After you select data items in the
I/O Mapping window, click
Update application. Control Expert creates the following data objects for each BMENOP0300 module in your project:
-
a DDT located variable structure, including:
-
a Device DDT unlocated variable structure that follows the IEC 61850 data model:
Module → IED → DataModel → LD → LN → DO → <SDO> → DA
You can access the data stored in variables using the dot addressing notation of the IEC 61850 data model, for example: “Module.IED.DataModel.LDevice.LNode.DO.DA”.
Working with Device DDT Variables
In the Variables tab of the Data Editor window, the Type column displays values as follows:
-
The top-most node displays the module name.
-
Leaf (or end) nodes are of the data type, and point to the located variable identified in the Value column.
Working with Located Variables
Control Expert creates unlocated variables for each data attribute mapped in the
I/O Mapping window. Click the
Variables tab of the
Data Editor to view the located address of each variable.
The IEC 61850 data model and Control Expert
support different collections of data types. When Control Expert creates new located variables from IEC 61850 data attributes, it assigns each new variable a data type supported by Control Expert.
