Signal monitoring

The signal monitoring detects when the input signal is in an undefined state (unstable state) for too long. The maximum duration for which an unstable state is permitted is calculated from the set filter time multiplied by the parameter value of the parameter Signal monitoring (Index 8704, Subindex 8). The function can also be deactivated with the value "0" via the Signal monitoring parameter. The safety option responds with an input fault if the signal monitoring is active and the maximum duration has been exceeded.
