Trigger Functions of the Analog Trigger
For a trigger detection, the trigger blocks compare the applied actual value (measured value) with the config-
ured trigger criteria (threshold values). The appropriate trigger starts a fault record in the fast-scan and/or
slow-scan recorder with the detection of a trigger criterion (exceeding or dropping below a set parameter
threshold value). The threshold values are checked on a half-period cycle for all measured values.
