| *tET* | TIME      |             |               | Time difference between the minimum duration and the duration of the pulse at *xQ* |

### Function description

#### General

At the pulse output *xQ* after a rising edge at the binary input *xIN* a pulse with a minimum duration *tPT* is generated.

#### Time output *tET*

When the pulse output is active *xQ* the time difference between the minimum 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 displayed.
