diagnostic data are set in the Profibus protocol and can be evaluated, e.g. by the master.

Identification AEE0 (registered by Profibus user organisation) Configuration Configuration is undertaken using the GSD file

BDC_AEE0.GSD, the file BDC_AEE0.DIB is used for the

device symbol. Since the data format of the STANDARD protocol is identical to the MEAF electronics, the GSD file BUZ_AEE0.GSD can also be used.

When replacing an MEAF with an MEAG, the device can therefore be swapped without the need for configuration.

Connection check (timeout)

The connection check is only active if the parameter SYS.REM = REMP is set. The monitoring time is set at parameter

PBDP.TOUT. In the event of a timeout, an alarm is displayed on the device. Certain devices stop in the event of a timeout for safety reasons.

(9)

2.2 Device parameters

The following parameters are directly connected to the Profibus interface. Also see operating instructions for device.

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

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

3BProtocol structure

3 Protocol structure

The STANDARD protocol comprises 12 words of consistent transmitted and received data. These have a symmetrical structure. These include 4 bytes each of control or status bits which are transmitted in all cases. 16 bytes contain variable data (data records) which are defined by a number and an index (number/index of transmitted 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 byte is transmitted to the lowest address.

Transmitted data labelled as n.u. = not used are ignored by the device. Received data labelled as n.u. are set to 0 by the device.

The consistent data can only be read / written in the connected control units via special functions

(e.g.: SIMATIC S5 = FB192, SIMATIC S7 = SFC14/SFC15).

1) Only the control or status bit values are transmitted.

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

(11)

3.2 Data records

The data records are defined by numbers and indices.

In the case of a master device, a transmitted and a received data record can be selected simultaneously. The transmitted data record numbers and indices are then returned by way of acknowledgement.

3.3 Index of transmitted / received data record

The 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 actually used.

7 Modification to 2) received data record

1 = New received data record or modified contents

1. "Handshake bits" when modifying the transmitted data. These can be used 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 device sets the status bit "Acknowledge modification to transmitted data record". This enables the control system to detect that the device has read the data and to delete the control bit "Modification to transmitted data record". The device then also deletes the status bit "Acknowledge modification to transmitted data record".

2. "Handshake bits" when modifying the received data. These can be used where necessary. If the received data are modified, the device sets the status bit "Modification to received data record". After reading, the plant control system sets the control bit "Acknowledge modification to received data record". This enables the device to detect that the control system has read the data and to delete the status bit "Modification to received data record". The control system then also deletes the control bit "Acknowledge modification to received data record".
