Global Variables
Global variables are variables that are accessible at all times. There is only one
copy of each global variable. Global variables occur in three ranges: 100-199,
500-699 and 800-999. The global variables remain in memory when power is
turned off.
Occasionally, there have been some macros written for factory installed options
that use the global variables. For example, probing, pallet changers, etc. When
using global variables, be sure they are not in use by another program on the
machine.
System Variables
System variables give the programmer the ability to interact with a variety of
control conditions. By setting a system variable, the function of the control can
be modied. By reading a system variable, a program can modify its behavior
based on the value in the variable. Some system variables have a Read Only
status; this means that the programmer cannot modify them. A brief table of
currently implemented system variables follows with an explanation of their
use.
