I'm a Fanuc Greenhorn and need to add some push buttons and lights to a R-J3 controller. The process I/O board has a CRM2A port which I believe is the port I need. I bought the connector and soldered it to the pins I think I need. Keeping in mind I'm going off a European manual and am not sure it is the same as the model I have. I'm pretty sure it is correct judging from post I've read off this site. I'm not getting any response from the I/O screen when I flag my I/O. I'm looking in the UOP screen.
Any help would be much appreciated.
