(2) List of error codes (D000H to DFFFH (D529H and D52BH excluded))
While any of these errors occurs, the ERR. LED does not turn on. Based on the behavior of the D LINK LED at
the occurrence of an error, the errors are classified into two types, each of which requires different
troubleshooting.
(a) Communication errors where the D LINK LED flashes or turns off
This type of communication error results in the D LINK LED flashing or being turned off. Troubleshoot the
problem with the CC-Link IE Field Network diagnostics. (Page 229, Section 8.4.3)
Error code
Error name

D0E0H
Station type mismatch
D0E1H
Own station reserved
Station No. already in
D0E2H
use (own station)
Own station No. out of
D0E3H
range
Station number switch
D72AH
out of range (a value
other than 1 to 120)
(b) Communication errors where the D LINK LED does not change
This type of communication error results in no change of the D LINK LED. These errors are not shown in CC-
Link IE Field Network diagnostics because they are automatically recovered after the occurrence.
Troubleshooting them requires the error history to be read out. (Page 267, Section 11.1 (1))

When multiple errors have occurred, only the latest error code is stored in Latest error code (RWr0) or Latest warning code
(RWr2).
The errors that occurred in the past can be checked with the error history of the engineering tool.
For the error history, refer to the following.
• Checking with the command execution of slave station (Page 267, Section 11.1 (1))
• Error history (address: A00H to FFFH) (Page 363, Appendix 3 (69))

Description and cause
The network parameter is invalid or
outside the range.
The network parameter is invalid or
outside the range.
The network parameter is invalid or
outside the range.
The network parameter is invalid or
outside the range.
A value other than 1 to 120.is set as a
station number.
Description and cause
The transient data request command is
invalid.
The transient transmission is overloaded
and the receive buffer of the own station
is full.
Action
Change the station type of the module to the remote device station
in the network configuration settings of the master station.
• Cancel the reserved station specification in the network
configuration settings of the master station.
• Change the station number of the module to a station number
that is not reserved.
• Set a unique station number.
• After taking the above action, turn off and on or reset all the
stations where this error has been detected.
Add the station information of the module in the network
configuration settings of the master station.
Set a station number in the range of 1 to 120.
Action
Correct the request command at the request source, and retry the
operation.
• Check the network status using the CC-Link IE Field Network
diagnostics of the engineering tool.
• Send transient data to the own station at intervals.
