(b) When the parameter-valid drive is set to the memory card (RAM) or memory card
(ROM) in the High Performance model QCPU
*1 Since the Universal model QCPU holds the data in the program memory even when the battery voltage drops, the boot
file setting is not necessary.
*2 The Universal model QCPU searches for parameters in order of in the program memory, in the memory card or SD
memory card, and in the standard ROM. Then, the module uses the parameters found first. If parameters exist in the
program memory or the card, the Universal model QCPU does not use the parameters in the standard ROM.
Setting in High Performance model QCPU
Setting in Universal model QCPU
Setting in the Boot file tab
of the PLC parameter dialog box
No boot file setting
Change the setting so that the Universal model QCPU can refer to the
parameters in the memory card or SD memory card.
• Changes in parameter settings are not required.
• Delete parameters that exist in the program memory.
*2
Settings in the Boot file tab
(No boot file setting for parameters)
Change the setting so that the Universal model QCPU can refer to the
parameters in the memory card or SD memory card.
• Changes in parameter settings are not required.
• Delete parameters that exist in the program memory.
*2
Settings in the Boot file tab
No changes are required.
Settings in the Boot file tab
(No boot file setting for parameters)
Change the setting so that programs are stored in the program memory in the
first place, instead of booting from the standard ROM.
• Move the programs targeted for booting from the standard ROM into the
program memory.
*1
• Delete all settings for program in the Boot file tab of the PLC parameter
dialog box.
• Delete parameters that exist in the program memory.
*2
Settings in the Boot file tab
Change the setting so that programs are stored in the program memory in the
first place, instead of booting from the standard ROM.
• Move the programs targeted for booting from the standard ROM into the
program memory.
*1
• Delete all settings for program in the Boot file tab of the PLC parameter
dialog box.
Settings in the Boot file tab
Delete all settings for data other than programs and parameters in the boot file
setting.
Since these data can be used even not stored in the program memory, it is not
necessary to transfer them to the program memory. Or, change the setting so
that they are stored in the program memory in the first place.
• Delete all settings for data other than programs and parameters in the Boot
file tab of the PLC parameter dialog box.
• Move the data other than programs and parameters into the program
memory as needed.
Settings in the Boot file tab
(Data other than program and parameter indicate initial
device value, device comment, and label program.)
