TROUBLESHOOTING
Table 16.11 Error codes that may be detected during communication (continued)
Error code (hexadecimal) Error Action
408BH The remote request cannot be executed.
• Set the C Controller module into the remote-
request-executable state and then make the
request again.
• For a remote reset operation, enable the
remote reset with the parameter.
414AH
In a multiple CPU system, the operation was
performed for an intelligent function module
that is not in the controlled group.
Retry the operation from the control CPU of
the target module.
414CH
The buffer memory address, to which no
access is allowed, was specified.
Check the buffer memory address, and
correct it to retry.
4201H
The requested task cannot be executed
because the online module change function is
enabled in the multiple CPU parameter
settings.
Do not make the request, or disable the
online module change function and then
execute the request again.
4A00H
Unable to access the specified station
because no routing parameters are set for the
source and relay CPU modules.
In the case of a relay through a multiple CPU
system, the control CPU of the relaying
network module has not been activated.
In a redundant system configuration, an
access to another station through a network
module was performed while system A or B is
not defined.
• To access the specified station, set the
routing parameters for the relevant stations.
• Wait a little while, and retry. Or, after
confirming activation of the relay system,
start the communication.
• In the case of a redundant system
configuration, activate systems A and B
normally with a tracking cable, and then start
communication again.
4A01H
The network of the network No. set for the
routing parameter does not exist.
Check the routing parameter set for the
relevant stations, and correct it.
4A02H Unable to access the specified station.
• Check the network module or link module for
failure or offline mode.
• Check the specified network No. and station
No. for an error.
4B00H
Failure has occurred at the access target or a
relay station. Or, the specified connection
destination (I/O number of the requested
module) is incorrect.
• Identify the error occurred at the specified
access target or a relay station on the route
to the access destination, and take action.
• Check the access target specification (I/O
number or station number of the request
target module).
4B01H
The target is not CPU No.1 of the multiple
CPU system.
Execute the request to CPU No.1 of the
multiple CPU system.
4B02H
The request is not addressed to a CPU
module.
Perform the operation to a module that can
execute the specified function.
4B03H
The specified module version does not
support the route.
The communication target CPU module is not
mounted.
Check if the specified route is supported.
