Hi Steve,
Yes, I was able to solve this issue. Issue was related to DCOM settings only.Also my account did not have enough access rights for the OPC PHD Server.
1. Did you install the OPC Core Components as instructed in the PCo Installation Guide?
Yes.
2. Did you follow the DCOM configuration as provided by Honeywell?
Now Yes. before, we missed out on few of them.
3. What is the exact PCo version number?
PCo 2.3.1
4. Which version of Honeywell OPC Server is being used?
Not sure about it.
