To whom it may concern,

I'm about to do some DV test for our product, and i wanna log the CAN messages for reference,I may use "trace record" and "Line writer record" function to log the output CAN messages.

So my question is does P-CAN Expoler5 have storage limt for "trace record" and "Line writer record" function? like how long or how much data it can store continuously? Cause my test may last weeks or month. btw i only have less than 10 signals to trace.

I am looking forward to your early reply,

Thanks,

Hi,

yes, due to the fact that PCAN-Explorer is a 32bit application, it can only allocate around 2GB memory on the system. So typically there will be problems when the application needs more than 1.5GB. But we deliver a VBmacro which is called LossLessTrace, which will cut the trace files into defined sizes, so that you can log the CAN traffic as long as you have space on your harddisk.
You can also set a filter, to reduce the needed space in your trace files.

Hi Michael,

Thanks for your answer, I just found VBmacro i'll try it, but how about"Line writer record" ? it stored in the format of .plw file. Does it have storage limit? and here is one thing that when i opened it in Excel the characters are all messed up. what it might be?

Hi,

the storage limit for the line writer file is the same as for the trace. If you use trace and linewriter at the same time, it will reduce the storage limit by half.

The linewriter .plw file is a binary file which could not be used in Excel. If you want to use Excel, please use the CSV export option for the trace files.

The optional available Plotter Add-in can also import traces and store the data in a Excel usable format (*.plt).
