While trying to follow the YouTube series on "Installing the PI OPC interface", I was unable to locate any version of the OPCInt_xx_xx.exe file on the download center. Is there something I am missing or is it not included in the vCampus subscription? Has it been replaced by the PI_OSIOPC.exe application, which I realize is a server, but thought this server would be used to access data from the PI database from an OPC_client application. It is probably possible to write data using this server, but will it function as a full fledged INTERFACE? If not how do I go about obtaining the interface?
