5.8 CANopen – node ID scan
In the operating mode "CANopen" (selected via the menu item "Settings"), the
CANcheck scans for CANopen node IDs transmitted via the CAN network. The
CANcheck only analyzes the following identifiers:
•
Identifier that the node transmits with the "Node guarding protocol" or
"Heartbeat protocol"
•
Identifier that the node transmits with access via the first server SDO and
which is formed according to the "Pre-defined connection set"
because the node ID is clearly contained in these identifiers. The condition for the
recording of node IDs is therefore that the relevant messages are transmitted via
the bus. During the scan time (the default setting is 10 s) the CANcheck gener-
ates a list of node IDs and counters that state how often the node IDs were re-
corded.
If the above-mentioned identifiers are repeated in your CAN network with a pe-
riod of more than 10 s, you must change the scan time. This is done via the me-
nu item "Settings".
The length of the list with node IDs and counters is limited to the value given in
section 10.1.
For the node ID scan, you can connect the CANcheck to the CAN network at any
point:
•
If there is a free SUB-D9 socket in the CAN network, you can connect the
CANcheck to this socket via the 1-to-1 cable.
•
If this is not the case, you can loop in the CANcheck between any CAN node
and the CAN network via the Y cable.
Please put the CAN network into operation before you start the node ID scan.
Please select the menu item "Node ID scan" with the keys UP and DOWN and
press the OK key.

During the measurement, first the baudrate is detected and the relevant message
appears. Then the node ID scan is carried out and a further message appears.
