(3) Drive Nos. 1, 2, and 4 can be specified. (Drive 3 cannot be specified.)
• Drive 1: Memory card (RAM)
• Drive 2: Memory card (ROM)
• Drive 4: Standard ROM
(4) An extension (.QPG) need not be specified for the file name.
(5) The bit device specified by is turned ON during the END processing of the scan where
this instruction is completed. The bit device is turned OFF at the next END processing.
(6) The PLOADP, PUNLOADP and PSWAPP instructions cannot be executed simultaneously.
If two or more of the above instructions are executed simultaneously, the instruction
executed later will not be executed.
When using the above instructions, provide interlocks manually to avoid simultaneous
execution.
(7) When the Programmable Controller is powered OFF, then ON or the CPU module is reset
after execution of the PSWAPP instruction, the following operation is performed.
(a) When boot setting has been made in the PLC parameter dialog box, the program where
the boot setting has been made is transferred to the program memory.
When the program replaced by the PSWAPP instruction is to be executed, change the
boot setting and program setting of the PLC parameter dialog box for the corresponding
program name.
(b) When boot setting has not been made in the PLC parameter dialog box, "FILE SET
ERROR (error code: 2400)" occurs.
1) When the program replaced by the PSWAPP instruction is to be executed, change
the program setting of the PLC parameter dialog box for the corresponding program
name.
2) To execute the program set in the program setting of the PLC parameter dialog box,
write the corresponding program to the CPU module again.
(8) Do not execute this instruction in an interrupt program.
(Execution of this instruction in an interrupt program can cause a malfunction.)
(9) The PLC file settings of the program on which the PSWAPP instruction has been conducted
are set as follows:
(a) File usage for each program
All the usage of file register, device initial value, comment, and local device of the
program after the execution of the PSWAPP instruction are set as "Use PLC file
setting".
(b) I/O refresh setting
Nothing is set for both input and output for the I/O refresh setting of the program after
the PSWAPP instruction has been executed.
(10) The "PSWAPP instruction" and "write during RUN" processing cannot be executed
simultaneously.
(a) When a write during RUN request is given during processing of the PSWAPP
instruction, write during RUN is delayed.
Write during RUN is started after the processing of the PSWAPP instruction is
completed.
(b) When the PSWAPP instruction is executed during write during RUN, the processing of
the PSWAPP instruction is delayed.
The processing of the PSWAPP instruction is started after completion of write during
RUN.
