To record signals, you have to assign the signals to a topic by using a storage profile of the type Time.

Signal selection for MQTT timebased data store

Either click in the Topics node, in the Signals column of the topic list on the <…> button to access the signal selection dialog.

Or select a topic in the tree structure.

Note
	Additional information about the storage profiles can be found in the ibaPDA manual, part 5.

Select the topic to which you would like to assign certain signals and select a storage profile in the profile list. Set a check mark in the selection fields next to the signals which you would like to assign to this profile.

The Profile properties section displays some information about the configured timebase and filtering of the selected profile.

For the single value formats and “JSON (per signal)”, if you select more than one signal, a separate subticket is created for each selected signal so that the data can be distinguished on the receiving end.

MQTT data stores are licensed per number of written signals. You can find the current number of selected signals in all MQTT data stores at the bottom of the dialog, similar to the number of configured signals in the I/O Manager. The length of the bar corresponds to the licensed number of signals.

In the example above, a maximum of 1024 signals can be written via MQTT data stores. Currently 7 signals are enabled.

Signal selection for MQTT Sparkplug B data store

The procedure for MQTT Sparkplug B data store is basically identical to the MQTT timebased data store. The difference is that the signals are selected in the Edge Node or Devices nodes.

Click in the Sparkplug B devices node, in the Signals column of the device list on the <…> button to access the signal selection dialog.

Or select the Edge Node or a device in the tree structure.

Select a storage profile of type Time as described above and select the signals in the signal tree.
