Creating an object tree

4.3 Creating an object tree
The object tree is built in the SPA OPC Server Configuration Tool (see Figure 4-3). It is
built by adding objects in a logical order to the SPA OPC Server Configuration Tool
starting from the SPA OPC Server object.
There are basicly four ways to add an object to the object tree:
• You can right-click the object to which you want to add a child object.
• You can choose the appropriate icon in the toolbar.
• You can select Edit > Add> Object name.
• You can copy the object from an existing file.
• With signals, it is also possible to add an object in a signal table which appears below
the object tree.
Add the objects in the following order. Note that the SPA OPC Server object exists
already.
1. SPA Line object
2. SPA Device or SPA Rack objects
3. SPA Module objects (with relay object only)
4. SPA Signal objects (For all the possible signal types, see Table 4-1.)

4.3.1 SPA OPC Server object

To start creating the object tree
1. Select File > New in the SPA OPC Server Configuration Tool. The SPA OPC Server
object is created automatically.

4.3.2 Adding SPA Line objects

To add a SPA Line object
1. Select a SPA OPC Server object.
2. There are four ways to add a SPA Line object to the object tree. You can either right-
click the SPA OPC Server object and select Add Line, or you can choose the
appropriate icon in the toolbar. You can also select Edit > Add> Line or copy an
existing object.
