As per the original post.
Wonderware, InTouch, AVEVA (all the same thing) have a do not have a good OPC implementation (UA or DA). Only the loopback IP address (127.0.0.0) can be used by AVEVA to address the server. Thus, ANY server software must be on the same machine as AVEVA. This is not the way OPC was meant to work. I have been experimenting with have a copy of Kepserver on the server hardware (Kepserver/server) and additional copies on each workstation (Kepserver/AVEVA/worikstation). The objective is to use the Kepserver/server to communicate with multiple PLCs to collect data via Modbus and then share the data with Kepserver/AVEVA/workstations. This is a lousy way to implement OPC, but I haven't found an HMI that works any better. Does anyone have any suggestions for an alternate HMI?
