Action
• Check the parameter set in "EtherNet/IP Configuration"
and write the parameter to the module 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.
• Check whether the operating status of the external device
is normal.
• Check for errors in the line status.
• The line may be busy, so retry the operation after a while.
• Check that a value other than 0 (start request) is set for
'EtherNet/IP communication start request' (Un\G7340096).
• Check that 'Class1 cyclic pause specification'
(Un\G7735808 to Un\G7735823) is set to 0 (no cyclic
pause request).
• Refer to the manuals for the external device and the
EtherNet/IP specification (THE CIP NETWORKS
LIBRARY Volume 1 Common Industrial Protocol (CIP
to check the conditions under which a notification is made
for this error and the action to take.
• Close the connection of the external device and retry.
• Retry after the connection of the external device has been
timed out.
Refer to the manuals for the external device and the
EtherNet/IP specification (THE CIP NETWORKS LIBRARY
Volume 1 Common Industrial Protocol (CIP
conditions under which a notification is made for this error
and the action to take.
Refer to the manuals for the external device and the
EtherNet/IP specification (THE CIP NETWORKS LIBRARY
Volume 1 Common Industrial Protocol (CIP
conditions under which a notification is made for this error
and the action to take.
Check the following items, and then restart the EtherNet/IP
communications.
• Is the operating status of the external device normal?
• Is the line status normal?
