Building object tree

General 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 in the Communication
structure:
• You can right-click the object to which you want to add a child object. Then select
New > Object type group > Object name, for example New > SNMP > SNMP
OPC Server.
•
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. SNMP OPC Server
3. SNMP Subnetwork
4. SNMP IED
5. Logical Device objects
6. Logical Node objects
7. Data objects

Adding Gateway object

To start building the object tree, add a Gateway object in the Communication structure
by selecting the project name, right-click it and select New > Communication > Gate-
way.
Description
An object representing a network device that supports
SNMP protocol.
An object representing a group of functions. Each function
is defined as a Logical Node. A 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.
