VEGACOM 557 Profibus DP 37
The meaning of the individual bits is defined as follows:
Status of the inputs (EK):
0 = all inputs OK
1 = input status not available (no inputs configured or VEGAMET not available)
Switching status of the inputs (EK) 1 and 2:
0 = Input contact is open
1 = Input contact is closed
Status of the outputs (RK):
0 = all outputs OK
1 = outputs status not available (no outputs configured or VEGAMET not available)
Switching status of the outputs (RK) 1, 2 and 3 (output 3 corresponds to fail safe relay):
0 = Relay is deenergised
1 = Relay is energised
