Files and device descriptions

A communication recording stores observed data; a device description helps interpret it. Choose a format for your task and keep related files together when sharing.

File	Purpose	Considerations
.ptrc	Raw CAN-frame recording	Application decoding depends on the module and available descriptions
.ptrbs	Modbus RTU byte-stream recording	The main file may require adjacent .sNNN.ptrbs segments
CAN Hacker .trc	Import an existing CAN trace	Other formats with the same extension are not necessarily compatible
.meta	User trace labels	Share it alongside the main recording
.log	Text export of source records	Does not replace a binary trace for reopening
EDS/DCF	CANopen object and configuration descriptions	Does not replace a recording; share any description used separately

See trace files for saving, loading, exporting, and hardware ISO-TP limitations. CANopen interpretation is covered on the module page.

For issue reports, distinguish an exported communication log from the application's technical log.
