i need to read some data from a GE plc.so i connect DeltaV system to the GE PLC using OPC mirror installed in the DeltaV APP station.but i can not see the OPC server of GE plc in the DeltaV system.i have imported the license correctly. could someone give me a hand? or if there is document about DeltaV OPC mirror?
In reply to qingshan6013:
OPCWatchit can be used to connect and browse other OPC servers, but the browse function is an optional feature and may not be supported on some servers.
It's been a long while since I've worked OPC issues, but one thing I'm thinking is that the windows security needs to be set correctly. The Client needs to be able to authenticate. Make sure you have a valid user with valid password on both machines. When you launch OPC Watchit, it is using your windows credentials, and if you are not a valid user, you may not be able to connect to a server.
For browsing, there is also a need to properly register some OPC Dll's. Have you run OPC Remote on the GE server? Maybe some one on this thread can confirm if this would help.
Have you tried loging a call with the GSC? The CTS database likely has this issue documented and you'd get a confirmed solution instead of guesses from "helpful" people like me.
