S7 timers

Hi, I have the following line of S7 STL code,


To borrow some terms from Rockwell PLC timers, would this code be performing an AND NOT operation with timer T62's EN bit, or with its DN bit? Or maybe something else? Thanks!

It should be the Q bit, so the output of the timer.

It is a AND NOT of the timer done bit.

If that is the whole code, then the RLO is ON if both the timer bit and the DB bit are OFF.

The JCN is jump conditional if the RLO is OFF
