Part 2 Programs
Chapter 2 List of SEL Language Command Codes
1. By Function
Variables can be specified indirectly in the operand 1, operand 2 and output fields.
Symbols can be input in the condition, operand 1, operand 2 and output fields.
The input items in ( ) under operand 1 and operand 2 are optional.
Once an “actuator control declaration” command is executed in a program, the command will remain valid
as long as the program is running. To change the values (in operand 1, operand 2, etc.) already set by the
“actuator control declaration” command, the necessary parts of the program must be set again. In other
words, the values set by the last executed command will prevail.
The output field will be turned OFF when the command is executed. Once the execution is completed, the
output field may be turned ON depending on the operation type condition in the output field. (The output field
will remain OFF if the condition is not satisfied.)
Note: The output field of a comparison command CP
 (CPEQ, CPNE, CPGT, CPGE, CPLT and CPLE) will
not be turned OFF when the command is executed.
Operation type in the output field
CC: Command was executed successfully,
ZR: Operation result is zero, PE: Operation is complete,
CP: Command part has passed, TU: Time up
EQ: Operand 1 = Operand 2, NE: Operand 1
 Operand 2,
GT: Operand 1 > Operand 2, GE: Operand 1  Operand 2,
LT: Operand 1 < Operand 2, LE: Operand 1  Operand 2
