Processing details
• These instructions change the execution type of the program with the file name stored in the device specified by (file
name). If the program is a scan execution type, the output is turned off (non-execution processing) in the next scan. The
program will be a standby type in the following scan and later. When the program is a fixed scan execution type or event
execution type, it becomes a scan execution type in the next scan and turns off (non-execution processing) the output. The
program will be a standby type in the following scan and later.
• Only programs stored in program memory can be changed to a standby type.
• The POFF(P) instruction takes precedence even when the execution type is specified in parameter.
• Extension ".PRG" does not need to be specified as a part of file name. (Only .PRG files can be processed by these
instructions.)
Operation error
Error code Description
(SD0)
2840H The program with the file name specified by (file name) does not exist.
2841H The program with the file name specified by (file name) is not registered in parameter.
2842H The type of the program with the file name specified by (file name) is not supported.
Non-execution processing is the same as the processing performed by each coil instruction with the condition
contact set to off.
B
A, B: Program name
(1)Specify the program A, and execute the POFF instruction.
(2)The program A is not executed.
(3)The program A changes to a standby type program.
The operation results of each coil instruction after the non-execution processing will be as follows, regardless
of the on/off state of the condition contact.
• OUT instruction: The output is forcibly turned off.
• SET, RST, SFT, basic, and application instructions: Status is held.
• PLS and PLS conversion instructions (P): Same processing as when the condition contact is set to off
• OUT T instruction: The current value of the low-speed/high-speed timer is 0.
• OUT ST and OUT C instructions: Current value is held.
For how to change the program execution type, refer to the following.
