1. PRECAUTIONS FOR REPLACEMENT
(1) System configuration
Item Precaution Replacement method Reference
RS-232 port There is no RS-232 port.*1 Use a USB or Ethernet port.
To communicate with an RS-232
interface, use the QJ71C24N(-R2) in
the system.
-
Applicable products and
software
A programming tool that was
available for the QnUD(E)(H)CPU
can no longer be used or needs to
be upgraded. (The use of GX
Developer is not supported in the
system after replacement.)
Some GOTs and intelligent
function modules that were
available for the QnUD(E)(H)CPU
can no longer be used or need to
be upgraded.
Upgrade the version of GX Works2
to the one compatible with the
QnUDVCPU.
Replace the GOT and intelligent
function modules to those
compatible with the QnUDVCPU.
Chapter 2
Multiple CPU system Scan time is shortened in the
High-speed Universal model QCPU
because operations are performed
at higher speed. When used in a
multiple CPU system, the
High-speed Universal model QCPU
accesses to the control modules
frequently. As a result, the
processing time in other CPU
modules may increase.
Check the processing timing of other
CPU modules and adjust the access
frequency of the High-speed
Universal model QCPU using timers
or the constant scan function.
QCPU User's Manual
(Multiple CPU System)
Current consumption The current consumption increases. Select a power supply module
according to the total current
consumption in the system.

Inspection)

(2) Program
Item Precaution Replacement method Reference
Number of steps The number of basic steps differs in
some instructions.
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.
MELSEC-Q/L Programming
Manual (Common
Instruction)
The number of steps increases by
one when:
Index modification is performed.
A leading or trailing edge
instruction is used.
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.
(3) Parameter size
Item Precaution Replacement method Reference
Parameter size The parameter size increases
because the built-in Ethernet port
setting parameters are added.*1
Delete unnecessary files and free
some space.
Move the parameter file to another
memory area.

If the size of the local device file
exceeds the standard RAM
capacity, consider the use of an
extended SRAM cassette.

User's Manual (Function
Explanation, Program
Fundamentals)
File register A file register file cannot be stored in
an SRAM card.
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.
Section 4.7.1 in the

(Function Explanation,
Program Fundamentals)
A file register file cannot be stored in
a Flash card. (Sequence programs
only can read file register data in a

(5) Built-in Ethernet port communications*1
Item Precaution Replacement method Reference
File transfer function (FTP
server)
The security function has been
enhanced from the password
registration function to the file
password 32 function. For this
reason, the keyword-set
subcommand, that
sets/displays/clears the file access
password, is no longer supported.
Use the FTP commands, passwd-rd
and passwd-wr, that
set/display/clear the read/write
passwords of the file password 32
function.

(6) Functions
Item Precaution Replacement method Reference
Security function The security function, that limits
accesses to the files in the CPU
module, has been enhanced from
the password registration function to
the file password 32 function.
Use the file password 32 function
instead of the password registration
function.
Section 3.19 in the
QnUCPU User's Manual
(Function Explanation,
Program Fundamentals)
Latch data backup to
standard ROM
If an extended SRAM cassette is
used and the memory capacity of
the standard RAM (drive 3) is larger
than that of the standard ROM, data
cannot be backed up using this
function.
Deselect the “Backup all files in the
internal of standard RAM” checkbox
in the PLC System tab of the PLC
parameter dialog box.

as same as that of the
QnUD(E)(H)CPU.
The switch setting parameters are
ignored and the following operations
are performed.
Data held by the battery are not
cleared nor deleted.
The bits, b0 and b1, of SD119
(Battery life-prolonging factor) are
fixed to 0.
