*1 This error occurs only once when an abnormality is detected. Before clearing the error, eliminate the cause and check that a data link is
established.
*2 For these types of errors, more than one error may not occur at the same time. If errors occur, eliminate the cause of one error after
another until a data link is established.
Description and cause
The function setting switch 10 has
been changed with the module
power supply on.
The upper limit for the number of
times an error is saved in the error
history is reached.
The upper limit for the number of
times the IP address is changed
is reached.
The module power supply voltage
is dropped.
The IP address cannot be saved
because an error in access to the
non-volatile memory was
detected.
The error cannot be saved
because an error in access to the
non-volatile memory was
detected.
Invalid network settings are
received.
Network settings that cannot be
handled by the I/O module are
received.
An IP address duplication is
detected.
Values the I/O module cannot use
were set for the IP address and
subnet mask settings.
The network synchronous
communication setting of the I/O
module is set to synchronous.
RX/RY with a number of points
that cannot be handled by the I/O
module are set.
RWr/RWw with a number of
points that cannot be handled by
the I/O module are set.
Action
Return the function setting switch 10 to the setting when the
module power supply was on.
No more errors can be saved in the error history. Check the
error by the latest error code.
An IP address change made when and after this error
occurred is not saved into the non-volatile memory.
• Check the state of the module power supply.
• Check if the power supply voltage satisfies the
specifications for the I/O module.
• The IP address is not saved into the non-volatile memory.
• Take measures against noise with a shielded cable for
connection.
• If this error occurs again, the possible cause is a module
failure. Please consult your local Mitsubishi representative.
• An error that occurred at the time of or before this error
may not be saved into the non-volatile memory.
• Take measures against noise with a shielded cable for
connection.
• If this error occurs again, the possible cause is a module
failure. Please consult your local Mitsubishi representative.
Power off and on the module power supply.
If this error occurs again, the possible cause is a module
failure.
Please consult your local Mitsubishi representative.
Check that the model name of the slave station set in the
network configuration settings matches the model name of
the actual device.
If this error occurs even when the model names match, the
possible cause is a module failure. Please consult your local
Mitsubishi representative.
Change the IP address so that no IP address duplication
occurs in the access range of CC-Link IE TSN. After change,
power off and on the module power supply.
• Without using the set IP address and subnet mask, the
module is operated based on the previous IP address and
subnet mask.
• The set IP address and subnet mask will not be saved in
non-volatile memory.
• Check the IP address and subnet mask again, and change
the settings to values the I/O module can use. After
change, power off and on the module power supply.
Set the network synchronous communication setting of the I/
O module to asynchronous.
Set 32 or less for the number of points for RX and RY in the
network configuration setting.
Set 144 or less for the number of points for RWr and RWw in
the network configuration setting.
