Response Codes and Troubleshooting
The table below lists response codes (main and sub-codes) returned after
execution of the FINS commands, the probable cause of errors, and recom-
mended remedies.
Upon receipt of some commands, the remote node will issue a request to
another node; the other node is referred to as the third node.

00: Normal completion
00
---
---
01
Service was interrupted
Check the contents of the destination trans-
mission area of third node.
Check the data link status.
01: Local node error
01
Local node not part of Network
Add to Network.
02
Token time-out, node address too large Set the local node’s node address below
the maximum node address.
03
Number of transmit retries exceeded
Check communications with ECHOBACK
TEST. If the test fails, check network.
04
Maximum number of frames exceeded
Either check the execution of events in the
network and reduce the number of events
occurring in one cycle, or increase the max-
imum number of frames.
05
Node address setting error (range)
Correctly set the Controller Link BIOS /N
option. Make sure the node address is
within specified range and that there are no
node addresses that are set twice.
06
Node address duplication error
Make sure that there are no node
addresses that are set twice.
02: Remote node error
01
Remote node not part of Network
Add to Network.
02
No node with the specified node
address
Check the remote node’s node address.
03
Third node not part of Network
Check the third node’s node address.
Broadcasting was specified.
Check the control data and specify only one
node as the third node.
04
Busy error, remote node busy
Increase the number of transmit retry
attempts or re-evaluate the system so that
the remote node is not so busy receiving
data.
05
Response time-out, message packet
was corrupted by noise
Increase the number of transmit retry
attempts.
Response time-out, response watch-
dog timer interval too short
Increase the value for the response watch-
dog timer interval in the control data.
Frame lost in transmission
Check the error log and correct the process.
03: Communications con-
troller error
01
Error occurred in the communications
controller, ERC indicator is lit
Take corrective action, referring to commu-
nications controller errors and remedies
table at end of this section
02
CPU Unit error occurred in the PLC at
the remote node
Clear the error in the CPU Unit (refer to the
PLC’s operation manuals)
03
A controller error has prevented a nor-
mal response from being returned.
Check network communications status and
reset the controller board. If the error still
exists, replace the controller board.
04
Unit address setting error
Make sure the Unit address is within the
specified range and that there are no node
addresses that are set twice.
