Wired MPG

[Talyrond]

Hi,
I’m wiring up my own MPG, axis and multiplier selector on an Oak. I’ve followed the wiring diagram for H19, but I can’t get anything out of it. What’s odd is that I can’t get any of the inputs, so INP773 through INP783 to signal on the PLC diagnostics. I can’t even invert/force them with ctrl + alt + I or ctrl + alt + F.
Is that expected behaviour?

Parameters:
218 = 0
348 = 15
349 = 100
350 = 400

Thanks

Julian

Those inputs are too high for force and invert. Only the first 80 have that functionality. Pull the switch inputs to pin 2 (GND) to activate.

Thanks, it's working now. I was putting +5v to the inputs!

For the benefit of anyone else reading this and wondering: inputs on the MPG header are current-sourcing. To activate them, you need to close them to 0VDC.
