Chapter 1 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 CPxx (CPEQ, CPNE, CPGT, CPGE, CPLT and CPLE), ECMD 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
