Appendix 5.4.6; Parameter-Valid Drive And Boot File Setting - Mitsubishi Electric MELSEC-Q00U(J)CPU User Manual

Appendix 5.4.6

(1) Differences between High Performance model QCPU and Universal model
QCPU
(a) High Performance model QCPU
The parameter-valid drive is specified by the switches on the front panel of the High Performance model
QCPU.
(b) Universal model QCPU
The Universal model QCPU automatically determines the parameter-valid drive, depending on the existence of
parameters in the drive (program memory, memory card, SD memory card, or standard ROM).
Therefore, when replacing the High Performance model QCPU with the Universal model QCPU, changing the
boot file setting for parameter and/or moving files to another drive may be required.
When replacing the High Performance model QCPU with the Universal model QCPU, change the setting as
described below.
(2) Replacing High Performance model QCPU with Universal model QCPU
(a) When the parameter-valid drive is set to the standard ROM in the High Performance

Parameter-valid drive and boot file setting

Change the setting so that the Universal model QCPU can refer to the
parameters in the standard ROM.
• Changes in parameter settings are not required.
• Delete parameters that exist in the program memory, memory card, and/or
SD memory card.
Change the setting so that programs are stored in the program memory in the
first place, instead of booting from the standard ROM.
• Delete all settings for parameter in the Boot file tab of the PLC parameter

• Delete parameters that exist in the program memory, memory card, and/or
SD memory card.
• Move the programs with boot setting into the program memory from the
standard ROM.
Change the setting so that programs and parameters are stored in the
program memory in the first place, instead of booting from the standard ROM.
