1. Values and Symbols Used in SEL Language
1-1 List of Values and Symbols Used
The various functions required in a program are represented by values and symbols.
Function Global range Local range Remarks

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.
