10. LC display

The display on the hand-held pendant station is operated in text mode. To display text,
the control system must send information on the type and the content of the display.
Text to be displayed frequently can be transferred to the HBAS at any time after
initialization and saved in the HBAS in a data memory (RAM). These items of text can
then be displayed using a short command (section 10.2.5).
It is also possible to define areas and to assign attributes to them. These areas can also
be displayed with a short command (section 10.2.6).
Controlling the LC display
Each LCD data block that contains a command for controlling the display must have the
LCD identifier byte as the first character.
6CH
This is defined as
An LCD data block can contain several LCD commands, however the block must not
exceed the length of 135 bytes.
