You can’t directly connect to Win911 using the OPC-COM module. I had to use KepWare, then connect Win911 to Kepware and Ignition to Kepware using the OPC-COM module, you can use OPC-UA to connect to Kepware, but its a few more steps because you have to set up certificates. Also note that the there is a bug with OPC-UA connection dropping out and not reconnecting. I don’t know if this has been resolved yet.
