Inserting a Group

Organizing Process Variables

The process variables of the OPC server (known as OPC items) are assigned to
groups. You therefore require an OPC group before you can insert OPC variables.
Follow the steps outlined below to create a group and add items to it:

Activity

1.

Enter a group name in the “Add group” dialog box and confirm the window with “OK”. If you do
not enter a group name, the OPC Server specifies a group name automatically:

2.

In the left-hand window of the OPC Scout, an entry is created for the group below the icon for
the OPC Server. Double-click on this group entry to open the OPC Browser. In the left-hand
pane, you will see the hierarchically arranged name space of the OPC variables.

3.

Click on an element of this structure tree. In the middle window, the OPC items defined for this
element are displayed:

4.

Select the OPC items you want to add to the group in the middle part of the window.

5.

Enter the selected items in the right part of the window by clicking on the arrow pointing right.
