I need to add a button to my plasma screenset, i want to be able to toggle the "M1 optional stop" on and off, with an LED as well to show status.

I think the button is 177 and the LED is 65??

Is it simply a matter of adding those controls and assigning them to those features or am i missing something here ??

I find machscreen awkward to use so wanted to go in fully armed with what i need to achieve

Yes it is that simple. You also need to name the button.

(;-) TP

Brilliant, thanks for that
