A device comment file cannot be stored in an
SRAM card.
Device comment
A device comment file cannot be stored in an
ATA card nor Flash card.
An initial device value file cannot be stored in an
SRAM card.
Initial device value
An initial device value file cannot be stored in an
ATA card nor Flash card.
A local device file cannot be stored in an SRAM

card.
File register
A file register file cannot be stored in a Flash
card. (Sequence programs only can read file
register data in a Flash card.)
A sampling trace file cannot be stored in an
Sampling trace
SRAM card.
CPU module change A memory card cannot be specified as a backup
function with memory card destination or restoration source.
*1 This applies when the High Performance model QCPU is replaced with the High-speed Universal model QCPU.

Item
Module service interval The module service interval time cannot be
time read read.
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
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
