(5) Changing the program file during RUN

(a) Changing method
During RUN of the High Performance model QCPU, Process CPU or Universal
model QCPU, 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, Process CPU or Universal model QCPU, the program setting in the
PLC parameter dialog box is not changed.
Hence, when the High Performance model QCPU, Process CPU or Universal
model QCPU 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, Process CPU or Universal model QCPU (addition/
change/deletion of program name).
Otherwise, an error will occur when the CPU is switched from STOP to RUN
status.
