Operator Interface

The remainder of the screen shows the data from the drive. The presentation of
the data is dependent on the screen. Screens that allow an item to be selected
show the current selection in reverse video. An example of this is shown in

Figure 73

in which the Speed Control group is selected.

Information Windows

Numerous screens require communications with the drive in order to function.
At times, the duration of this activity will be noticeable to you. During this
activity, a special 'window' is used within the current screen to inform you of this
activity. The time required for the activity will vary.

Accessing/Writing to Drive

When first powered up, the operator interface knows very little about the
information in the drive. As each screen is activated, the operator interface
requests information from the drive, which it will store within the operator
interface for future reference. When the operator interface requests information
from the drive, a window is used to display a message "Accessing Drive ...". During
this time, the operator interface will not respond to any user input, until the task
at hand is completed. You will notice that subsequent activation of the same
screen for the same data will be much quicker since the operator interface already
has most or all of its required information.

You can selectively choose to download the complete database to the operator
interface on command, thus eliminating the initial access delays. If uninterrupted,
the operator interface will automatically download the database on power-up, or
during periods of inactivity. Refer to

Database Download on page 162

.

Some screens require that information be written to the drive. During this task, a
window is used to display the message "Writing to Drive...” During this time, the
operator interface will not respond to any user input, until the task at hand is
completed.

Communication Error

While the operator interface is reading or writing to the drive, it is possible for
communications to be disrupted for a number of reasons. If this were to occur, a
special window is used to inform you of this. During this time, the operator
interface will not respond to any user input, until the task at hand is completed.
