4 TROUBLESHOOTING
4.5 List of Error Codes
D282H The receive queue is full. • Pause the transient transmission temporarily, and
retry the operation.
• Lower the transient transmission usage frequency,
and then perform again.
• Use the COM instruction to increase the frequency
of transient transmission.
• If the error occurs again even after taking the above,
please consult your local Mitsubishi representative.
D283H Transient transmission failed. • Check the network status using the CC-Link IE Field
Network diagnostics of the engineering tool, and
take action.
• Connect the cable to the other port on the request
source, and retry the operation.
• Lower the transient transmission usage frequency,
and then perform again.
D284H The target execution module in the SLMP data is
incorrect.
Correct the target execution module in the SLMP
header, and retry the operation.
D2A0H The receive buffer is full. • Check the network status using the CC-Link IE Field
Network diagnostics of the engineering tool, and
take action.
• When the target station or the relay station is
overloaded and cannot receive transient data, send
the data to the target/relay station after the load on
the station is reduced.
D2A1H The send buffer is full. • 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.
D2A2H Transmission completion wait timeout has occurred in
transient transmission.
• 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.
D2A3H The data length in the transient transmission frame is
incorrect.
Correct the number of data (frame length) at the
request source, and retry the operation.
D2A4H The header information in the transient transmission
frame is incorrect.
Correct the header information at the request source,
and retry the operation.
D2A5H The target station number in the transient transmission
frame is incorrect.
Correct the target station number at the request
source, and retry the operation.
D2A6H The request source number in the transient
transmission frame is incorrect.
Correct the request source number at the request
source, and retry the operation.
D2A7H The header information in the transient transmission
frame is incorrect.
Correct the header information at the request source,
and retry the operation.
D2A8H The header information in the transient transmission
frame is incorrect.
Correct the header information at the request source,
and retry the operation.
D2A9H The target network number in the transient
transmission frame is incorrect.
Correct the target network number at the request
source, and retry the operation.
D2AAH The target station number in the transient transmission
frame is incorrect.
Correct the target station number at the request
source, and retry the operation.
D2ABH The request source network number in the transient
transmission frame is incorrect.
Correct the network number of the request source at
the request source, and retry the operation.
D2ACH The request source station number in the transient
transmission frame is incorrect.
Correct the station number of the request source at
the request source, and retry the operation.
D2ADH The data length in the transient transmission frame is
incorrect.
Correct the number of data (frame length) at the
request source, and retry the operation.
D2AEH The target station number in the transient transmission
frame is incorrect.
• The own station received transient data addressed
to another station. Correct the network and target
stat
i
on numbers, and retry the operation.
• Check if "Routing Setting" of "CPU Parameter" is
correctly set, and take action.
