7.4.2.4 Trigger
The calculation monitors whether an analog signal exceeds and/or falls below a limit
value. You can monitor two limit values with the function. Use the hysteresis to prevent
signal noise from generating multiple trigger pulses. As soon as a limit value is
exceeded and/or undershot, a pulse (lasting 1 ms) is outputted on the trigger flag. As
long as the signal remains within the hysteresis, no further pulse is triggered. The Hys-
teresis is below the limit value in the case of Above threshold and above in the case of
Below threshold. In Above or below threshold mode the hysteresis is both above and
below (example 2).
If the source signal is invalid, no pulse is generated. The values for limit value and hys-
teresis are not checked.
