Response Codes
This section describes the response codes returned with responses to FINS
commands. Response codes can be used to confirm normal completion of
command execution or to troubleshoot problems when commands fail. For fur-
ther troubleshooting information, refer to
of this manual and to the operation manuals for specific Units or
Systems.

Configuration
Response codes for FINS commands consist of two bytes that indicate the
result of executing a command. The structure of the response codes is shown
in the following diagram.
The main response code (MRES) in the first byte classifies the response and
the sub-response code (SRES) in the second byte indicates details under the
MRES classification.
If bit 7 of the first byte is ON, a network relay error has occurred. Refer to
for details on troubleshooting the error.
If bit 6 or 7 of the second byte is ON, an error has occurred in the PLC or com-
puter returning the response. Refer to the operation manual for the device
returning the response for details when troubleshooting the error.
