This function block monitors the relevant safety guard. There are two independent input param-
eters for two switches at the safety guard coupled with a time difference (MonitoringTime) for
closing the guard.
The function block requires two inputs indicating the guard position for safety guards with two
switches (according to EN 1088), a DiscrepancyTime input and Reset input. If the safety guard
only has one switch, the S_GuardSwitch1 and S_GuardSwitch2 inputs can be bridged. The
monitoring time is the maximum time required for both switches to respond when closing the
safety guard. The Reset, S_StartReset, and S_AutoReset inputs determine how the function
block is reset after the safety guard has been opened.
