Hi Steve & Swaroop,

       Hooray, now I am able to see all OPC server in PCo.

       My client people reinstalled the Wondarware OPC with new version (Wonderware InTouch 2014).

       I have installed the following things

       OPC Core Components Redistributable (x86)

       OPC UA Local Discovery Server

       SAP PCo   

       In DCOM Settings we have set the Launch and Activation Permissions & Access Permissions to Use default for OpcEnum in Security tab.

       And restarted the OPCEnum Service.

  

       Thank you so much for your inputs.

Regards,

Vijay A.
