Functions without Ladder elements
VisiLogic contains
functions that are not
represented by Ladder
Elements. You can
perform these functions
by storing values into the
System Integers listed
here.
To select the function
type, first store the
number of the function in
SI 140, then use SI 141 to
146 to contain the data to
be used in the function.
Note that when you run
Test (Debug) Mode, the
current value in SI 140 will
not be displayed.
