accessed when the data link was not performed.
-28151 9209H ■Abnormal data reception error
Abnormal response data received.
■WDT error
-28158 9202H
WDT (system/user) error occurred.
-28410 9106H ■Target CPU busy error
The target CPU module is busy.

An unsupported request was issued to the target CPU module.
-28413 9103H ■Target CPU down error
The target CPU module is down.
■Target CPU abnormal start error
-28414 9102H
A request was issued to the CPU module which is not operating
normally.
-28415 9101H ■Target CPU major error
A request was issued to the CPU module in which a major error
occurred.
-28416 9100H ■Target CPU mounting error
A request was issued by specifying the CPU number in the state
where no CPU module is mounted.
-28624 9030H ■Function unsupported error
• Any processing was performed to the module which does not
support the station-based block data assurance function for
cyclic data.
• Any processing was performed to the module on which the
station-based block data assurance function for cyclic data is
not set.
• An attempt was made to access a module which was not
controlled by the host CPU module.
-28625 902FH ■Intelligent function module offline error
An attempt was made to access the intelligent function module
when it was offline.
■Control data setting value out of range error
-28626 902EH
The specified control data is out of range.
-28627 902DH ■Transient unsupported error
Transient transmission cannot be performed via the specified
communication route and target. (Another station was specified
when the station number of the own station is '64' during CC-
Link communication.)
■Pointer address specification error
-28628 902CH
An incorrect address was specified to the argument pointer.
-28629 902BH ■WDT not started error
An attempt was made to reset a WDT before starting it.
Corrective action
Check the device points.
Refer to the user's manual of the access target CPU module.
Check the network number and station number of the request
destination.
Check the settings of routing parameters.
• Check the specified start device number and size, or the
device range of the parameter for the master station.
• Restart the date link.
(Note that data is written/read despite this error, however, the
contents of the data will not be guaranteed.)
Check if an error occurred in the request destination CPU
module or link module.
(If the status is normal, resend the request.)
Reset the CPU module, or turn the power OFF and ON to reset
the C intelligent function module.
• Add the processing to wait for the completion of the target
operation or to retry the operation in the user program.
• Increase the timeout time specified to the argument in the
user program.
Change the target CPU module specified in the user program.
Check the operating status of the target CPU and troubleshoot
the error according to the user's manual of the CPU module.
Check the operating status of the target CPU and troubleshoot
the error according to the user's manual of the CPU module.
Check the operating status of the target CPU and troubleshoot
the error according to the user's manual of the CPU module.
• Check the mounting condition of the target CPU module.
• Change the target CPU number specified in the user
program.
• Check if the target CC-Link module supports the station-
based block data assurance function for cyclic data.
• Check if the station-based block data assurance function for
cyclic data is set for the target module.
• Check if the control CPU of the target module is the host CPU
module.
Check the status of the intelligent function module and access
the module while it is online.
Check the value set to the control data of the user program.
• Check the communication route and target which support the
transient request.
• Change the station number of the own station.
Check the address of the specified pointer.
Reset the WDT after starting it.
