Configuring data objects

General about configuring data objects

You can configure data objects either in the Object Properties window or in the Cross
References window.
The actual configuration in Object Properties window by using SAB600 is performed
as described in 3.4.1, General about configuring objects.
To configure the data objects in Cross References window:
1. Select the IED object in the object tree and right-click it.
2. Choose the Cross References window from the context menu.
3. Change the values in cross references table by simply writing the new value in table
cell with the desired property.
4. Finally, click Apply to save the changes.
The parameters are stored in Object properties in SAB600 (see the tables for each data
object type).
