I have 1 encoder hooked up to a CTRIO 1A,1B and 1M(24+) and it will not count in both directions. I have it set up as 2 up counters and both work fine, if I switch one to a down counter then that channel will not count. Any suggestions? This machine has been kicking my butt all day, mis-labeled wiring, variable PS's landed together on the same terminals butt splices all over and even some wire nuts inside the cable trays. Appreciate any help.
