Number of symbol definitions 1000
Number of times symbol can be used in
commands
5000 (including literals)
Used in common from
any program.
Referenced separately
in each program.
Cleared when the
program is started.
Caution
Variables 99 and 199 are special variables this system uses in operations. Avoid using these two
variables for general purposes.
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.
