When you call up the network structure graphic, the screen is normally divided into two sections:

The display area shows the active portion of the navigation area.

• You can enlarge or reduce the size of the active portion with the function keys F5 and F6.

• You can collapse either the activities inside a frame or the frame itself.

In the navigation area you can see the entire network or standard network.

• The active portion shown in the display area is enclosed by a frame.

• To view another section of the network in the display area, move the frame within the navigation area.

• Change the size of the display frame by dragging the frame to the required size in the navigation area.

• Subnetworks or standard network alternatives are displayed in another frame.

There is a toolbox above the display area containing the most important functions for working in the network structure graphic.
