Part 3 Controller Data Structure
Chapter 2 X-SEL Language Data (IX-Series Controller)
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
Input port 000 ~ 299 (300)
Varies depending on
the function.
Output port 300 ~ 599 (300)
Varies depending on
the function.
Flag 600 ~ 899 (300) 900 ~ 999 (100)
Variable (integer)
200 ~ 299 (100)
1200 ~ 1299 (100)
1 ~ 99 (99)
1001 ~ 1099 (99)
99 is used for IN, INB,
OUT, OUTB, etc.
Variable (real)
300 ~ 399 (100)
1300 ~ 1399 (100)
100 ~ 199 (100)
1100 ~ 1199 (99)
199 is used for PPUT,
PGET, PARG, etc.
String 300 ~ 999 (700) 1 ~ 299 (299)
Tag number 1 ~ 99 (99)
Subroutine number 1 ~ 99 (99)
Load coordinate system 0 ~ 31 (32)
Tool coordinate system 0 ~ 127 (128)
Simple interference check
zone number
1 ~ 10 (10)
Pallet number 1 ~ 10 (10)
Axis number 1 ~ 4 (4)
Varies depending on
the function.
Axis pattern 0 ~ 1111
Position number 1 ~ 3000 (3000)
Program number 1 ~ 64 (64)
Step number 1 ~ 6000 (6000)
Task level NORMAL/HIGH (2)
SIO channel number
1 ~ 1 (1) (Also used
for TP/PC)
Wait timer 1
1-shot pulse timer
16 (Number of timers
that can be operated
simultaneously)
Ladder timer Local flag (100)
Virtual input port (SEL system
→ SEL user program)
7000 ~ 7299 (300)
Virtual output port (SEL user
program
→ 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
• 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.
