Hi,

I have problem with IEC timers. I have sequency that controls valves (attachment). It works fine, but when I set PT T=0MS (to skip valve) sequency don´t work. In another project I use same kind of sequency, but with S5 timers, and it works fine (also when PT is 0s).

What I do wrong, or is it just not possible to do with IEC timers?
