You can use 7I77 field inputs 1,2,3,4 as analog inputs to read a potentiometer

Sorry forgot to mention I have the 7i97. There are no analog in pins on there unfortunately

A 7I73 is a possibility if you are not using the sserial port expansion

No eBay APP ID and/or Cert ID defined in Kunena configurationIf you were to swap the potentiometers for MPGs then things would be easier. There are potentiometer-format encoders readily available.
MPG encoders play better with other override sources than potentiometers too.

This sort of thing:

The 7I97 can have up to 4 hardware MPG encoder counters

Ah that's great. Will use mpg's then, thanks for the advice!
