Associate a Third-Party ODBC Client - System with a Data Access License

Third-party ODBC client connections require a license in order to connect to Geo SCADA Expert. There are two types of licensing available:

• Client licensing—The third-party client is associated with a license file provided by Schneider Electric. The content of the license file defines:
  • The amount of time for which the client can connect to systems via the third-party ODBC client - system connection. When this time period passes, the license expires and a new license will be required
  • The versions of Geo SCADA Expert to which the ODBC client can connect via the third-party ODBC client - system connection
  • The number of Geo SCADA Expert systems to which the ODBC client can connect.

    If a client license is to be used, the client licensing feature needs to be enabled for the connection (see Enable or Disable Client Licensing) and you will need to associate the client with a license file. If the license file is invalid or missing, the client will attempt to use server licensing instead.

    The settings for your client license are determined when you purchase Geo SCADA Expert. If you contact the sales representative that sold the product to you, they will be able to provide additional detail about the specific limits of your license.

• Server licensing—The third-party client uses one of the server’s licenses. Each server is allocated a pre-determined amount of data access licenses which can be used by clients. For example, if a server has 20 licenses, it can allow up to 20 clients to connect to Geo SCADA Expert using one of the server licenses. Each client that is not using client licensing uses one of the available server licenses. If there are no available server licenses, clients without client licenses will not be able to connect (until some of the server’s licenses become available again).

  If a client has a client license, this is used in preference to a server license. If the client license file is missing or corrupt, a server license will be used instead (even if the client licensing feature is enabled).

  If the client licensing feature is disabled, server licenses are the only licenses that can be used.

If you have enabled client licensing, you will need to associate the third-party ODBC client - system connection with a client license file:

1. Access the Geo SCADA Expert Client Configuration window (see Display the Geo SCADA Expert Client Applet).
2. Select the third-party ODBC client - system connection in the list of connections.
3. Select the Licenses button to display the Client Licensing window.
4. Use the browse button next to the License File field to browse to the .lic license file supplied by your Geo SCADA Expert vendor. Select the .lic file, then select the OK button to close the browse window and confirm your selection.

   

   You will see that the details of the license are shown in the fields on the Client Licensing window. Your third-party ODBC client will be counted against the Data Access Systems limit. So, if your license has a Data Access Systems limit of 10 and this is the first third-party ODBC client - system connection you have associated with the license, you will be able to use the license for a further nine third-party ODBC client - system connections.

5. Select the Apply button to instigate the license settings.
6. Select the OK button to confirm your choices and close the Client Licensing window.
7. Select the Close button to exit the Geo SCADA Expert Client applet.

If the connection has been correctly configured, and the network is healthy, your ODBC client should now be able to access Geo SCADA Expert.
