3.7 Description of the Data Unit for Online Frames
The display must be configured with the PC software (define character
sets, graphics, texts, variables and macros). The individual elements in-
cluded in the configuration which is uploaded to the display can then be
used by the frames described in this chapter.
The display is delivered with a pre-programmed default configuration.
However, you can create an individualised configuration for your own
application and upload it to the display unit with the PC software. The
existing default configuration is overwritten in the process.
All indices are 0-
based, i.e. “000” is transmitted in order to query the first
text. The position 0 / 0 (x / y) is the upper left-hand pixel at the display
unit. All variables, graphics and texts are written to the display starting at
the selected x and y coordinates, and then proceeding down and to the
rig
ht. The display’s physical limits may not be exceeded during this pro-
cess (otherwise no display appears).
Note: All texts, graphics, variables, character set and bargraphs
are 0-based (even in the PC software)!
Frames which contain no online text (ASCII codes 20
h
through FF
h
, 10
h
and 13
h
), start with the escape character (1B
h
) as the first data byte.
If response frames are used, the next frame can be transmitted immedi-
ately after receipt of the response. However, this may lead to delays in
the execution of macros, moving screen texts and scrolling if the frame
sequence is to fast.
If response telegrams are not used, a pause must be inserted between
the frames as described in chapter
“Online Frame Layout”.
Data bytes included in the data unit must be in ASCII format!
Example, Specifying Position:
... 31
h
32
h
33
h
... must be transmitted for position 123
D
!
(ASCII characters “1”, “2” and “3.”)

ASCII characters!
