Defining function
keys
You link a function key to a signal by entering the signal's address according to the
relevant key or by choosing the corresponding function from the selection list. The function
key linked to a signal will be activated according to the function you have specified
when defining the function key.
Only two function keys linked to signals can be activated at the same time. If more than
two function keys are pressed simultaneously, only the two signals that were triggered
first will be activated.
The number of function keys depends on the terminal type.
You can define function keys in two ways:
Globally
Locally
Global definition
Global function keys are defined and used in the entire application and apply to all
blocks.
A global definition is always available in run mode if the block displayed on the screen
does not have any local definitions for the current function key.
Global definitions are made under [Functions] / [Function keys].
Local definitions
Local function keys are defined and used for a block.
Local definitions have a higher priority than global definitions.
Local definitions are made under [F keys] in the block header of the current block.
