Thanks for the reply. The controllers have digital and analog I/O that can be looped back with test plugs. That will likely be the approach for closing the I/O

Thanks for the reply. The controllers have digital and analog I/O that can be looped back with test plugs. That will likely be the approach for closing the I/O circuits. I am aware of systems like Test Complete, but I don't know if they can deploy to embedded controllers out of the box, as you've said.
