Replacement method
Since the Universal model QCPU retains
the data in the program memory even the
battery voltage drops, the boot file setting
is not necessary.Move the files, which are
booted from the standard ROM to the
program memory, to the program memory.
Replacement method when the
parameter-valid drive and the boot file
setting are set in the High Performance
model QCPU is described in Appendix
5.4.
On the Boot file setting tab of PLC
parameter, select "standard ROM" for the
transfer destination. Note, however, that
the transfer destination of "program" is
fixed to "program memory". (Setting by
DIP switches is not necessary.)
Replacement method
---
Use the frame types below.
• QnA-compatible 2C/3C/4C frame
• QnA-compatible 3E frame
• 4E frame
Replacement method
The Universal model QCPU stores all
storable data (maximum 100) in the built-
in memory.
