4.5 List of Error Codes
D0A4H to
D0A6H
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.
D0C0H Reserved station specification was performed again
during processing of the specification.
Retry the operation after a while.
D0C1H Temporary reserved station cancel specification was
performed again during processing of the
specification.
Retry the operation after a while.
D0C4H Temporary error invalid station setting was performed
again during processing of the setting.
Retry the operation after a while.
D0C5H Temporary error invalid station setting cancel
specification was performed again during processing
of the specification.
Retry the operation after a while.
D0D0H Station number setting of the other stations has failed. Retry the operation after a while.
D200H When the transient transmission was executed, data
was received twice.
• Check the network status using the CC-Link IE Field
Network diagnostics of the engineering tool, and
take action.
• Check if the switching hub and the cables at the
request source are connected properly.
• If the request source is on another network, check if
the routing parameters are set correctly, and take
action.
D202H The send buffer is full. • 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.
D203H The number of read data or write address of the
transient transmission is incorrect.
Correct the read data or write address at the transient
request source, and retry the operation.
D204H The network number of transient transmission is
incorrect.
• Correct the network number at the request source,
and retry the operation.
• If the request source is on another network, check if
the routing parameters are correctly set.
D205H The target station number of transient transmission is
incorrect.
Correct the target station number at the request
source, and retry the operation.
D206H The network number of transient transmission is
incorrect.
• Correct the network number at the request source,
and retry the operation.
• If the request source is on another network, check if
the routing parameters are correctly set.
D207H • In transient transmission, the number of relay to
other networks exceeded seven.
• The transient transmission was performed from the
standby system of the redundant system.
• Change the system configuration so that the
number of relay stations may be seven or less.
• Check if "Routing Setting" of "CPU Parameter" is
correctly set.
• Perform the transient transmission from the control
system.
D208H The network number of transient transmission is
incorrect.
• Correct the network number at the request source,
and retry the operation.
• If the request source is on another network, check if
the routing parameters are correctly set.
D209H The target station number of transient transmission is
incorrect.
Correct the target station number at the request
source, and retry the operation.
D20AH The target station number of transient transmission is
incorrect.
Correct the target station number at the request
source, and retry the operation.
D20BH When there was no master station, specified master
station was specified for transient transmission.
C
o
rrect the target station number at the request
source, and retry the operation.
D20CH When there was no master station, current master
station was specified for transient transmission.
Correct the target station number at the request
source, and retry the operation.
