5.9 Bus
load
The CANcheck determines the bus load by recording all messages on the CAN
network during the scan time. The default setting is 10 s. When determining the
bus load the CANcheck takes account of CAN messages and error telegrams re-
ceived.
During the scan time the CANcheck displays the bus load "online". In this way a
fluctuating bus load can be detected.
If you want to observe the bus load in your CAN network over a longer period,
you must change the scan time. This is done via the menu item "Settings".
At the end of the scan time the CANcheck provides a table with the bus load and
the error telegrams.
For the measurement of the bus load 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 measure the bus load.
Please select the menu item "Bus load" 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 bus load is measured and you can view the interim results
"online".
