| **xTest** | BOOL      |             | FALSE         | Binary test input (FALSE > TRUE) |

### Function description

#### General

At the pulse output *xQ* is after each rising edge (FALSE > TRUE) at the binary input *xIN* and/or at the setpoint / parameter **xTest** a pulse with a duration *tPT* generated (precondition: *xReset* = FALSE).\
\
Each rising edge (FALSE > TRUE) at the reset input *xReset* resets the pulse output *xQ* immediately (= FALSE).\
\
The edge detection (FALSE > TRUE) on the inputs *xIN* or **xTest** has a higher priority compared to the edge detection on the 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).
