In certain conditions, we have to make sure operator doesn't move the wrong one.
So we plan to use Stand Still Supervision.
Here the two configurations:
But when we set DSTO0_Rx to low level (or high), we can move robot without error.
Axes_Violation_Stop_Rx don't change too.

Can you tell me where is the mistake?
