Basic settings

For a description of the basic settings see Common and general module settings.

In general, these settings correspond to those of the default OPC client module. Only two OPC servers have to be configured.
Primary OPC server

This OPC server is addressed after the start of the acquisition first and regarded as an OPC server for normal operation.
Secondary OPC server

This OPC Server takes over the data supply in the event that the primary OPC server is disrupted or turned off. This OPC server runs on a different computer than the primary OPC server for logical reasons.
Redundancy

Failover item ID

This setting enables ibaPDA to monitor the correct OPC server.

ibaPDA monitors this item on both primary and secondary OPC servers. If the item value on a server is 1 (TRUE), then ibaPDA will switch to that server. If the item value on both servers is 0, ibaPDA will monitor the primary server.

After the connection to at least one OPC server has been established, select the failover item by using the OPC browser.
