code
Sub-
Local node not part of Network.
Token time-out, node number too
high.
Number of transmit retries exceeded.
Maximum number of frames
exceeded.
Node number setting error (range).
Node number duplication error.
Destination node not part of Network.
No node with the specified node
number.
Third node not part of Network.
Busy error, destination node busy.
Response time-out, message packet
was corrupted by noise.
Response time-out, response watch-
dog timer interval too short.
Error occurred in the communications
controller, ERC indicator is lit.
CPU Unit error occurred in the PC at
the destination node.
Node number setting error.
An undefined command has been
used.
Cannot process command because
the specified unit model or version is
wrong.
Destination node number is not set in
the routing table.
Routing table isn’t registered.
Routing table error.
The maximum number of relay nodes
(2) was exceeded in the command.
Probable cause
Add to Network.
Set the local node’s node number below
the maximum node number.
Check communications with internode
echo test. If the test fails, check network.
Either check the execution of events in the
network and reduce the number of events
occurring in one cycle, or increase the
maximum number of frames.
Make sure the node number is within
specified range and that there are no
duplicate node numbers.
Make sure that there are no duplicate node
numbers.
Add to Network.
Check the destination node’s node
number.
Check the third node’s node number.
Increase the number of transmit retry
attempts or re-evaluate the system so that
the destination node is not so busy
receiving data.
Increase the number of transmit retry
attempts. Perform an internode echo test
to check noise level.
Increase the value for the response watch-
dog timer interval.
Take corrective action, referring to
communications controller errors and
remedies table at end of this section.
Clear the error in the CPU Unit (refer to the
PC’s Operating Manual)
Make sure the node number is within
specified range and that there are no
duplicate node numbers.
Check the command code.
Check the unit model and version.
Set the destination node number in the
routing table.
Set the source nodes, destination 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.
