5.2.8 Execution of standard ROM/memory card programs (boot run)
(a) Changing method
During RUN of the High Performance model QCPU or Process CPU, files can be
added, changed and deleted from the standard ROM or memory card to the
program memory with the following instructions in a sequence program.
• PLOADP instruction (program transfer from memory card to program
memory)
• PUNLOADP instruction (program deletion from program memory)
• PSWAPP instruction (program deletion from program memory and program
transfer from memory card to program memory)
Refer to the following manual for details of the PLOADP instruction, PUNLOADP
instruction and PSWAPP instruction.

(b) Program setting made when program file is changed
Even if a program file has been changed during RUN of the High Performance
model QCPU or Process CPU, the program setting in the PLC parameter dialog
box is not changed.
Hence, when the High Performance model QCPU or Process CPU is set to a
STOP status, correct the program setting of the PLC parameter dialog box to the
current settings made during RUN of the High Performance model QCPU or
Process CPU (addition/change/deletion of program name).
Otherwise, an error will occur when the CPU is switched from STOP to RUN
status.
(a) Parameter storage location
When executing boot run, store the parameters (PLC parameters) specified in the
boot file setting to the standard ROM or memory card.
If they are stored into the program memory and the parameter-valid drive DIP
switches are set to the program memory, the boot file setting of the PLC
parameter dialog box is ignored and a boot is not executed when the PLC is
powered ON or the High Performance model QCPU, Process CPU or Redundant
CPU is reset.
(b) Online program change during boot run
1) Memory card (RAM)
When online program change (
the program memory, the change can be updated to the program of the boot
source memory card (RAM).
The Basic model QCPU and Redundant CPU cannot change the program file during RUN using
the PLOADP instruction, PUNLOADP instruction and PSWAPP instruction.
