Appendix E: Optional interface: Profibus

This appendix describes the Profibus DP interface of the active contact flange. Delivery status of the node number of the active contact flange is set to 4. Byte order: big endian (most significant byte stored at the lowest address). The active contact flange control is always Profibus slave.

ATTENTION

Be aware of the tenth-units for the signals These units are in use to avoid decimal numbers in this interface.

DIP-switch for PROFIBUS-address

The PROFIBUS-station address is set via the DIP-switch on the front of the module. PROFIBUS supports the address range 3 … 125. A change of the PROFIBUS -station address via the DIP-switch cannot occur during running operation. Only after the CPU has been restarted will the changed station address become effective.

Figure 14: Setting of the PROFIBUS-station address

In the delivery status of the active contact flange the station address is configured to 4. Error codes

The error codes are transmitted in the same way as in the Ethernet TCP/IP interface. The same error codes are in use.

Bus termination

To ensure smooth operations, the Profibus bus line must be terminated on either end. When using a plug designed for PROFIBUS the termination can be switched on/off via a switch at the connector shell.

Plug specification

To establish connection with the plug, the following shielded plug is recommended:

Phoenix plug SUBCON-PLUS-PROFIB/AX/SC

Material number: 2744380
