Appendix 5.1.2 Replacing High Performance model QCPU with
Universal model QCPU
(1) System configuration
Item Precautions Replacement method Reference
Use of AnS/A series
module
The Universal model QCPU whose serial
number (first 5 digits) is "13102" or later must
be used.
Use Q series modules when using the Universal
model QCPU whose serial number (first 5
digits) is "13101" or earlier.
---
GOT GOT900 series cannot be connected. Use GOT1000 or GOT2000 series. ---
Programming tool
connection
Applicable USB cables are different.
• High Performance model QCPU
... A-B type
• Universal model QCPU
... A-miniB type
Use USB cables of A-miniB type. Or, use USB
conversion adapters of B-miniB type.
---
Applicable products and
software
Products and software compatible with the
Universal model QCPU must be used.
Products need to be replaced for the
compatibility with the Universal model QCPU
and software need to be upgraded for the
communication with the Universal model QCPU
are described in Page 513, Appendix 5.2.
Page 513, Appendix 5.2
Multiple CPU system
To configure a multiple CPU system, CPU
modules compatible with the Universal model
QCPU must be used.
CPU modules compatible with the Universal
model QCPU are described in Page 513,
Appendix 5.2.
Page 513, Appendix 5.2
In a multiple CPU system using the Motion
CPU, an existing auto refresh area and user
setting area cannot be used for data
communication with the Motion CPU.
For data communication with the Motion CPU,
use an auto refresh area and user setting area
in the multiple CPU high-speed transmission
area.

Redundant power supply
system
To check the status of the power supply
module in a redundant power supply system by
using SM1780 to SM1783/SD1780 to SD1783
or with the system monitor screen, the
Universal model QCPU whose serial number
(first 5 digits) is "10042" or later must be used.
Check the status of the power supply module
with the LED on the front of the module when
using the Universal model QCPU whose serial
number (first 5 digits) is "10041" or earlier. (In a
redundant power supply system, the status of
the power supply module cannot be stored in
SM1780 to SM1783/SD1780 to SD1783. The
status cannot be displayed on the system
monitor screen either.)

Interlink transmission timing differs.
Add a handshake program to the send side and
receive side so that the module does not
receive data while sending data.
