Count mode - process output data
The structure of the process output data depends on the module's parameterization.
1 Process output data with parameter values for:
Load value direct or
Load value in preparation or
Reference value 1 or
Reference value 2
2 Process output data with parameter values for:
Function and behavior of DO1/DO2
m = Offset of output data; depending on extension of station and the corresponding fieldbus.
