• In the operating mode of a multiple CPU system,
a CPU error occurred at the CPU where "All
station stop by stop error of CPU " was selected.
• In a multiple CPU system, a CPU module
incompatible with the multiple CPU system was
mounted.
• CPU modules other than CPU No.1 were
removed from the base unit in operation, or
reset.
■Collateral information
• Common Information:Module No.(CPU No.)
• Individual Information:–

• Always
• Read the individual information of the error using
GX Developer, identify the error of the CPU
module, and remove the error.
• Remove the CPU module incompatible with the
multiple CPU system from the main base unit.
• Check the mounting status of CPU modules
other than CPU No.1 and whether the CPU
modules were reset.

[MULTI CPU DOWN]
In a multiple CPU system, CPU other than CPU
No.1 cannot be started up due to stop error of the
CPU No.1 at power-on, which occurs to CPU No.2
to No.4.

[MULTI CPU DOWN]
• There is no response from the target CPU
module in a multiple CPU system during initial
communication.
• In a multiple CPU system, a CPU module
incompatible with the multiple CPU system was
mounted.
■Collateral information
• Common Information:Module No.(CPU No.)
• Individual Information:–
■Diagnostic Timing
• At power ON/At reset
• Reset the CPU module and RUN it again. If the
same error is displayed again, this suggests the
hardware fault of any of the CPU modules.
(Contact your local Mitsubishi representative.)
• Remove the CPU module incompatible with the
multiple CPU system from the main base unit.
Or, replace the CPU module incompatible with
the multiple CPU system with the compatible
one.
