Troubleshooting 7-7 MN1928
Symptom Check
The CANopen bus is
‘off’ This means that the internal CAN controller in the NextMove ES has
experienced a fatal number of Tx and/or Rx errors, greater than the
off threshold of 255.
At this point the node will have switched itself to a state whereby it
cannot influence the bus.
Check:
H
12-24 V is being applied to pin 5 of the RJ45 CAN
connector, to power the opto-isolators.
H
There is at least one other CANopen node in the
network.
H
The network is terminated
only
at the ends, not at
intermediate nodes.
H
All nodes on the network are running at the same
baud rate.
H
All nodes have been assigned a unique node ID.
H
The integrity of the CAN cables.
To recover from the ‘off’ state the bus must be reset. This can be
done using the Mint
BUSRESET
keyword, or by resetting the
NextMove ES.
The Manager node
cannot
scan/recognize a
node on the network
using the Mint
NODESCAN keyword.
Assuming that the network is working correctly (see previous
symptoms) and the bus is in an ‘Operational’ state, check the
following:
H
Only nodes that conform to DS401, DS403 and other
Baldor CANopen nodes are supported by the Mint
NODESCAN
keyword.
H
Check that the node in question has been assigned a
unique node ID.
H
The node must support the node guarding process.
NextMove ES does not support the Heartbeat
process.
H
Try power-cycling the node in question.
If the node in question does not conform to DS401 or DS403 and is
not a Baldor CANopen node, communication is still possible using a
set of general purpose Mint keywords. See the Mint help file for
further details.
The node has been
successfully
scanned /
recognized by the
Manager node, but
communication is still
not possible. For communication to be allowed, a connection must be made to a
node after it has been scanned.
H
Baldor controller nodes are automatically connected
to after being scanned.
H
Nodes that conform to DS401, DS403 must have the
connections made manually using the Mint
CONNECT
keyword.
If a connection attempt using CONNECT fails then it may be because
the node being connected to does not support an object which
needs to be accessed in order to setup the connection.
