The following table lists the communication errors of CC-Link IE Field Network where the D LINK LED does not change at an
error. These errors are automatically eliminated after occurrence of an error. Therefore, they are not displayed in the CC-Link
IE Field Network diagnostics of the engineering tool. Troubleshoot these errors by executing "Error history read" from the
"Network Configuration Settings".
