Contemplating using an OPC client HMI, along with existing WonderWare (WW) HMI, to communicate with a PLC. Is it possible to have 2 different drivers (OPC server and WW InTouch) on the same communication bus (ethernet) and talking to the same PLC (AB PLC 5)?
Not being a WW expert, I am not sure how the InTouch driver works. But I do know that I want to hang an additional HMI station onto the PLC communication network. I want it to be an OPC server, like RSLinx Gateway, and I want to be able to build a small HMI using OPC.
With one machine already running WW InTouch that the customer doesn't want to fiddle with, can I add an OPC server? In other words, can 2 drivers communicate simultaneously with 1 plc?
(At least I believe that is the question. If anyone can give me a bit of direction here I would appreciate it.)
