[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.
• At power-on/reset, momentary power failure has
occurred.
■Collateral information
• Common information: Module No. (CPU No.)
• Individual information: -
■Diagnostic timing
• Always
• Read the common information of the error
using the programming tool. Check the
error in the CPU module, and eliminate the
error cause.
• 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.
• Check the power supply.
• The cause is a hardware failure of the
power supply module. Please consult your
local Mitsubishi representative.

[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 common information of the error
using the programming tool. Check the error
in the CPU module, and eliminate the error
cause.

[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 code is displayed again, the
cause is a hardware failure of any of the
CPU modules. Please consult your local
Mitsubishi representative.
• Remove the CPU module from the main
base unit if it does not support a multiple
CPU system configuration. Alternatively,
replace the CPU module that does not
support a multiple system configuration
with the one that does.

There is no response from the target CPU module
in a multiple CPU system during initial
communication.
■Collateral information
• Common information: Module No. (CPU No.)
• Individual information: -
■Diagnostic timing
• At power-on/At reset
Reset t
he CPU module and run it again. If the
same error code is displayed again, the
cause is a hardware failure of any of the CPU
modules. Please consult your local Mitsubishi
representative.

There is no response from the target CPU module
in a multiple CPU system at initial communication
stage.
■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 code is displayed again, the
cause is a hardware failure of any of the CPU
modules. Please consult your local Mitsubishi
representative.
