The following example shows three ibaPDA systems distributed on two networks. Each ibaPDA system sends signal or event data to the ibaHD-Server via a time and event based data store. An HD store is assigned to every ibaPDA side data store on the ibaHD-Server. The historical data of the whole ibaHD-Server can be displayed on any ibaPDA client in the networks. The HD signal display and the event table are used for this purpose.

Every HD store can only store data from one source (HD data store of an ibaPDA system). If several ibaPDA systems write on one ibaHD-Server each HD data store has to write in an own HD store. For the installation of each HD data store you configure one HD store on the ibaHD-Server.

Thus you can write, e.g., data from different plants with separate ibaPDA systems in an ibaHD-Server.
