Offset Name Description
42 PROFIBUS Master Module
Status
Represents the PROFIBUS Master module’s operating status
Bit 2=Application status
0 - Application stopped
1 - Application running
Bit 8=Data exchange (FBRS)
0 - There is no data exchange with any of the assigned slaves
1 - There is data exchange with at least one of the assigned slaves
Bit 9=Slave input frozen/cleared (FBFC)
0 - A slave's inputs in the IN area are cleared if a slave is not in Data
Exchange
1 - A slave’s inputs in the IN area are frozen if a slave is not in Data
Exchange
Bit 12=Reset (RDR)
0 - No action
1 - A reset is requested by the PROFIBUS Master module because a new
database has been downloaded
