Chapter 3 Initial Operator Interface Configuration
Information Windows
Certain operations communicate directly with the drive, which may cause a
performance lag. The interface will display status messages relating to the ongoing
operation.
Accessing/Writing to Drive
On initial start-up, the interface knows little about the drive. At each screen, the
interface receives and stores information from the drive, and displays the message,
“Accessing Drive...”. The interface will not accept user input until it completes the
access task. Using the same screen for the same data will then be faster, since the
interface can access locally-stored data.
Optionally, you can download the complete database to the interface to eliminate
the initial access delays. If uninterrupted, the interface automatically downloads
the database on power-up, or during periods of inactivity.
Some operations must write information to the drive, during which the interface
displays, “Writing to Drive...” The interface does not accept user input until the
task finishes.
Communication Errors
Many things might disrupt interface communication with the drive. In the event
of a disruption, the interface provides a status window, and will not accept further
user input until it completes the current task.
The “Communication Error” message has two forms. If the interface is already
“Accessing Drive” or “Writing to Drive”, then the error message appears in the
current window. For screens displaying real-time data from the drive, such as the
'Top Level Menu”, a new window displays the “Communication Error”. Two
examples appear in
Figure 12 .
