We are working with aprox ten year old Fanuc M16i bots with RJ3R controllers. Trying to dope out the config of the Robot I/O - the 8 DI and 8 DO that run through the EE connector to the 6th axis. It appears that the DI are PNP (current sinking), and the DO are NPN (current sinking). This seems strange as all other Fanuc I/O (remote A and remote B) that we have seen is PNP for both DI and DO. Anyone know for sure?
