Hi.

I tried to make a new grafcet in another setup and that did run. There's nothing wrong with the Proview installation then.

I'm trying to figure out how to structure the plc code even though I am still in the learning phase. Maybe that's to ambitious. Attached is the configuration for the project. The grafcet that wont run is in the Boiler_PLC program. I compared mine attributes with the attributes in your attachment and they are the same.

I did notice an error message in the console window appearing at different times in the creation process, f.ex. after updating an order in the grafcet when the attributes window is closed.
The message is '(wb:2080): GLib-CRITICAL **: Source ID XXXXX was not found when attempting to remove it'
But i got this message when I made the new grafcet that did work,

The loop counter is ticking.

Hi.

I started from scratch and now everything works fine.
Somehow I must have messed up something in my first run.
Would have been satisfying knowing what caused this problem, but won't put much more effort in that. Too much else to get into.
