To configure an object tree:
1. Build an object tree by adding the necessary objects to the object tree, see
3.3.1, General information about building object tree and 3.3.5, Adding data objects
using Cross-References function.
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 Serial Slave OPC Client object
and its child objects, such as channels, devices, and data objects. Indentation is used
to indicate the parent-child relationship between the objects.
2. Configure the object properties in the communication structure, see 3.4.1, General
information about configuring objects.
The following table describes the objects shown in the object tree (Figure 3.2-1).
