Error
Code Error Contents and Cause
(SD0)
[MULTI CPU DOWN]
• In the operating mode of a multiple CPU system,
a CPU error occurred at the CPU where "All sta-
tion stop by stop error of CPU " was selected.
• In a multiple CPU system, a CPU module incom-
patible 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:–
7000
■Diagnostic Timing
• Always
[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
[MULTI CPU DOWN]
• There is no response from the target CPU mod-
ule in a multiple CPU system during initial com-
munication.
• In a multiple CPU system, a CPU module incom-
patible with the multiple CPU system was
mounted.
■Collateral information
• Common Information:Module No.(CPU No.)
• Individual Information:–
■Diagnostic Timing
7002
• At power ON/At reset
[MULTI CPU DOWN]
• There is no response from the target CPU mod-
ule in a multiple CPU system during initial com-
munication.
■Collateral information
• Common Information:Module No.(CPU No.)
• Individual Information:–
■Diagnostic Timing
• At power ON/At reset
[MULTI CPU DOWN]
There is no response from the target CPU module
in a multiple CPU system at initial communication
stage.

Corrective Action
• Read the individual information of the error using
GX Developer, identify the error of the CPU mod-
ule, 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 mod-
ules were reset.
Read the individual information of the error using
GX Developer, identify the error of the CPU mod-
ule, and remove the error.
• 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. (Con-
tact 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.
• 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. (Con-
tact your local Mitsubishi representative.)
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.)
