Definitions

The "Definitions" tab is device-dependent and contains definitions (names for fixed values) that are fac-
tory-set or created by the user. The "User-defined" (empty) and "Texts" folders are available per default.
Depending on the configuration (setup program), further folders with the designation "Process screen x"
(x = number of the process screen in the setup program) are used.
User-defined settings
The folder "User-defined" contains definitions created by the user in the ST editor. To create a definition,
use the "New" function in the context menu (right-click on "User-defined").
A user-defined definition can be used to assign a name (here: start value) to any value (here: 1), which
is used instead of the value in the ST code. The name should describe the meaning of the value, thereby
increasing the comprehensibility of the ST code.
Another advantage of a user-defined definition is that it can be used several times in the ST code. If the
value is changed, it is not necessary to change the ST code, only the value in the definition.
In the case of a CASE statement, definitions can be used instead of fixed values (constants are not al-
lowed here).
