Building object tree

General information about building object tree

The object tree is built in the Communication structure of SAB600, see Figure 3.2-1. It
is built by adding objects in a logical order starting from the Gateway.
You have several possible ways to add objects to the object tree:
• You can right-click the object to which you want to add a child object. Select New
> Object type group > Object name , for example New > IEC103 > IEC103 >
IED.
• You can right-click the object type and select New > New. A New Object window
appears. Select the object type you want to add and click OK or double-click it.
•
You can copy the object.
Add the objects in the following order:
1. Gateway
2. IEC103 OPC Server
3. IEC103 Channel
4. IEC103 Device
5. Logical Device objects
6. Logical Node objects
7. Data objects
For information on building a substation structure, refer to COM600 HMI Configuration
Manual.
Description
An object representing a physical communication channel.
You can define up to three channels per OPC server.
An object representing a physical device. You should not
have more than 30 devices per each channel.
An object representing a group of functions. Each function
is defined as a Logical Node. A physical device consists
of one or several LDs.
An object defined by its data and methods. LN is the
smallest part of a function that exchanges data.
Data object is an instance of one of the IEC 61850 Data
Object Classes such as Single point status and Measured
Value. Depending on the class, each data object has a
set of attributes for monitoring and controlling the object,
e.g. value, quality, and control.
