Hello,

I have interesting problem: Sometime Graph 7 sequence freezing (time for actual step is zero). Only one solution for Graph sequention start again is send it to PLC with DB again. I don't understant why I have this problem, because this sequention is very simple and is min. 6 months old wihout any changes (any changes in HW, too).

Thank for support
