The configuration work can basically be divided into two separate tasks:
1. building an object tree, and
2. configuring object properties.
First, you need to build an object tree. This is done by adding objects to the object tree,
see 3.3.1, General about building object tree .
Figure 3.2-1 shows an example of how the object tree may look like after it has been
built. In the example tree you can see the Modbus OPC Server object and its child objects
like channels, devices, and data objects. Indentation is used to indicate the parent-child
relationship between the objects.
After you have added the necessary objects to the object tree in the communication
structure, you need to configure them, see 3.4.1, General about configuring objects.
