10.5 List of Error Codes
D909H The header information of transient transmission
is incorrect.
Correct the header information at the transient request source, and
retry the operation.
D90AH During execution of the communication test, the
test was retried.
Check the network status using the CC-Link IE TSN/CC-Link IE Field
diagnostics of the engineering tool, and take action. Then, retry the
operation.
D90BH The number of stations that communicate in the
network is out of the specification range.
• Check the network status using the CC-Link IE TSN/CC-Link IE
Field diagnostics of the engineering tool, and take action.
• If the number of device stations per network is more than 120,
reduce it to 120 or less.
D90CH The communication destination specified for the
communication test is incorrect.
• Correct "Target Station" of communication test, and retry the
operation.
• Do not execute the communication test for own station and relay
sending station. Set "Target Station" to other than own station and
relay transmission station.
• The target station is mounted on the same CPU module as the
connected station (own station). Do not execute the
communication test for a station on the same CPU module as the
connected station (own station).
D90DH An error was detected in the network module. Please consult your local Mitsubishi representative.
D912H Transient transmission sending failed. • Lower the transient transmission usage frequency, and retry the
operation.
• Check if the industrial switch and the Ethernet cables are
connected properly.
D913H
to
D917H
An error was detected in the network module. Please consult your local Mitsubishi representative.
D919H No response from the target station of the
communication test.
• Correct the network number, station number, or IP address for 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.
• When "IP Address" is selected for "Communication Method",
"Communication Test" cannot be executed for stations on
networks different from that of the connected station (own station).
Change "Communication Method" to "Network No./Station No.".
DA00H An error was detected in the network module. Please consult your local Mitsubishi representative.
DA10H
to
DA17H
An error was detected in the network module. Please consult your local Mitsubishi representative.
DA19H An error was detected in the network module. Please consult your local Mitsubishi representative.
DA1AH System error Please consult your local Mitsubishi representative.
DA1BH A dedicated instruction which the target station
does not support was executed.
• Change the target station at the station that executed the READ/
SREAD/WRITE/SWRITE/SEND/ instruction.
• Correct the network number and station number/IP address of the
target station of the dedicated instruction.
DA1CH The target station of the READ/SREAD/WRITE/
SWRITE/SEND instruction does not exist.
If the target station of the READ/SREAD/WRITE/SWRITE/SEND
instruction is disconnected, execute the dedicated instruction again
after return of the target station.
DB00H The station numbers of 121 stations or more are
specified.
Check station numbers.
DC00H The setting value is incorrect. Write again after correcting the setting value.
DC01H The setting value was not written correctly. • Write again.
• If the error occurs again even after taking the above, please
consult your local Mitsubishi representative.
