As usual, ibaPDA continuously acquires data from the automation environment. The stored signals (digital and analog signals as well as text signals) are signals resulting from the configuration in the ibaPDA I/O manager.

• With a time-based HD data store configured in ibaPDA, the acquired digital/analog signals are transferred to the desired ibaHD-Server and are stored there in a time-based HD store.

• With a time-based HD data store with time periods configured in ibaPDA, the acquired digital/analog signals are transferred to the desired ibaHD-Server and are stored there in a time period store.

• With an event-based HD data store configured in ibaPDA, events are created from the defined triggers, transferred to the desired ibaHD-Server and stored there in an event-based HD store.

• With a length-based HD data store configured in ibaPDA, the acquired digital/analog signals are transferred to the desired ibaHD-Server and are stored there in a length-based HD store.

In contrast to the normal data store, the HD data store creates no measured data in the iba format (dat), but sends the stored data to ibaHD-Server which takes the data and writes them in the correspondent HD store.

ibaAnalyzer allows the conversion of HD data into standard iba data files.
