14.1.22.2 Function 2: nIn1 > nIn2
This function serves, for instance, to implement the comparison "actual speed is higher
than a limit value" (n
act
> n
x
) for one direction of rotation.
[14-8] Function 2: Switching performance
Functional sequence
1. If the value at nIn1_a exceeds the value nIn2_a, bOut changes from FALSE to TRUE.
2. Only if the signal at nIn1_a falls below the value of nIn2_a - hysteresis again, bOut
changes back from TRUE to FALSE.
