Filtering the CAN Traffic at Recording
When recording a trace file, all CAN traffic is processed. However, it
is possible to filter the incoming CAN messages.
A text file with a list of the CAN IDs to be filtered is created for this
purpose. The listed IDs pass through the filter. All others do not.
The filter file is placed on the memory card and loaded via the
device settings of the PCAN-MiniDisplay.
Do the following to apply a CAN ID filter:
1.
Create a filter file with the extension
*.flt
with a text
editor. The format of the file is described in the appendix
section D.3 on page 79.
2.
List the CAN IDs that can pass the filter.
3.
Connect the PCAN-MiniDisplay to the PC with the provided
USB cable. The PCAN-MiniDisplay does not need to be
powered on.
4.
Copy the filter file to the memory card in the
/
MiniDisplay/Filters/
directory.
5.
On the PCAN-MiniDisplay, navigate to
Device Settings
.
Select

Filter
for CAN channel 1 and
Ch.2

6.
Select the previously created filter file (

).
