Error details and cause
An error has been detected in the I/O module or intelligent
function module during the initial processing.
An error has been detected in the I/O module or intelligent
function module when the instruction was executed.
An error has been detected in the I/O module or intelligent
function module during the END processing.
An error has been detected in the I/O module or intelligent
function module.
• A major error has been notified from the intelligent
function module connected.
• The I/O module or intelligent function module is not
mounted properly or was removed during operation."
An error has been detected in another CPU module during
the initial processing.
An error has been detected in another CPU module.
A major error has been notified from another CPU
module.
• In the multiple CPU system, an error has been detected
in the CPU module where "Stop" is set in the operation
mode setting parameter.
• Any CPU module other than CPU No.1 is mounted in
the inapplicable slot. (An error occurs in the CPU
module mounted in the inapplicable slot.)
In the multiple CPU system, 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.
An error was detected on the system bus.
An error was detected on the system bus.
Corrective action
The possible cause is a hardware failure of the error
module. Please consult your local Mitsubishi
representative.

• Check the connection status of the extension cable.
• Check the detailed information (system configuration
information), and check the module corresponding to
the displayed slot number.
• 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.
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 host CPU module or another CPU module
where the error has been detected. Please consult your
local Mitsubishi representative.
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 host CPU module or another CPU module
where the error has been detected. Please consult your
local Mitsubishi representative.
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 host CPU module or another CPU module
where the error has been detected. Please consult your
local Mitsubishi representative.
• Check the detailed information (system configuration
information), identify the error CPU module, and
eliminate the error cause.
• Remove the CPU module from the inapplicable slot.
Check the mounting status and reset status of the CPU
modules other than CPU No.1.
• Take measures to reduce noise.
• 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 CPU module, base unit,
extension cable, or module (I/O module or intelligent
function module) connected. Please consult your local
Mitsubishi representative.
• Take measures to reduce noise.
• 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 CPU module, base unit,
extension cable, or module (I/O module or intelligent
function module) connected. Please consult your local
Mitsubishi representative.
