Virtual output port (SEL user program o SEL
system)
7300 ~ 7599 (300)
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
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.
