Response Codes
Section 6-7
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: Destination node 
error
01
Destination node not part of Network
Add to Network.
02
No node with the specified node 
address
Check the destination 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, destination node busy
Increase the number of transmit retry 
attempts or re-evaluate the system so that 
the destination node is not so busy receiv-
ing 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 destination 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.
04: Not executable
01
An undefined command has been 
used.
Check the command code and be sure that 
the Unit supports it.
02
