Error code list (7000 to 10000)

The following shows the error messages from the error code 7000 to 10000, the contents and 
causes of the errors, and the corrective actions for the errors.

7000

• 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.
■Collateral information

• Common Information:Module No.(CPU No.)

■Diagnostic Timing

• At power ON/At reset

Read the individual information of the error using 
GX Developer, identify the error of the CPU 
module, and remove the error.

• 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.
