Creating and Editing the Redundant OIS Connection - Configuration - P54592-P101-A1 - P54592-P118-A1

If a redundant OIS connection is configured, two connections are established: an active connection and a stand-by connection. Siveillance Control communicates with the subsystem through the active OIS connection. The active connection allows to receive messages from the subsystem and send commands to the subsystem. The stand-by connection and the active connection are both monitored. Connection faults of both connections are displayed in Siveillance Control. If the active connection breaks, the inactive connection is automatically activated, the former active connection will get the inactive connection once the issue is resolved. If a connection breaks, you need to investigate further.

Creating redundant OIS Connections in Engineering Client

• The license for redundant OIS connection has been imported. For more information, refer to: License Import in Configuration.

• On two separate servers, OIS has been installed and all connected subsystems are configured the same way in OIS Tools.

• The Administration perspective is displayed.

• For both OIS installations,OIS Tools is displayed in the Web browser.

1. In the Administration tree, right-click System > External Systems and select Create Redundant OIS Connection.

2. Enter a name with which the user can identify the redundant OIS connection.

3. Under First Connection, enter the connection address and secure token of the first OIS installation.

4. You can find the connection address in the engineering unit configured under the gateway in the OIS Tools.

5. You can find the secure token under Settings > Certificates in the OIS Tools.

6. Under Second Connection, enter the connection address and secure token of the second OIS installation.

7. Click Finish.

8. Continue with the data points import. For more information, refer to: Importing the Data Points File in Configuration.

9. The changes made on the engineering server are not automatically available on the runtime server and need to be activated first. Continue with activating the data. For more information, refer to: Data Check and Validation in Configuration.

Editing Redundant OIS Connections in Runtime Client

This configuration is only necessary if you want to use the OIS connection simultaneously from engineering client and runtime client.

• The Administration perspective is displayed.

• OIS Tools has been installed.

1. In the Administration tree, open the redundant OIS connection under System > External Systems.

2. Select the first OIS connector.

3. In the Object Properties view, click Misc > URI.

4. Replace the connection address of engineering client with runtime client. You can find the connection address in the runtime unit configured under the gateway in OIS Tools of the first OIS installation.

5. In the Administration tree, select the second OIS connector and replace the engineering connection URI with the runtime connection URI of the second OIS installation.

6. To start receiving the messages, switch on the OIS component under System Tree. For more Information, refer to: Subsystems and Integrations in Operation.
