Trace Configuration for multiple files

Hello,
is it possible with PCAN Explorer 5 to generate multiple trace files in a row when the trace gets larger than a specified size?
In the PCAN-Parameter Documentation I've seen the "PCAN_TRACE_CONFIGURE" parameter with the value "TRACE_FILE_SEGMENTED" can I make use of this feature from within PCAN-Explorer or do I have to write my own application to store a segmented Trace file?
Thanks,
Markus

Hello,
I think you mixed up PCANBasic API parameters with PCAN-Explorer 5 commands. To build segmented PCAN-Trace files with PCAN-Explorer 5 you can use a VBmacro. You will find a sample macro called LossLessTrace in the PCAN-Explorer 5 macro list, which will do a segmented trace. You can also modify it to your needs.

Hi Michael,
thanks for the quick reply. I thought I could configure a tracer directly with API parameters but the macro also fits my needs
Regards,
Markus

Hello,
an additional question on the LossLessTrace: Is it possible to get continuous timestamps for the segmented traces?

Hello,
no, that is not possible. The timestamps are offsets related to the start of an individual trace file.

When parsing the trace file with a custom script later on, which starttime in the trace file's header should I take as reference?
While I do understand the human readable version in line 5, I don't get the meaning of $STARTTIME. I suppose it's some kine of "Seconds since..." but it does not seem to be consistent with the time from line 5 when comparing two tracefiles.
Code: Select all
;$FILEVERSION=1.3
;$STARTTIME=42199.6165978297
;
; d:\temp\Trace3.trc
; Start time: 14.07.2015 14:47:54.052.4
; Generated by PCAN-Explorer v5.3.4

Hi,
here the details from the PEAK Trace format specification about the STARTTIME, which is the Windows Time format:
$STARTTIME keyword to store the absolute start time of the trace file:
Format: Floating point, Point as decimal separator.
Value: Integral part = Number of days that have passed since 12/30/1899.
Fractional Part = Fraction of a 24 hour day that has elapsed, resolution is 1 Millisecond.
With each trace file, you will have a new STARTTIME value, the timestamps of the CAN messages will than be the offset from that STARTTIME value.
regards
Michael
