In the Sparkplug B devices node, the signals transmitted in the DATA messages can be selected for the Edge Node and the other devices.

Buttons for the configuration of the devices:

Send only changed values

Each NDATA/DDATA message contains only the signals that have changed when this option is enabled.

Use alias for DATA messages

Instead of the signal reference, the alias number is used in NDATA/DDATA messages. The NBIRTH/DBIRTH messages contain the signal reference together with the alias.

Use raw data type in DATA messages.

Usually ibaPDA writes signal values using float or double value formatting. By enabling this option, the original value format is used (e.g. INT16 or DWORD). This can be useful for bitmapped values. But by using this option, the signal values will disregard any scale/offset option selected.

Meaning of the columns:

Active

Here you enable/disable writing a message.

Device Name

Enter an unambiguous name for the device here. The base name EdgeNode cannot be changed.

Metadata

You can choose metadata in the drop-down menu that is to be sent with the message.

Available for selection are: Unit, comment 1 + 2, timestamp, signal name, signal ID. Select the desired metadata with a check mark.

Signal reference

Select what to use as a signal reference from the drop-down menu. Available for selection are signal name, signal ID or signal comment 1 or 2.

Signals

In order to configure the signals that are to be written, select the edge node or the device in the structure tree or click on the <...> button in the Signals column.

In the following dialog, you assign the desired signals to the devices using the storage profiles. See chapter Signal selection.
