True ➨ Correct the mail send information settings in the Setup (the user
data, error log information, or status data is not set in the send in-
formation).
22. Was it impossible to obtain the required information from the mail data?
True ➨ Correct the following errors.
Correct the user-generated mail address.
Check the user application to be sure that there is not too much
traffic at the Ethernet Unit.
23. End
24. Check the setting of the mail send timing in the Setup. The timing may not
be set or may be set longer than intended.
10-6 Troubleshooting with Response Codes
You can troubleshoot the errors in FINS communications from the response
codes when the SEND(090), RECV(098), or CMND(490) instructions have
been used. For the storage areas of the response codes refer to information
on page 90.
The table below lists response codes (main and sub-codes) returned after
execution of FINS commands, the probable cause of errors, and recom-
mended remedies. The response codes provided here are for the Ethernet
Unit. Refer to the FINS Command Reference Manual (W227) or the operation
manuals for the relevant Unit for further information on response codes.
The 6th, 7th, and 15th bits of the response codes have specific functions. The
6th bit will be ON when a non-fatal error has occurred in the PC at the remote
node; the 7th bit will be ON when a fatal error has occurred in the PC at the
remote node; and the 15th bit will be ON when a network relay error has
occurred. Refer to information given after the following table for more informa-
tion on relay errors.

error
03 Send error in local node was caused by
lack of available space in internal buffers.
Reduce the load (traffic) on the Ethernet Unit.
Check your user applications.
05 The network cannot be accessed because
the IP address setting is not correct.
Correct the local IP address.
07 The internal buffers are full because there
is too much traffic at the local node, pre-
venting data from being sent.
Correct the user application to reduce traffic at
the Ethernet Unit.
