Cyclic communication is not (yet) running.
Note:
PROFIdrive is ready for communication when the control unit is ready for operation
(see RDY LED).
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.
– To set the bus address for a PROFIBUS node using STARTER, first set the rotary
code switches to 0
dec
– Then use parameter p0918 to set the address to a value between 1 and 126.
– The address is set manually to values between 1 and 126 using the rotary coding
switches. In this case, p0918 is only used to read the address.
