How to configure an Anybus PROFIBUS Slave module with a Siemens Step7 PLC

SCM-7032-026

Rev 2.1

4 Hardware Configuration

1.1. Anybus module settings

Anybus Communicator and the X-gateway:

For the Anybus Communicator and the Anybus X-gateway the address is set by switches. See the description

of the Anybus Slave below. In the case with the Communicator the configuration can also be done by

mailbox commands.

Anybus-PCI, Anybus-IC and the Anybus-CompactCom:

For the Anybus-PCI, IC and CompactCom the address is set by the application. See the respective manual or

addendum for more details.

Anybus-S Slave:

The address setting is done with the two rotary switches on the Anybus Slave module. However in some

applications the application interface is used to set the addresses with software. The address is set to 1 in

this example.

The Anybus-S Slave Interface also has a terminating switch.

• The terminating switch should be set to “ON” if:

o The module is the last node on the network => physical end of the bus.

o No other termination is used at this end of the network.

• The terminating switch should be set to “OFF” if:

o There are other nodes on both sides of the module in the network.

o The module is the last node on the network and a PROFIBUS D-SUB connector is used

which is equipped with a built in and activated termination.

Figure 2 Anybus-S PROFIBUS hardware settings.

Note: The PROFIBUS network must always be terminated at both ends.
