A got a larger project but this very small example makes it clear. I have a button, and after it's clicked a lamp should flip on and stays on, and when the mouse-button is released it should stay on. When I try that in the PLC_PRG it works, but when I change it to a function block (seet attched demo proj) it isn't. I'm fairly new to PLC programming but are very experienced C# engineer, but this goes above my head...

Did you ever find a solution to this? I am having the same issue but using TLS connection.

You could use the Modulo function to get the minute part from the total minutes: Minutes := TotalMinutes MOD 60;

Your function block instance is not called, so the code is not executed to set the light on when the button is pressed.

Only logged in to agree with the above. So counter intuitive. Why does an associated action force the variable when the step it is associated to is not active? Makes no sense at all, is terrible to debug and costs a lot of time. Such as shame.
