Detailed Description of I/O Modules 224
After changing the hysteresis value, an active hysteresis remains active. The new hysteresis
value is active during the next hysteresis event.
The behavior of the output for hysteresis = 0 (hysteresis deactivated) and hysteresis = 3 is
shown in the following diagrams (legends describe the behavior for hysteresis = 3):
Figure 118: Operating Principle of the Hysteresis when Counter Value ≥ Comparison
Value, Pulse Duration 0
1.
Comparison condition met
➝
output is set and hysteresis activated
2.
Comparison condition not met, leaving the hysteresis range
➝
output is reset
3.
Comparison condition met
➝
output is set and hysteresis activated
4.
Leaving the hysteresis range, the output remains set because the comparison
condition is still met
5.
Comparison condition no longer met but hysteresis still active
➝
output remains
set
6.
Comparison condition met, hysteresis still active
➝
output remains set
7.
Leaving the hysteresis range and comparison condition met
➝
output remains set

➝
output is set and hysteresis activated
