Function description

General

At the pulse output xQ is generated after a positive edge at the binary input xIN and a subsequent delay time tShift with a duration of tPT is generated. Alternatively, pulse generation without delay can also be triggered by the setpoint / parameter xTest is triggered.

Time output tET

When the pulse output is active xQ the time difference between the target duration tPT and the duration of the pulse at xQ is displayed. When the pulse output is inactive, xQ the value T#0s is always shown.
