Used in common from any
program.
Referenced separately in
each program.
Cleared when the program
is started.
x
Variables 99 and 199 are special variables this system uses in operations.
Avoid using these two variables for general purposes.
x
The values in the table represent ranges that can be processed by software.
Items that require physical devices, such as I/O ports and functions relating
to axis number and SIO, will be determined by possible combinations and
models of commercial boards, etc., available for each device application.
