(2) Error code list (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 152, Section 8.19)

(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 168, Section 11.1 (1))

For two or more errors, only the latest error code is stored in Latest error code (RWr0) or Latest warning code (RWr1).
The errors that have occurred in the past can be checked in the error history of the engineering tool.
For the error history, refer to the following:
• Checking by executing a command of the slave station ( Page 168, Section 11.1 (1))
• Error history data ( Page 222, Appendix 3 (23))
