2.4.3.9 Global variables
Dialog window: Formula Editor ▶ Variables
Global variables are client-embracing variables, which are adopted from the
corresponding table of the program part Configuration, where the global
variables can be defined, at the start of the determination and assigned to
the determination. The field Variables of the formula editor lists all Global
variables which are available for the current method, sorted according to
name.
Syntax
'GV.Variable name.Variable name'
Examples: 'GV.TestDate', 'GV.TestTime.VAL', 'GV.Average-
Temp.UNI'
You can select the global variables directly in the formula editor under Var-
iables/Global variables in order to avoid syntax errors.
