Standard Mode
In the programming system, the combination of direct selection and
control function can be programmed for function keys and for soft keys.
Only the press codes of the keys should be evaluated in this mode of
operation. This is because, depending on the length of time the key is
pressed and the nature of the assigned mask, the stop code may have
already changed!
5.11.1 Direct Selector Keys
Direct selector keys are function keys programmed to directly call up a
specific mask. Pressing this function key thereby allows you to directly
change to another mask.
This change of mask is not possible if the data release has been
requested (status LED in the Data Release key is flashing or lights up)
in a mask without automatic data release.
Direct selector keys allow speedy and convenient operation.
5.11.2 Function Keys in the Controller
In addition to programming function keys as direct selector keys, they
can be programmed to carry out a function in the controller. To do this,
instead of assigning a mask change to a function key, assign it the
symbolic name of a controller variable in the application description.
When you press the key, it can set or reset the variable, and the same
functions are assigned to it when you release the key. If you assign the
set function to the key, the value entered is assigned to the data type.
In other words:
If the digit 1 is entered as the value:
• A flag bit receives logical 1
• A flag byte receives the value 01h
• A flag word receives the value 0001h
• A double word receives the value 00000001h
For values greater than 1, you must specify at least a byte address for
the variable.
5.11.3 Softkeys
Soft keys are function keys that carry out a different function, depend-
ing on the mask in which the appear. The current function of a soft key
is described in the current mask. In this context, you can use images,
background images, selection images, static texts, and selection texts.
