Setting the PROFIBUS Address
There are two ways to set the PROFIBUS address:
1. Via p0918
– To set the bus address for a PROFIBUS node using STARTER, first set the rotary
– Then use parameter p0918 to set the address to a value between 1 and 126.
2. Via the PROFIBUS address switches on the Control Unit
– The address is set manually to values between 1 and 126 using the rotary coding
Note
The rotary coding switches used to set the PROFIBUS address are located beneath the
cover.

Cyclic communication is not (yet) running.
Note:
The PROFIdrive is ready for communication when the Control Unit is ready for
operation (see LED RDY).
Cyclic communication is taking place.
Cyclic communication has still not been fully established.
Possible causes:
- The controller is not transmitting any setpoints.
- In isochronous mode, the controller did not send a Global Control or it sent a
defective Global Control (GC).
PROFIBUS master is sending incorrect parameter assignment/configuration
Cyclic bus communication has been interrupted or could not be established.
