11.2 Error Code List
11.2.1 Main A/D converter module
(1) Error code list (0000H to 0FFFH, 1F00H to 1F40H, D529H, D52BH)
The errors are classified into the following three types:
If any of these errors occur, check that the D LINK LED lights up, and take the corrective actions corresponding to
the error code with the list below.
Classification Description
Major error This error is a sign that recovery is impossible, with the RUN LED turning off.
Moderate error This error is a sign that the module cannot continue to operate, with the ERR. LED turning on.
Minor error This error is a sign that the module can continue to operate, with the ERR. LED flashing.
Error code
(hexadecimal)
Classification Error name Description and cause Action
0010H Major error Hardware failure Module hardware error
Turn off and on the module power supply.
If this error persists, the failure of the module is a
possible cause. Please consult your local
Mitsubishi representative.
010H Moderate error
Range setting out-
of-range
The value set in Range setting (address:
0103H) is out of the range.
indicates the number of the channel that has
been incorrectly set.
Set the value of Range setting (address: 0103H)
within the allowable range.
0110H
*1
Moderate error
Non-volatile
memory data error
(module working
information)
The non-volatile memory data are abnormal.
• Change Module operation information
initialization command (address: 1004H) as
follows: Not commanded (0) → Commanded (1)
→ Not commanded (0). Then, adjust the
module operation information of the non-volatile
memory to the default value.
• Take anti-noise measures including the use of
shielded cables for connection.
• If this error persists, the failure of the module is
a possible cause. Please consult your local
Mitsubishi representative.
0120H
*1
Moderate error
User range data
damaged (The
channel cannot be
identified.)
The value set in the offset/gain setting is
invalid.
The channel where the error has occurred
cannot be identified.
Start over the offset/gain setting of all channels
where the user range setting is used.
If an error occurs, please consult your local
Mitsubishi representative.
0130H Moderate error
Non-volatile
memory data error
(parameter)
The parameter data stored in the non-volatile
memory are abnormal.
• Set no request (0), request (1), and no request
(0) in Parameter information clear request
(address: 1002H) and set the parameters of the
non-volatile memory to default.
• Set the parameters again.
• Take measures against noise with a shielded
cable for connection.
• If this error persists, the failure of the module is
a possible cause. Please consult your local
Mitsubishi representative.
0140H Minor error
Non-volatile
memory data error
(error history)
The error history data stored in the non-volatile
memory are abnormal.
• The module will be automatically recovered
immediately after the error occurs. Note that the
error history of the errors that have occurred will
be lost.
• Take measures against noise with a shielded
cable for connection.
• If this error persists, the failure of the module is
a possible cause. Please consult your local
Mitsubishi representative.
0150H Minor error
Incorrect network
parameter access
error
Access to A/D converter module when network
parameter was in the incorrect status.
Reset network parameter correctly.
0160H Minor error
Remote buffer
memory access
error
A buffer memory area other than the remote
buffer memory areas has been accessed using
the REMFR/REMTO instruction.
Correct the setting data of the REMFR/REMTO
instruction to access the remote buffer memory.
