Chapter 5 Detailed Descriptions of I/O Modules
After changing the hysteresis value, an active hysteresis remains active. The new hysteresis value is
actived during the next hysteresis event.
The behaviour of the status bit for hysteresis = 0 (hysteresis deactivated) and hysteresis = 3 is shown
in the following diagrams (legends describe the behaviour for hysteresis = 3)::
Operating principle of the Hysteresis with Counter Value ≥ Comparison Value
1 Comparison condition met ➝ status bit is set and hysteresis activated
2 Comparison condition not met, leaving the hysteresis range ➝ status bit is reset
3 Comparison condition met ➝ status bit is set and hysteresis activated
4 Leaving the hysteresis range, the status bit remains set because the comparison condition is still
met
5 Comparison condition no longer met but hysteresis still active ➝ status bit remains set
6 Comparison condition met, hysteresis still active ➝ status bit remains set
7 Leaving the hysteresis range and comparison condition met ➝ status bit remains set
