2) Timing for execution type change
The program execution type is changed in the END processing.
Hence, it is not changed midway through program execution.
When different types are set to the same program in the same scan, it is
changed to the execution type executed by the latest instruction.
END processing
Execution
"GHI"
program name
* : The "GHI" and "DEF" programs are executed in the order set in the program setting of the PLC
parameter dialog box.
Diagram 3.41 Timing for execution type change
(a) Unavailable devices
Unavailable devices depend on the program type (subroutine program, interrupt
program) or the execution type changed by an instruction.
(b) Execution of subroutine program using local device
Refer to Section 9.13.1 for execution of the subroutine program using a local
device.
(a) Program
When setting the created program as a stand-by type program in advance, set the
execution type to "Wait" in the program setting of the PLC parameter dialog box.

END processing
"DEF" "GHI"
"DEF" is changed to scan
execution type, and "ABC" is
changed to stand-by type
program.
