Parameters
Function
If a new value is received during the delay time, the delay restarts and the old value is discarded.
The timer resets to zero and restarts (Retrigger).
Once the delay time has elapsed, the last input value is updated to the output value.
When enabling the delay using the checkbox, note the following:
•
If input D is not linked, the delay time will automatically be set to 0.
Use cases
•
Delayed transmission of scene values.
•
A motion sensor is monitoring corridor lighting. As soon as the sensor detects a movement, the
lighting in the corridor is gradually switched on (e.g. every 500 ms).
•
Monitoring receipt of cyclical telegrams.
Bus voltage failure, download and restart
In the event of bus voltage failure, the timer stops and the input value is discarded. Therefore the output
sends no value on restart.
Other
Unlinked inputs are treated as if they did not exist.
