Function Threshold

152 2CDC 505 056 D0207 | SA/S
Planning and application
The function threshold monitors a 1 byte or 2 byte value. As soon as this
value exceeds or falls below a threshold value, the output can be switched.
The threshold values can be interpreted as hysteresis values:
Threshold values are hysteresis values
Communication object Threshold
Upper threshold
Lower threshold
Switches output
When the value exceeds the upper threshold or falls below the lower
threshold, the output is switched.
Note
If the communication object Threshold value receives a value, which does
not exceed or fall below any of the threshold values when compared to the
old value, no switching operations are triggered.
During the function Threshold, the Switch Actuator can continue to receive
telegrams that can trigger switching actions.
The communications object Switch as well as the functions scene, preset
and threshold have the same priority and are processed in the order that
the telegram is received.
