Communication errors where the D LINK LED does not change
The following table lists the communication errors of the 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 TSN/CC-Link IE Field diagnostics of the engineering tool. Troubleshoot these errors by executing "Error history read"
in the "Network Configuration Settings".

• The error codes of the CC-Link IE Field Network are not accompanied by safety error subset codes. In the
error classification and error item number, 0 is stored.
• When multiple errors have occurred, only the latest error code is stored in Error code. However, when a
moderate error occurs during a major error occurrence, the error code of the major error will remain in Error
code. The errors that occurred before can be checked by executing "Error history read" of the "Network
Configuration Settings". For the error history, refer to the following.
Page 134 Checking with "Command Execution of Device Station"
• Error code details 1 to Error code details 10 for communication errors are fixed to 0.
• If the same error occurs successively, only the error that occurs first is stored to the error history. (Only for
the NZ2GFSS2-32D-S1)
• For the NZ2GFSS2-8D-S1, NZ2GFSS2-8TE-S1, or NZ2GFSS2-16DTE-S1, if the same error occurs
successively, only the latest error is stored to the error history. The order of generation for the latest error
does not change. (If the error occurs at powering off and on or after remote reset, the previous error is also
stored to the error history. The order of generation for the latest error changes.)
Error name Description and cause
Transient data request The transient data request
command error command is incorrect.
Receive buffer full The target station is overloaded
and cannot receive transient data.
Transient data length The received transient data is
error incorrect.
Transient data divided The divided transient data were
error received.
Action
Correct the request command at the transient request
source, and resend the corrected request command.
• Check the network status using CC-Link IE Field
Network diagnostics of the engineering tool to take
the appropriate action.
• When the target station is overloaded and cannot
receive transient data, send the data to the target
station after a while.
Correct the number of data points (frame length) at the
transient request source, and resend the corrected
transient data.
Send the transient data that is not divided.
