An error is detected if the time lag between the first S_GuardSwitch1/S_GuardSwitch2 input
and the second is greater than the value for the DiscrepancyTime input. The Error output is set
to TRUE.
The function block detects a static TRUE signal at the Reset input.
Error and reset The S_GuardMonitoring output is set to FALSE. If the two S_GuardSwitch1 and S_Guard-
behavior switch2 inputs are bridged, no error is detected. To leave the reset error state, the Reset input
must be set to FALSE. To leave the discrepancy time errors, the inputs S_GuardSwitch1 and 2
must both be set to FALSE.
