What I’d like to accomplish:  
Either in Auto mode, or in both Auto/Manual, disallow controls linked to I/O from changing the state of the connected controller I/O.

Why setting them to ‘disabled’ in the properties is not good enough:  
The text description of the ‘LED’ control is grayed out to a degree that makes it **_very_** hard to read. If only the ‘LED’ icon was dimmed, but the text remained black, then that would work.

Is there a trick that could be used to keep users from setting I/O during Auto mode? Making a panel overlay the screen with a transparent back-color is not allowed. I haven’t figured out any other hacks to accomplish this.

Thanks

Have you tried changing access rights on the signals in the robotcontroller?  
There you can block signals from being changed in auto or/and manualmode.  
But still allow rapid to change signal states.
