14 Multi CPU Errors (A) [C80]
A01 Remote A password setting error
Details
In the multiple CPU system, the module controlled by another CPU module is specified by the start I/O
number of the remote password setting.
Remedy
Check and correct the remote password setting.
A01

Module verification error

Details
The module information at power-on differs from the information of modules actually mounted.
The I/O module or intelligent function module is not mounted properly or was removed during operation.
Remedy
Check the detailed information (system configuration information) of the error by executing module diag-
nostics using the engineering tool, and check the module corresponding to the displayed number.
A01 Module verification error
Details
A CPU module, I/O module, or intelligent function module was mounted on the base unit during operation.
Remedy
Check the detailed information (system configuration information) of the error by executing module diag-
nostics using the engineering tool, and check the module corresponding to the displayed number.
Do not mount a CPU module, I/O module, nor intelligent function module during operation.
A01

Fuse blown error

Details
The output module with a blown fuse has been detected.
Remedy
Check the FUSE LED of each output module, and replace the one with the FUSE LED on.
Check the detailed information (system configuration information) of the error by executing module diag-
nostics using the engineering tool, and replace the module corresponding to the displayed number.
A01

Module major error

Details
In the multiple CPU system, the control CPU setting in the system parameters is different from that of other
numbered CPU modules.
An error has been detected in the I/O module or intelligent function module during the initial processing.
Remedy
Correct the system parameter settings for the CPU No.2 and later. The settings need to be the same be-
tween all the CPU modules.
Reset the CPU module, and run it again. If the same error code is displayed again, the possible cause is
a hardware failure of the error module. Please consult your local Mitsubishi representative.
A01 Module major error
Details
An error has been detected in the I/O module or intelligent function module during the END processing.
Remedy
The possible cause is a hardware failure of the error module. Please consult your local Mitsubishi repre-
sentative.
A01 Module major error
Details
An error has been detected in the I/O module or intelligent function module.
Remedy
The possible cause is a hardware failure of the error module. Please consult your local Mitsubishi repre-
sentative.
