Response Codes
Main code
02: Remote node error
03: Communications con-
troller error
04: Not executable
05: Routing error
180
Sub- Probable cause
code
01 Remote node not part of Network
02 No node with the specified node
address
03 Third node not part of Network
Broadcasting was specified.
04 Busy error, remote node busy
05 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
01 Error occurred in the communications
controller, ERC indicator is lit
02 CPU Unit error occurred in the PLC at
the remote node
03 A controller error has prevented a nor-
mal response from being returned.
04 Unit address setting error
01 An undefined command has been
used.
02 Cannot process command because the
specified unit model or version is
wrong.
01 Remote node address is not set in the
routing table.
02 Routing table isn't registered.
03 Routing table error
04 The maximum number of relay nodes
was exceeded in the command.
Remedy
Add to Network.
Check the remote 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 remote node is not so busy receiving
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.
Set the remote node address in the routing
table.
Set the local nodes, remote nodes, and
relay nodes in the routing table.
Set the routing table correctly.
Redesign the network or reconsider the
routing table to reduce the number of relay
nodes in the command. Use a CS-series
CPU Unit with unit Ver. 2.0 or later with CX-
Programmer Ver. 4.0 or later to send com-
mands across three or more network levels.
