Use integer or double integer variables with add block. Count upp with one second pulse when system in running.

Another method is save ton-timers value, when system stops.

OK Lare but my quastion is how to save this TON-TIMER VALUE?????What i must to do ?

 

[Lare]

On some PLC you can write to ton-timers elabsed time variable. Not sure is it even possible with schneider plcs.

But easier is to use int or dint type variales. If you need time format, you can change to it after you have counted time.

Hey guys i have some solutions but it is at ladder diagram.Can you help me to convert to CFC this http://static.schneider-electric.us/docs/Machine Control/OEM Solutions/8000DB0706.pdf Thanks for your time !!!!

they are talking about retentive timers, have a look at retain variables.

a glimpse of it, use a variable in global retain and give it every second a pulse adding 1 to the hourcounter %MW69 for example and this var is declared in var global reatin.
just type the varname (hourcounter) and fill in the reatin check mark etc.
this way you make your own hourcounter
another way is to use www.oscat.de (english library for your schneider)
.
