• Bit devices are used as word data by
specifying digits using K1, K2, K3, K5, K6, or
K7, or by specifying a device number of other
than multiples of 16.
*1 Even the local device file usability setting is not available for the Q02UCPU, Q03UDCPU, Q04UDHCPU, and
Q06UDHCPU if the serial number (first five digits) is "10011" or earlier.

Replacement method
Use the RFS instruction if I/O refresh setting for
each program is required.
Replace the corresponding special relay and
special register as described in Page 555,
Appendix 5.5.
By using a programming tool, A series-
compatible special relay and special register
can be replaced with the Universal model
QCPU-compatible special relay and special
register.
Note, however, that the ones which are not
compatible with the Universal model QCPU are
replaced with SM1255 and SD1255. Modify
programs as needed.
Modify programs as needed, checking the
processing timing.
If index modifications mentioned on the left are
frequently used in the program, the program
size may exceed the storage capacity of the
replaced CPU module. After the program
controller type is changed, check the program
size using the confirm memory size function. If
the program size exceeds the storage capacity,
take the following actions or change the CPU
module to that with larger program memory.
• Move parameters and device comments to
the standard ROM.
• Reduce the reserved area for online change.
• Use the file register, extended data register,
and extended link register within 64K words
because the number of steps decreases by
one when used in that way.
Replacement method
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.
Move files with the boot setting (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 Page
548, Appendix 5.4.6.
Specify an SD memory card as a transfer
source.
In the Boot file tab of the PLC parameter dialog
box, 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.)
