- The log file is compatible with Vector CANalyzer and CANoe.
- The log file is logged in hexadecimal.
- Timestamp contains 6 digits.
- The content in the log file has different formats for different types of CAN messages.
- The CAN message up to 8 bytes are logged. Any message larger than 8 bytes are discarded, e.g. for J1939 transport layer frames, the long frames displayed in CANtrace are not logged, only the multiple 8-bytes frames are logged. CANtrace will re-assemble and display the long frame when playing back the log file that contains the multiple frames.
