Assign...
Possible Values Values from 0 to one less than the "Number of Bitmaps" are valid. If the variable
has a different value, then the index is internally limited to this range. The value of
the connected variable is not changed.
The Assign... button opens a dialog box to select a variable for the Source field. By default, only
variables of suitable types are displayed.
Status
Contains various settings for formatting the field on the screen.
Source
Assign...
Used to input or display the connected variable.
Possible Settings Name of a UINT process variable
Possible Values Bit 0 If 1, the output field is invisible.
All other bits are reserved.
The Assign... button opens a dialog box to select a variable for the Source field. By
default, only variables of suitable types are displayed.
Bitmaps
Provides a table to select bitmaps for this output field. Bitmaps can be added, removed, or sorted in this list.
Number
Bitmap
This column shows the number of the bitmap shown on the right. The connected process variable
under Data Point must be assigned this value to display this particular bitmap.
Possible Settings This column is only used to show that numbering bitmaps can only be altered
by sorting. Numbering always begins with 0 and increases by 1 for each
additional bitmap.
Shows the currently selected bitmap for the corresponding number in the index on the left. Clicking
on a bitmap name opens a selection list where another bitmap can be selected.
Possible Settings Any bitmap in the project can be selected.
Add Adds a new bitmap to the end of the list.

In doing so, however, equal sized bitmaps should be used to obtain an
optimal display of the output field. The background is not deleted when
switching bitmaps for performance reasons and to avoid flickering on the
screen. Therefore, the rest of an old bitmap can remain on the display
when different sized bitmaps are used.
Bitmaps are displayed in their actual size which means the widest or
tallest bitmap in the list determines the size of the output field. Scaling
bitmaps to the same size does not take place and must be carried out in
a graphics program if necessary.
Inserts a new bitmap into the currently highlighted field of the bitmap list. The remaining bitmaps will
be moved one space down in the list (the bitmap numbers will be increased/decreased by one).
Removes the currently selected bitmap from the list. The remaining bitmaps underneath will be
advanced upwards and will receive a lower index number (by 1 per removed bitmap).
Exchanges the position of the currently selected bitmap in the list with the one directly over it (the
bitmap will be moved up one position).
Exchanges the position of the currently selected bitmap in the list with the one directly below it (the
bitmap will be moved down one position).
Preview
Shows the currently selected bitmap in the list so it can be checked.
