16.4.2 Error codes and actions (for errors occurred in communication)
The C Controller module returns an error code to a request source if an error occurs at the
time of a communication request from the following.
• Peripheral device
• Intelligent function module
• Network system
POINT
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 (4000H to
4FFF
H) and troubleshooting actions.

Table 16.11 Error codes that may be detected during communication
Error code (hexadecimal) Error Action
4001H
Execution of an unsupported request was
attempted.
Check the CPU module model selected for
the peripheral device.
4002H
4010H
The requested task cannot be executed
because the C Controller module is in the
RUN status.
Set the C Controller module to STOP.
4030H The specified device name is not valid. Confirm the specified device name.
4031H The specified device No. is out of range.
• Check the specified device No.
• Check the device settings of the C Controller
module.
4040H
The specified intelligent function module
cannot handle the request.
Check if the specified intelligent function
module has a buffer memory.
4041H
The access range exceeded the buffer
memory range of the specified intelligent
function module.
Check the start address and the number of
access points, and make an access within the
range allowed for the intelligent function
module.
The buffer memory address, to which no
access is allowed, was specified.
Check the buffer memory address, and
correct it to retry.
4042H
Unable to access the specified intelligent
function module.
• Check if the specified intelligent function
module is operating normally.
• Check the specified module for hardware
failure.
4043H
The specified intelligent function module does
not exist.
Check the I/O number of the specified
intelligent function module.
