Using PML in AVEVA Products
: Defining Variables for Late Evaluation (Rules)
Defining Variables for Late Evaluation (Rules)
The following are used to pass the
name
of a variable into AVEVA E3D™ as part of a stored expression so that the value is taken when AVEVA E3D™ processes the stored expression rather than PML extracting the value at the time the line is read:
VVALUE( !X )
VTEXT( !AString )
VLOGICAL( !Aboolean)
