The CPU module configuration in the multiple CPU
system is either of the following.
• There are empty slots between the QCPU and
QCPU/motion controller.
• A module other than the High Performance
model QCPU/Process CPU (including the
motion controller) is mounted on the left-hand
side of the High Performance model QCPU/
Process CPU.

â– Diagnostic Timing
• At power-on/At reset
• Mount modules on the available slots so that
the empty slots will be located on the right-hand
side of the CPU module.
• Remove the modules mounted on the left of the
High Performance model QCPU or Process
CPU. Mount a High Performance model QCPU
or Process CPU on those slots.
Mount the motion CPU on the right-hand side
of the High Performance model QCPU/Process
CPU.

• Individual information:-
â– Diagnostic Timing
At power-on/At reset
• Disconnect the module that cannot be
recognized.
• Reset the CPU module and run it again. If the
same error code is displayed again, the cause
is a hardware failure of the CPU module, I/O
module, intelligent function module, or END
cover. (Please consult your local Mitsubishi
representative, explaining a detailed
description of the problem)
