Hello all,
I have a lighted switch for cycle start
I would like it to be on in auto and off while program is running and in any manual or mdi mode
What pin would give this behavior?

Thanks in advance

The halui pins can be used to control the light.

Depending on the complexity you desire, this might be a job for the LUT5 HAL component. That can set a defined state of a single output bit (the light) for any combination of 5 input states. (mode-is-auto, program.is-running, spindle-is-on etc etc. )

Which reminds me, I should get round to doing this for my lathe. :-)
I don't think that the amber button does anything at all at the moment.

Feel free to ask about LUT5, it will either be instantly intuitive or completely baffling. Depending on whether you dream in binary or not.

Or you might want to look at the documents for lut5 if you don't dream in binary.
