Posted 2 Mar 2016 That's a fairly old processor (the System 2003 line came out in the mid 90's, despite the name implying it came out in 2003), but it might support OPC, which would work with basically any HMI. If it doesn't support OPC, you could do a .NET HMI and use B&R's free API to talk to it. I assume you have the original PLC program (B&R HMI program is part of the PLC program) and a copy of Automation Studio so you know what all the variable names are and whatnot. I'm curious why you would go through the time and expense to replace the B&R HMI on such an old PLC line. If the HMI broke, you can just slap on a new one and it will upload the HMI from the PLC.

Posted 14 May 2016 B&R Automation Net supports OPC for the CP474. You can use any HMI Software that supports OPC Share this post Link to post Share on other sites
