You can assign the following functions to function keys and soft keys:
branch to message level,
select screen,
initiate a print job.
display directory,
modify parameters in online mode.
A password level may be assigned to a function key or a soft key. This means
that you can make functions, such as ”Modify parameters in online mode”,
available only to authorized persons.
If a function can be called in a given situation by means of a specific func-
tion key, the LED assigned to the function key can be turned on by the PLC.
Operator guidance, for instance, can be implemented in this manner.
A bit can be configured in a variable for every soft key. This insures that a bit
is set in the PLC when a soft key is pressed. In this instance, the OP always
transfers the whole variable to the PLC instead of the individual bits and
overwrites the information it contains.
When the key is released or upon a change of display which modifies soft-
key assignment, the bit is reset.
11.2 Self-Defined Screen Hierarchy
The screen hierarchy can be adapted to system-specific requirements and be
modified either in part or in whole. Screens can be removed or added.
Screens can be linked together in random order. The design, sequence of the
link, inclusion in the screen directory and the relevant cross-jump destina-
tions are defined during configuration with ProTool/Lite.
You branch between the different screens by means of soft keys and config-
ured cross-jump destinations. Branching from entries of different screens to
one and the same screen is possible (figure 11-1). Cross-jumps are not re-
stricted to screen level, but can branch to the message level too.
Another feature that is configured is the picture you want to have displayed
on the OP as your start screen.
