Setting the PROFIBUS address

Once the PROFIBUS slave has been successfully added to TwinCAT, the PROFIBUS address of the slave can be set. In this step the address is set in TwinCAT, so that the PROFIBUS slave can be reached by the PROFIBUS master via this address.

Possible addresses are 1 to 125, whereby the lower addresses are intended for the master. Addresses 0 to 127 are reserved.

2. Enter a value for the PROFIBUS address in the field Station No, e.g. "30".
