CHAPTER 11 TROUBLESHOOTING
Description
Action
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.
Set the value of Range setting (address: 0103H)
within the allowable range.
• 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.
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.
• 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.
• 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.
Reset network parameter correctly.
Correct the setting data of the REMFR/REMTO
instruction to access the remote buffer memory.
