CPU module change A memory card cannot be specified as a backup
function with memory card destination or restoration source.

To access CPU modules by using A-compatible
1C frame and A-compatible 1E frame, the
Q10UDHCPU, Q20UDHCPU, Built-in Ethernet
port QCPU, or the modules (Q02UCPU,
Q03UDCPU, Q04UDHCPU, Q06UDHCPU,
Q13UDHCPU, and Q26UDHCPU) whose serial
numbers (first 5 digits) are "10102" or later must
be used.
MC protocol
The following commands cannot specify
monitoring conditions.
• Randomly reading data in units of word
(Command: 0403)
• Device memory monitoring (Command: 0801)
The applicable frame types are as follows:
• QnA-compatible 3C/4C frame
• QnA-compatible 3E frame
• 4E frame

Replacement method
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.)
Store the file in the standard RAM.
Store the file in an SD memory card.
Store the file in the standard RAM or standard
ROM.
Store the file in an SD memory card.
• Store the file in the standard RAM.
• If the size of the local device file exceeds the
standard RAM capacity, consider the use of
an extended SRAM cassette.
• Store the file in the standard RAM.
• If the size of the file register file exceeds the
standard RAM capacity, consider the use of
an extended SRAM cassette.
Use the initial device value file in an SD memory
card or the FREAD/FWRITE instructions.
• Store the file in the standard RAM.
• If the size of the sampling trace file exceeds
the standard RAM capacity, consider the use
of an extended SRAM cassette.
Specify an SD memory card as a backup
destination or restoration source.
Replacement method

Use the frame types below when using the
modules (Q02UCPU, Q03UDCPU,
Q04UDHCPU, Q06UDHCPU, Q13UDHCPU,
and Q26UDHCPU) whose serial numbers (first
5 digits) are "10101" or earlier.
• QnA-compatible 2C/3C/4C frame
• QnA-compatible 3E frame
• 4E frame
