If an OPC HDA client application (including the DeltaV sample clients) is running on a non-DeltaV workstation, OPC Remote must be installed on the non-DeltaV workstation in order to connect to the DeltaV OPC History Server.
To install the OPC Remote application, run the setup.exe program located in the DV_Extras\OPCRemote folder on DeltaV installation disk #4. The version must be the same as the installed version of the DeltaV software.
To uninstall OPC Remote, go to Programs and Features and select OPC Remote from the list. Click the Change/Remove button and follow any dialogs presented. Connection to the DeltaV OPC Server is not available from the workstation when OPC Remote is uninstalled.
