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 72.
The table below lists response codes (main and sub-codes) returned after ex-
ecution of FINS commands, the probable cause of errors, and recommended
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 re-
mote 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 information on relay
errors.

01: Local node
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,
preventing data from being sent.
Correct the user application to reduce traffic at
the Ethernet Unit.
02: Remote node
error
01
IP address of remote node not set
correctly in IP address table or IP router
table.
Set IP address of remote node into IP address
table and, if internetwork transmission is
required, into the IP router table.
02
No node with the specified unit address.
Check the remote node’s unit address and
make sure the correct one is being used in the
control data.
05
Message packet was corrupted by trans-
mission error.
Check the protocol and controller status by
reading them with FINS commands. Increase
the number of transmit retry attempts.
Response time-out, response watchdog
timer interval too short.
Increase the value for the response monitor
time in the control data.
The transmission frame may be corrupted
or the internal reception buffer full.
Read out the error log and correct as required.
