I'm having trouble with a Allen Bradley 9/230 communication problem. This is a 1998 control for our JetEdge waterjet.
According to the operators, it was uploading files fine, & then it wasn't. We use the Allen Bradley ODS for communicating with the control, when I try to download a program to the control, I get a timeout error. I've rung out the cable & it appears fine.
When I checked out the monitor function on the control, it states that port "B" is busy. But if I'm not sending or receiving, it shouldn't be busy, should it?
Does anyone know of a way that I can cancel whatever is tying up the port? I've tried calling JetEdge, but they haven't used this control for so long, no one seems to know anything about it.
