[MULTI CPU DOWN]
• 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.
• Any CPU module other than CPU No.1 was
disconnected from the base unit during
operation. Or any CPU module other than CPU
No.1 was reset.
■Collateral information
• Common information: Module No. (CPU No.)
• Individual information:-
■Diagnostic Timing
• Always
• Read the individual information of the error
using the programming tool. Check the error in
the CPU module, and remove the error.
• Remove the CPU module from the main base
unit if it does not support the multiple CPU
system configuration.
• 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.
■Collateral information
• Common information: Module No. (CPU No.)
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
Read the individual information of the error using
the programming tool. Check the error in the CPU
module, and remove the error.

[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.
(Please consult your local Mitsubishi
representative, explaining a detailed description
of the problem.)
• Remove the CPU module from the main base
unit if it does not support the multiple CPU
system configuration. Or, replace the CPU
module incompatible with the multiple CPU
system with the compatible one.
