Function unsupported error
-28624 9030H
• 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.
Intelligent function module offline error
-28625 902FH
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.
Transient unsupported error
-28627 902DH
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.)
-28628 902CH Pointer address specification error
An incorrect address was specified to the argument pointer.
WDT not started error
-28629 902BH
An attempt was made to reset a WDT before starting it.
WDT startup error
-28630 902AH
An attempt was made to start WDT while the other WDT is
starting up.
Buffer access range error
-28631 9029H
• The specified offset is out of range.
• The specified offset and its size is out of range.

• No accessible module is mounted on the specified I/O
number.
Non-controlled module read error
-28633 9027H
An attempt was made to access a module which is not
controlled by the host CPU when reading data from a non-
controlled module is not allowed.
-28634 9026H Intelligent function module down error
The intelligent function module has an error.
Intelligent function module error
-28635 9025H
No intelligent function module is mounted on the accessed slot
with the specified I/O number.
-28636 9024H Control bus error
The control bus to the intelligent function module has an error.
Multiple CPU unsupported operation error
-28638 9022H
-28640 9020H STOP/PAUSE error
The request of output or of writing to the buffer memory is issued
when the operating status of the CPU module is STOP or
PAUSE.
I/O assignment error
-28653 9013H
• An attempt was made to read the input value (X) from an
output module.
• An attempt was made to write the output value (Y) to an input
module.
• An attempt was made to read the output value (Y) from an
input module.
Non-controlled module write error
-28654 9012H
An attempt was made to access a module which is not
controlled by the host CPU.
Access size error
-28660 900CH
The specified size is out of range.
Corrective action
• 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.
• 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.
Start the WDT after stopping the WDT which is starting up.
• Check the specified offset.
• Check the specified buffer size.
• Check the offset and its size.
Check the specified I/O number.
Check if the control CPU of the specified module is the host
CPU module (C Controller module/PC CPU module/
MELSECWinCPU module).
• Check the mounting condition of the target CPU module.
• Replace the intelligent function module or base unit.
• Check the specified I/O number and the slot.
• Check the mounting condition of the target CPU module.
• Check if an error occurs in the bus master CPU (CPU No.1) in
the multiple CPU system.
• Check the mounting condition of the target CPU module.
• Replace the intelligent function module or base unit.
Reset the bus master CPU (CPU No.1).
Change the operation status of the CPU module to RUN.
Check the input number (X) and output number (Y).
Check if the control CPU of the specified module is the host
CPU module (C Controller module/PC CPU module/
MELSECWinCPU module).
Review the specified offset and size.
