When you create a connection between a ClearSCADA system and a Third Party ODBC Client, you need to choose which ClearSCADA system is to be associated with that connection. Each DSN connection can only be used to connect an ODBC Client with 1 ClearSCADA system. If you need to connect the ODBC Client to multiple ClearSCADA systems, you will need to create a separate DSN for each ClearSCADA system.
To associate a ClearSCADA system with a DSN, display the ODBC Setup window Configure the ODBC DSN Settings, then use the System combo box to select the system that is to be accessed.
