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
• 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. Modbus TCP OPC Server
3. Logical Device objects
4. Logical Node objects
5. Data objects
For information on building a substation structure, refer to COM600 HMI Configuration
Manual.
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.
Adding OPC Server object
After the Gateway object has successfully been added, you can continue building the
object tree by adding a Modbus OPC Server object.
To add a Modbus OPC Server object:
1. Select the Gateway object in the communication structure and right-click it.
2. Add a Modbus OPC Server object.
By using the SCL Import function, it is possible to import an entire server's or individual
device's configurations without having to insert them manually. To open the SCL Import
function, right-click the desired object, and select SCL Import.
For more information about the SCL Import function, see COM600 User's Manual.
