In IO redundancy mode, the minimum pulse length is greater than the input delay and
greater than the cycle time + 50 ms.
Redundancy failover time
At an I/O redundancy failover, the update time of the process values or the detection of an edge
transition is delayed once by no longer than this time.
The maximum redundancy failover time of the I/O module is 55ms.
