Thanks and kudos, James and Michael

Just a quick note that my system started acting flakey on Thursday.  We lived with it till today when I had some cycles to see what was up.  Turns out my Lynx PLC finally gave up the magic smoke.  So, I swapped in a cm11 from my junk box.  Xtension happily accepted the cm11 as a plc, but then to keep the gremlins at bay, all I had to do was change the interface setting from the pull down.

Very slick.  No moving units around or any of that.  I don’t think this particular ‘use case’ comes up all that often so thanks for making such an infrequent event so easy to resolve.

FWIW, the log during the interface swap:

I had turned on debug mode to see if anything useful could be found.

 noticed all of the lights were on on the PLC and unplugged it, both ends.

Actually had the cm11 swapped in at this point, It was plugged into the power line, and I had now plugged in the usb end.

edited the interface type to cm11 at this point and the magic happened again:
