Operator Interface Chapter 3
The window for the "Communication Error" can take on two forms. If a window
has already been displayed showing "Accessing Drive" or Writing to Drive", then
the communication error message will be added to the window already in use.
Some screens constantly read from the drive in order to show real-time data. An
example of this is the 'Top Level Menu’. When a communication error occurs on a
screen showing real-time data, a window is opened showing a box around the
"Communication Error". Two examples of this are shown in
Figure 75 and
Figure 76 .
In both cases, once communications has been re-established, the information
window will be removed and the operator interface will return to normal
operation.

Languange Changing
When the language used by the drive changes, (either via the operator interface or
an external device), the operator interface must do considerable work. The
database strings are all invalidated, the character set for the server is changed and
all strings used by the operator interface are linked to the new language. During
this possibly lengthy process, the “Language Changing ...” message is displayed.
