6.1.3 System Variables and System Parameters
System variables are pre-defined variables for processing properties or states of the HIQuad X
system in the user program. To define them, they are assigned global variables used in the user
program.
The system parameters are used to configure properties of the controller (only possible in
SILworX). System parameters that can only have the values TRUE and FALSE are also
referred to as switches.
System variables and system parameters are defined at different project levels. The system
variables and parameters are configured in SILworX, either in the Properties dialog box of the
corresponding structure tree node or in the detail view of the Hardware Editor.
