Error description
An error of the system bus was detected.
An error of the system bus was detected.
An error of the system bus was detected.
An error of the system bus was detected.
An error of the system bus was detected.
There is no module parameter.
The contents in the module parameter are
broken.

The control CPU module does not support
the recording function.
A recording setting file which is not
supported by the firmware version of the
target CPU module was written.
The contents of the recording setting file are
broken.
The module type set in the engineering tool
does not match the CPU module which is
the write destination of the recording setting
file.
Device/label data which exceeds the size of
the buffer area for data sampling in the CPU
parameter is specified in the recording
setting file.
Corrective action
• Please take anti-noise measures.
• Please switch the CPU module to RUN after resetting
it. If the same error is displayed, a hardware error
may have occurred in the CPU module, I/O module,
intelligent function module, base unit, or extension
cable. Please consult your local Mitsubishi
representative.
• Please take anti-noise measures.
• Please switch the CPU module to RUN after resetting
it. If the same error is displayed, a hardware error
may have occurred in the I/O module, intelligent
function module, base unit, or extension cable.
Please consult your local Mitsubishi representative.
• Please take anti-noise measures.
• Please switch the CPU module to RUN after resetting
it. If the same error is displayed, a hardware error
may have occurred in the CPU module or extension
cable. Please consult your local Mitsubishi
representative.
• Please take anti-noise measures.
• Please switch the CPU module to RUN after resetting
it. If the same error is displayed, a hardware error
may have occurred in the I/O module, intelligent
function module, or extension cable. Please consult
your local Mitsubishi representative.
• Please take anti-noise measures.
• Please switch the CPU module to RUN after resetting
it. If the same error is displayed, a hardware error
may have occurred in the CPU module or base unit.
Please consult your local Mitsubishi representative.
• Please check the module position set in the system
parameter of the CPU module (I/O assignment
setting) and the module position of the implemented
module. If they are different, please match the
parameter and implementation status.
• Please write the module parameter again with the
engineering tool. If the same error is displayed again,
please consult your local Mitsubishi representative.
Please write the module parameter again with the
engineering tool. If the same error is displayed again,
please consult your local Mitsubishi representative.
• Please take anti-noise measures.
• Please switch the CPU module to RUN after resetting
it. If the same error is displayed, a hardware error
may have occurred in the recorder module. Please
consult your local Mitsubishi representative.
Please use a CPU module which supports the
recording function.
Please check the version of the CPU module, use a
compatible product, and then write the recording file
again.
• Please take anti-noise measures.
• Please write the recording setting file again. If the
same error is displayed, a hardware error may have
occurred in the data memory of the CPU module.
Please consult your local Mitsubishi representative.
Please read the recording setting file, and match the
write destination CPU module and model type.
Please read the CPU parameter and recording setting
file, and reduce the device/label data to be saving
targets so that the size is within the buffer area for data
sampling in the CPU parameter. Or, please increase
the size of the buffer area for data sampling in the CPU
parameter.
