A Third Party OPC client can only connect to a ClearSCADA server if it has the ClearSCADA Data Components installed. Once installed, the Data Components will handle the communications between the Third Party OPC client and the ClearSCADA server.
By installing the Data Access Components, you allow the Third Party OPC client to communicate with the ClearSCADA server using TCP/IP protocol. This means that DCOM is not used and so the problems commonly associated with DCOM on OPC systems are avoided DCOM Issues.
NOTE: The Third Party OPC client also needs to have a valid ClearSCADA connection Configure the Third Party OPC Client - System Connection and OPC license.
