Function description

General

At the pulse output xQ a pulse is generated after every rising edge (FALSE > TRUE) at the binary input xIN and/or at the setpoint / parameter xTest with a duration of tPT generated (precondition: xReset = FALSE). Every rising edge (FALSE > TRUE) at the reset input xReset immediately resets the pulse output xQ to FALSE). Edge detection (FALSE > TRUE) at the inputs xIN or xTest has priority over edge detection at input xReset (FALSE > TRUE). This results in the fact that, despite simultaneous edge detection, a pulse with a duration tPT is generated at the output. xQ The setpoint / parameter xTest is cyclically deactivated (= FALSE).
