Error TwinSAFE-Out
FB-In
Standard-Out
Local-Out
TRUE:
The discrepancy time monitoring of an input pair, or one of the
feedback loops, has found an error. The error reset must be
carried out via the ERR_ACK input of the related TwinSAFE group.
FALSE:
No error was found.
EStopOut TwinSAFE-Out
FB-In
Standard-Out
Local-Out
1 st output channel, the safe state corresponds to a logical 0.
EStopDelOut TwinSAFE-Out
