Hi guys!
Is it possible to realize a stopwatch in TIA? Like a timer, but it keeps counting time, not to expire?
Thanks a lot!

TONR (retentive timer) or RTM (run time meter) or something more custom?
"in TIA" is only half helpful -- which processor do you use?

S7-1512C-1 PN

Just a simple stopwatch, to tell me how long did some equipment work.

The forum search provides some interesting results for "run time counting"

One such is the example given by user @koenb:

Hi guys!

I found a solution. 

I put a TONR, with a maximum value of 24H and an auto reset or reset button. When 24h will have passed, a counter will count the number of times the 24h limit will have been overdued, this meaning that 1 day will have passed.

For anyone who would need this.
