was retried.
D905H A communication monitoring timeout has occurred
in communication test.
D906H Transmission completion wait timeout has occurred
in communication test.
D909H The header information of transient transmission is
incorrect.
D90AH During execution of the communication test, the test
was retried.
D90BH The number of stations that communicate in the
network is out of the specification range.
D90CH The target station specified for the communication
test is incorrect.
D912H Transient transmission sending has failed.
D913H to D917H An error was detected in the network module.
D919H No response from the target station of the
communication test.

DA01H An error was detected in the network module.
DA10H to DA17H An error was detected in the network module.
DA19H An error was detected in the network module.
Action
• Correct the target network number at the transient request source, and retry the
operation.
• Correct the communication path from the transient request source to the
destination, and retry the operation.
• When the dynamic routing is not used, or the module of the series other than
MELSEC iQ-R is included, retry the operation after correcting the routing setting.
• Change the system configuration so that the number of relay stations may be
seven or less.
Please consult your local Mitsubishi representative.
Correct the request data at the transient request source, and retry the operation.
Please consult your local Mitsubishi representative.
After completion of the communication test, retry the operation.
• Check the network status using the CC-Link IE Field Network diagnostics of the
engineering tool, and take action. Then, retry the operation.
• Check if "Routing Setting" of "CPU Parameter" is correctly set, and take action.
• Check the network status using the CC-Link IE Field Network diagnostics of the
engineering tool, and take action. Then, retry the operation.
• 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 "Routing Setting" are correctly set.
Correct the header information at the transient request source, and retry the
operation.
Check the network status using the CC-Link IE Field Network diagnostics of the
engineering tool, and take action. Then, retry the operation.
• Check the network status using the CC-Link IE Field Network diagnostics of the
engineering tool, and take action.
• If the number of device stations per network is more than the maximum number
of connectable stations, reduce it so that it does not exceed the maximum
number.
• Correct "Target Station" of communication test, and retry the operation.
• "Communication Test" cannot be executed for own station and relay sending
station.
• 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 are connected properly.
Please consult your local Mitsubishi representative.
• Change the IP address, station number, or network number of the target station
of the communication test.
• Check if the network configuration setting is correctly set in the master station
within the same network as the target station of the communication test.
