Control via PROFIBUS
Diagnostics LED "COM (PROFIdrive)"
The PROFIBUS diagnostics LED is located on the front of the Control Unit. Its states are
described in the following table.

Description
----- OFF Cyclic communication is not (yet) running.
Note:
The PROFIdrive is ready for communication when the Control Unit is ready for
operation (see LED RDY).
Green
Continuous light
Cyclic communication is taking place.
Green 0.5 Hz flashing light 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).
Red
0.5 Hz flashing light
PROFIBUS master is sending incorrect parameter assignment/configuration
Red
2 Hz flashing light
Cyclic bus communication has been interrupted or could not be established.
Setting the PROFIBUS ID number
The PROFIBUS Ident Number (PNO-ID) can be set using p2042.
SINAMICS can be operated on PROFIBUS with various identities. This allows a PROFIBUS
GSD that is independent of the device to be used (e.g. PROFIdrive VIK-NAMUR with Ident
Number 3AA0 hex).
● 0: SINAMICS S/G
● 1: VIK-NAMUR
New settings do not become active until after POWER ON, reset, or download.
Note
Totally Integrated Automation
The advantages of Totally Integrated
Automation (TIA) can only be utilized when selecting
"0".
