RSLinx and OPC server help


Thread Starter

I have set up RSLINX as an OPC server but cannot talk down to bit level but only can get an I/O word. Can someone tell me if this is possible and suggest what i am doing

I'm not sure, but I think it may depend on your client. I know for certain that you can NOT get bits in RSView32 through RSLinx OPC. However, I found out yesterday that the latest version of RSView Studio Machine Edition DOES let you do this. What I don't know is whether the demo machines I was using yesterday had the same version of RSLinx I have.

Bottom line: call Rockwell Software tech support.

I don't know very well but I think that you need to verify if your Allen Bradley equipment is Controllogix or PLC because the syntax or OPC access level I think is different!
