Sub-
code
Local node not part of Network
Token time-out, node address too large Set the local node’s node address below
Number of transmit retries exceeded
Maximum number of frames exceeded Either check the execution of events in the
Node address setting error (range)
Node address duplication error
Destination node not part of Network
No node with the specified node
address
Third node not part of Network
Broadcasting was specified.
Busy error, destination node busy
Response time-out, message packet
was corrupted by noise
Response time-out, response watch-
dog timer interval too short
(If a large number of data links is used,
the response monitor time will be
shorter than the communications cycle
time.)
Frame lost in transmission
Error occurred in the communications
controller, ERC indicator is lit
CPU Unit error occurred in the PLC at
the destination node
A controller error has prevented a nor-
mal response from being returned.
Unit address setting error
An undefined command has been
used.
Cannot process command because the
specified unit model or version is
wrong.
Probable cause
Add to Network.
the maximum node address.
Check communications with ECHOBACK
TEST. If the test fails, check network.
network and reduce the number of events
occurring in one cycle, or increase the max-
imum number of frames.
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.
Make sure that there are no node
addresses that are set twice.
Add to Network.
Check the destination node’s node address.
Check the third node’s node address.
Check the control data and specify only one
node as the third node.
Increase the number of transmit retry
attempts or re-evaluate the system so that
the destination node is not so busy receiv-
ing data.
Increase the number of transmit retry
attempts.
Increase the value for the response watch-
dog timer interval in the control data.
Check the error log and correct the process.
Take corrective action, referring to commu-
nications controller errors and remedies
table at end of this section.
Clear the error in the CPU Unit (refer to the
PLC’s operation manuals).
Check network communications status and
reset the controller board. If the error still
exists, replace the controller board.
Make sure the Unit address is within the
specified range and that there are no node
addresses that are set twice.
Check the command code and be sure that
the Unit supports it.
Check the unit model and version.
