Hi Soham,
Have you resolved this issue? Tag Browsing errors that you have encountered, when connecting to remote OPC Servers, is almost always a DCOM configuration issue. Please confirm the following:
1. Did you install the OPC Core Components as instructed in the PCo Installation Guide?
2. Did you follow the DCOM configuration as provided by Honeywell?
3. What is the exact PCo version number?
4. Which version of Honeywell OPC Server is being used?
Regards, Steve
