(HEX)
Error description Corrective action
17233
(0x4351)
The instruction cannot be executed on the specified target CPU
module.
(1) The instruction name is wrong.
(2) A non-supported instruction was executed on the target CPU
module.
Check and revise the program to a proper user
program.
17234
(0x4352)
The number of devices of the specified instructions is wrong.
Check and revise the program to a proper user
program.
17235
(0x4353)
An inapplicable device was specified in the specified instruction.
Check and revise the program to a proper user
program.
17236
(0x4354)
A non-supported string was specified in the specified instruction.
Check and revise the program to a proper user
program.
17237
(0x4355)
The number of write data is out of the range of 1 to 20.
Check and revise the program to a proper user
program.
18944
(0x4A00)
Network No. or station No. is incorrect.
Routing parameter does not exist in other network settings, or the
module with relay network No. and station No. specified in the routing
parameter settings is not mounted.
Check the specified network No. and station
No.
Check the routing parameter settings.
19200
(0x4B00)
An error was detected in the target.
Check the target.
Confirm the error occurred in the target or relay
station, and then take a corrective action.
19201
(0x4B01)
The target is not the bus master CPU.
If the target is not the bus master CPU (CPU
1), it cannot execute remote reset.
19203
(0x4B03)
Unsupported communication path error
The request cannot be executed via the specified communication
path/target.
Check the communication path/target that
supports the request.
Do not issue a request that has generated an
error to a C Controller module or PC CPU.
19457
(0x4C01)

Check the user program on C Controller
module.
19458
(0x4C02)
Motion SFC program No. error (the error code returned by the Motion
CPU)
Refer to the manual of the Motion CPU currently used.
Check the user program on C Controller
module.
19460
(0x4C04)
Axis No. specified in SVST function is invalid. (the error code
returned by the Motion CPU)
Refer to the manual of the Motion CPU currently used.
Check the user program on C Controller
module.
19461
(0x4C05)
Axis No. specified in CHGA function is invalid. (the error code
returned by the Motion CPU)
Refer to the manual of the Motion CPU currently used.
Check the user program on C Controller
module.
19462
(0x4C06)
Axis No. specified in CHGV function is invalid. (the error code
returned by the Motion CPU)
Refer to the manual of the Motion CPU currently used.
Check the user program on C Controller
module.
19463
(0x4C07)
Axis No. specified in CHGT function is invalid. (the error code
returned by the Motion CPU)
Refer to the manual of the Motion CPU currently used.
Check the user program on C Controller
module.
19464
(0x4C08)
A total of 32 or more instructions are simultaneously requested to the
Motion CPU from the programmable controller CPU/C Controller
module, and the Motion CPU cannot process them. (the error code
returned by the Motion CPU)
Refer to the manual of the Motion CPU currently used.
Check the user program on C Controller
module.
