Ive just started learning about RIO lately, I have no expierence with them. I do have a basic undestanding how it works,but my question is "If I have 5 remote racks in the plant and I want to add one more, do I have to add it to the end of the cable or can I add it in the middle. I'm asumming I cant address it as though it was the last rack on the network." I did just that and cant get the 1747-asb to communicate, it goes thru the set-up and then shows no-com? I dont want to have to change the adressing of the next two racks, but it starting to look that way. Bear with me i'm trying to work thru this, I think I have the BTR,BTW figured out but I know I'm missing something.
