5. Alphanumeric fields
By the pilot device
The connected device changes a variable field to input mode by writing
its number in a word in the dialog table. The number of variable fields can
be displayed in the XBT L100• using the Display/Number of fields
menu.
First, the application program of the connected device should
ensure, again via the dialog table, that the application page where
the field appears is actually being displayed. Otherwise there is a
risk of selecting a field on another page.
In return, the display writes the number of the field being completed in a
word in the dialog table (see chapter C, section 4. Dialog table, Page
53).
Specific feature of this type of selection:
The operator cannot select another variable field until he has completed
the one requested by the connected device (MOD key inactive).

When a field is in input mode, the whole field blinks and three input
methods are available: accelerated incremental input, thumbwheel input
or direct input.
- Accelerated incremental input: The total value of the field is increased
or decreased by pressing keys and .
- Thumbwheel input: First, the digit to be modified is selected and it
starts blinking when keys and are pressed. (These keys are
managed in the same way as a "drum". This means that on reaching
one end
of the variable field, you go back to the other end). Next,
when keys and are pressed, the digit values are displayed
in one direction or the other (these keys are also managed in the
same way as a "drum").
