Try using the siglib in the Screen Load Scipt instead of the PLC as this works absolutely fine on my machine.

I suggest you substitute mc.mcCntlCycleStop (inst) for mc.mcCntlFeedHold (inst)
in the code for Input63. If this works then something must be mismatched in the Keyboard plugin / Input Signals area for Input62.

By the way, Daz is right, though either way should work .
