I've been searching the forums for hours and I've found many things to try but just haven't found the right answer yet. I have a running PLC 5 that has several remote racks off RIO. Rack 3 has a 16 channel DI card, a 16 channel DO card, and a 4 channel analog output card (OE4).
My question is: On rack 3 I can address the DIs as if they were connected directly to the PLC using I:30/0-17, the DOs are using O:31/0-17. How do I address the 4 channel analog card? Can I write directly to it? I tried with no luck. I read that I have to use a BTW. If that's the case then what should the R/G/M be? Would the rack be 3 or 003? Then I'm confused from there. Group 2? Module 2? I have yet to find a good manual that specifically explains what those mean. I don't know that I can attach the program itself but I can take screen shots of whatever is needed. Again from researching I read that I should look at the switches and S:2/11-S:2/12 are set to 1 Slot.
Any help would be great. Thanks.
