Appendix 1.4 Error Code Returned To Peripherals - Mitsubishi Electric MELSEC Q Series User Manual

Appendix 1.4
The C Controller module returns an error code to the request source when any error occurs during communication
request from any of the following:
• Peripheral device (such as GOT)
• Intelligent function module
• Network system
● Error codes shown in this section are not for the errors that can be detected by the self-diagnostic function of the C
Controller module. Therefore, none of these are stored in the special register, Diagnostic error (SD0).
● When the request source is a peripheral device, a message or an error code will be shown on the peripheral device.
When the request source is an intelligent function module or a network system, an error code for the requested
processing will be returned to the request source.
The following table lists the error codes detectable by the C Controller module (4001
actions.
Error code
4001
H
Execution of an unsupported request was attempted.
4002
H
The requested task cannot be executed because the C Controller module is in the
4010
H
RUN status.
4030 The specified device name is not valid.
H
4031 The specified device No. is out of range.
H
4040 The specified intelligent function module cannot handle the request.
H
The access range exceeded the buffer memory range of the specified intelligent
function module.
4041
H
The buffer memory address, to which no access is allowed, was specified.
4042 Unable to access the specified intelligent function module.
H
4043 The specified intelligent function module does not exist.
H
408B The remote request cannot be executed.
H
In a multiple CPU system, the operation was performed for an intelligent function
414A
H
module that is not in the controlled group.
The buffer memory address, to which no access is allowed, was specified.
414C
H
The CPU shared memory address, to which no access is allowed, was specified.
The requested task cannot be executed because the online module change function is
4201
H
enabled in the multiple CPU parameter settings.
• 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
4A00
H
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.
4A01 The network of the network No. set for the routing parameter does not exist.
H
4A02 Unable to access the specified station.
H
Failure has occurred at the access target or a relay station. Or, the specified
4B00
H
connection destination (I/O number of the requested module) is incorrect.
4B01 The target is not CPU No.1 of the multiple CPU system.
H
4B02 The request is not addressed to a CPU module.
H
• The specified module version does not support the route.
4B03
H
• The communication target CPU module is not mounted.

Corrective action
Check the CPU module model selected for the peripheral device.
Set the C Controller module to STOP.
Confirm the specified device name.
• Check the specified device No.
• Check the device settings of the C Controller module.
Check if the specified intelligent function module has a buffer memory.
Check the start address and the number of access points, and make an
access within the range allowed for the intelligent function module.
Check the buffer memory address, and correct it to retry.
• Check if the specified intelligent function module is operating normally.
• Check the specified module for hardware failure.
Check the I/O number of the specified intelligent function module.
• 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.
Retry the operation from the control CPU of the target module.
Check the buffer memory address, and correct it to retry.
Check the CPU shared memory address, and correct it to retry.
Do not make the request, or disable the online module change function and
then execute the request again.
• 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.
Check the routing parameter set for the relevant stations, and correct it.
• Check the network module or link module for failure or offline mode.
• Check the specified network No. and station No. for an error.
• 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).
Execute the request to CPU No.1 of the multiple CPU system.
Perform the operation to a module that can execute the specified function.
Check if the specified route is supported.
