function of NC/PLC variables. A variable, which makes use of a toggle field extension, is
read-only.

displayed in the input/output field. Default value 15 is entered in system
variable DB90.DBB5. If the value saved in system variable DB90.DBB5
changes, then the displayed text number $(85000 + <DB90.DBB5>) is
recalculated in response to every change.
Parameters: Variable type Type of variables specified in the system or user
variable
Text number Number (basis) of the language-specific text valid as
the basis number.

System or user variable (offset) via which the final text
number (basis + offset) is displayed.

Variable toggle field
It is possible to assign a variable toggle field to a dialog element, i.e., when the toggle key is
pressed, a value configured in a CHANGE method is assigned to the variable.
An asterisk * is entered in the Limits or Toggle Field property to identify a variable toggle field
when a variable is defined.
Example:
DEF VAR1=(S/*)
