Hello,

I'm trying to get the acyclic communication working to a profibus slave but I can't figure out where to find all information to get the ID used for the function blocks below:
RALARM
RDIAG
RDREC
WRREC


Scope Name Type Initial Comment
Return ID DWORD
Input EN BOOL TRUE
MASTER BYTE ID of the DP system
SEGMENT BYTE Number of the DP segment
STATION BYTE Number of the DP-slave(station address)
SLOT BYTE Slot number

The station byte is the slave dp address but where do I find the values for the rest?

I'm running with the EL6731 Profibus master from Beckhoff, see configuration on the attached picture.

/Martin
