6.2.5 CANopen
Symptom Check
The CANopen bus is ‘passive’ This means that the internal CAN controller in the
NextMove ESB-2 is experiencing a number of Tx and/or
Rx errors, greater than the passive threshold of 127.
Check:

12-24 V is being applied to pin 5 of the RJ45 CAN
connector, to power the opto-isolators.

There is at least one other CANopen node in the
network.

The network is terminated only at the ends, not at
intermediate nodes.

All nodes on the network are running at the same baud
rate.

All nodes have been assigned a unique node ID.

The integrity of the CAN cables.
The NextMove ESB-2 should recover from the ‘passive’
state once the problem has been rectified (this may take
several seconds).
The CANopen bus is ‘off’ This means that the internal CAN controller in the
NextMove ESB-2 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:

12-24 V is being applied to pin 5 of the RJ45 CAN
connector, to power the opto-isolators.

There is at least one other CANopen node in the
network.

The network is terminated only at the ends, not at
intermediate nodes.

All nodes on the network are running at the same baud
rate.

All nodes have been assigned a unique node ID.

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 ESB-2.
