D20DH Transmission completion wait timeout has occurred in
transient data 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.
D20EH The header information of transient transmission is
incorrect.
Correct the header information at the request source,
and retry the operation.
D20FH In transient transmission, the command which cannot
be requested to all or a group of stations was executed
with all stations specification or group specification.
Check that the command can be requested to all or a
group of stations at the request source, and retry the
operation.
D210H The target station number of transient transmission is
incorrect.
Correct the header information at the request source,
and retry the operation.
D211H Transient transmission was performed when the
station number of the own station has not been set yet.
Set the station number using the UINI instruction, and
perform transient transmission again.
D212H Transient transmission failed. • Check if the switching hub and the cables at the
request source are connected properly.
• 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.
D213H • The command of transient transmission is incorrect.
• The CC-Link IE Field Network diagnostics was used
for the network to which the relay receiving station
belongs.
• Correct the request command at the request
source, and retry the operation.
• Review the connection destination so that the
CCLink IE Field Network diagnostics is used for the
network to which the relay sending station belongs.
D214H The data length of transient transmission is incorrect. Correct the data length at the transient request
source, and retry the operation.
D215H The module operation mode is set to a mode in which
transient transmission cannot be executed.
Change "Module Operation Mode" in "Application
Settings" to "Online", and retry the operation.
D216H The command of transient transmission is incorrect. Correct the request command at the request source,
and retry the operation.
D217H The command of transient transmission is incorrect. Correct the request command at the request source,
and retry the operation.
D218H The number of read/write data of transient
transmission is incorrect.
Correct the number of read or write device data at the
request source, and retry the operation.
D219H The attribute code of transient transmission is
incorrect.
Correct the attribute code at the request source, and
retry the operation.
D21AH The access code of transient transmission is incorrect. Correct the access code at the request source, and
retry the operation.
D21BH A transient transmission error was detected. • Abnormal transient data were issued from the CPU
module.
• Replace the CPU module and retry the operation.
• If the error occurs again even after taking the above,
please consult your local Mitsubishi representative.
D21CH A transient transmission error was detected. • Abnormal transient data were issued from the CPU
module.
• Replace the CPU module and retry the operation.
• If the error occurs again even after taking the above,
please consult your local Mitsubishi representative.
