Applicable products
and software
Products and softwares 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 Appendix
3.2.
Appendix 3.2
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
Appendix 3.2.
Appendix 3.2
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
*1
In a redundant power supply system
using the Q38RB redundant power supply
main base unit and the Q68RB redundant
power supply extension base unit, the
status of the power supply module cannot
be stored in the special relay and special
register (SM1780 to SM1783/SD1780 to
SD1783). The status cannot be displayed
on the system monitor screen.
Check the status of the power supply
module by the LED on the front of the
