Terminal Menu Hierarchy Chart
The screens of the terminal are used to form a menu driven system to access the various operations in
the drive. The hierarchy of this menu system is shown in Figures 88 and 89.
What does it show?
The chart shows the relationship between screens and a particular operation. It also shows the
path to reach a particular screen. This chart does not introduce you to the use of the terminal,
however is useful as a reference to the preceding material.
How do you read it?
Each of the boxes represent a screen and contains the screen name. From a particular screen, a
downward arrow shows what other screens can be displayed and which function key is required to
move to that screen. Pressing exit [F10] on the screen will move you in the opposite direction,
returning you to the screen from which you came.
A lateral arrow shows to which screen you can move by pressing the [enter] key while making a
selection. Again pressing exit [F10] on the screen will move you in the opposite lateral direction,
returning you to the screen from which you came.
Some of the operations have screens in common. These are shown only once on the diagram.
Their use is indicated by symbols inserted into a circle. For example: The ACCESS screen is
displayed from the MAINMENU by pressing the [F10] key. In this location (marked by an *), the
operation of the screens ACCESS and PASSWORD CHANGE are shown in their entirety. These
operations are also available from the MODIFY PARAMETER screen and SETUP screens by
pressing the [F8] key. At these locations, the operation of screens is represented by the symbol
'P', which represents the same flow as previously defined.
For sake of clarity, the soft function key calls to the HELP operation and the ALARMS screen
have not been shown. It is implied that all screens have this ability via the F1 and F6 keys
respectively.
