3E01H Network type of the own station is unexpected setting. Rewrite the module parameter using the engineering
tool. If the error occurs again even after taking the
above, the possible cause is a hardware failure of the
error module. Please consult your local Mitsubishi
representative.
4000H to
4FFFH
Errors detected by the CPU module ( MELSEC iQ-R CPU Module User's Manual (Application))
D000H An error was detected in the network module. Please consult your local Mitsubishi representative.
D038H The target station specified in the IP communication
test is not connected.
If the own station, target station, or relay station is
disconnected from the network, identify the cause of
the disconnection and take action.
D039H There is a station that does not support the IP packet
transfer function on the communication path of the IP
communication test.
Check the station on the communication path of the IP
communication test, and check whether the module in
the station supports the IP packet transfer function.
D041H The number of communication stations is incorrect. • Check the network status using the CC-Link IE Field
Network diagnostics of the engineering tool, and
take action.
• If the number of slave stations (including a
submaster station) per network is more than 120,
reduce it to 120 or less.
D080H to
D083H
An error was detected in the network module. Please consult your local Mitsubishi representative.
D0A0H Transmission response wait timeout has occurred in
transient transmission.
• Check the network status using the CC-Link IE Field
Network diagnostics of the engineering tool, and
take action.
• When the own station, target station, or relay station
detected an error, identify the cause of the error and
take action.
• Lower the transient transmission usage frequency,
and then perform again.
• When "Communication Mode" in "Application
Settings" of the master station (submaster station) is
set to "High-Speed", change it to "Normal" and retry
the operation.
• Check if the switching hub and the cables at the
request source are connected properly.
D0A1H Transmission completion wait timeout has occurred in
transient transmission.
• Check the network status using the CC-Link IE Field
Network diagnostics of the engineering tool, and
take action.
• When the own station, target station, or relay station
detected an error, identify the cause of the error and
take action.
• Lower the transient transmission usage frequency,
and then perform again.
• When "Communication Mode" in "Application
Settings" of the master station (submaster station) is
set to "High-Speed", change it to "Normal" and retry
the operation.
• Check if the switching hub and the cables at the
request source are connected properly.
D0A2H Transmission processing wait timeout has occurred in
transient transmission.
• Lower the transient transmission usage frequency,
and then perform again.
• Check if the switching hub and the cables at the
request source are connected properly.
D0A3H Send processing of the transient transmission has
failed.
• Check the network status using the CC-Link IE Field
Network diagnostics of the engineering tool, and
take action.
• When the own station, target station, or relay station
detected an error, identify the cause of the error and
take action.
• Correct the target station number of transient data,
and retry the operation.
• When the access destination is a module with a
different network number, check if "Routing Setting"
of "CPU Parameter" is correctly set.
