CANtrace – CAN bus Analyzer software
Product Code: CANtrace
A Powerful CAN BUS analyzer software – CANopen & J1939
CANtrace is an easy-to-use CAN network analyzer, that lets you trace, decode and plot CAN messages and signals in real-time, or log everything for post processing in the comfort of your office.
It works with your current Kvaser, Softing, Vector or Peak hardware and it supports both CANopen and J1939 protocols. CANtrace supports now also scripting.

View and Decode Any CAN Message
Data is transmitted on the CAN bus in 0-8 byte long messages, including a CAN ID and data length (DLC). And the message timestamp from your CAN interface, and that’s about all you get from a free CAN tool.
RAW CAN Data
But what does it mean?
Is it data, configuration or an alarm?
Most free CAN tools will display the raw data, but you have to decode every message manually, flipping through thick protocol manuals to find out what 0x40 really mean.
CANtrace Does the Decoding
With CANtrace you don’t have to decode the CAN data manually. The included CANopen and J1939 protocol parser will decode protocol headers, while the connected databases (DBC) will decode signal values.

Use Your Existing CAN Interface
With CANtrace you don’t have to invest in expensive CAN hardware to get started. If you are like most CANtrace customers, your engineers already use at least one CAN interface, and with CANtrace it’s possible to tie your CANtrace license to your existing hardware.
If you own a CAN interface from any of the following manufacturers, it will work with CANtrace. For Kvaser, Softing and Vector hardware, the license is tied to the hardware. For Peak hardware, the license is tied to the PC. CANtrace can be shared by several people as long as you use the same Kvaser, Softing or Vector CAN hardware.
- Kvaser AB (all models)
- Vector Informatik GmbH (all models)
- Peak System (all models)
- Softing AG (all models)
Users can use additional Python scripts inside the program to extend the default functionality of CANtrace. Scripts can be used to create, filter, and modify signals dynamically for different uses. Descriptive example projects are also included in the public CANtrace folder.
Human Readable Data (DBC Databases)
Many CAN messages contain several different data values, or signals, and it is a pain to manually decode the binary data.
But it doesn’t have to be that way! In CANtrace signals are decoded and displayed in human readable form. The real-world data from your CAN network can be monitored, logged and plotted using familiar engineering units. You will see the RPM and temperature in the same format you are used to.
Signals are decoded using your existing CAN database, in the commonly used DBC format. You can connect a separate database to every CAN interface (channel) and there is even a handy database editor included in CANtrace.
Plot Your Data in The XY Graph
- CANtrace contains a powerful graphical presentation of data where you can plot multiple signals in a xy graph.
- The graph supports multiple J1939 signals as well as signals from manufacturer specific DBC databases.
- The graph supports multiple data-cursor styles for each signal for you to take the measurements. e.g. X-Y, Y, Period, Peak-Peak and Frequency.
- The signals can be scaled and moved using simple mouse commands
- They can be scaled individually or as a group, and signals are color coded for clarity of display.
- The X-Y graphs can be printed to your standard windows printer with the click of a button
- The graph can be saved to a file when you need to include it in a report or on your website.
You can produce graphs from data you logged with any CAN logger, as long as it supports the popular Vector asc log format.
Logging and playback log file
CANtrace supports Vector ASCII format CAN log files. In addition to recording log data from multiple channels. CANtrace can also play back log files to the CAN bus. Any log file in ASC format can be used to generate data on the CAN bus. This feature can be very useful for simulation, testing and bus traffic generation.

Supports The J1939 Protocol
In the trace view, J1939 parameter groups (PG) are decoded to human readable format. In addition, CANtrace supports the J1939 transport layer protocol and can both send and receive suspect parameter embedded in transport layer segments. CANtrace comes with a J1939 database in DBC format. This allows natively decoding the standardized 8-byte J1939 messages that are specified in the SAE J1939 Digital Annex.
CANtrace also supports combining the included J1939 database with a customer-specific database. This enables the decoding of vehicle-specific parameters.
For J1939 format databases, CANtrace is able to mask out both priority, source address and destination address fields which allows the use of compact J1939 databases that works with a variety of different vehicles.
Ideal for Field Work
When you find that you need to take your CAN toolbox with you and go on a fault-finding mission outside your office or R&D department you will appreciate that CANtrace was designed from the ground up to be easy to use, and to display well, on a small laptop or handheld display as well as on your standard desktop monitor. Install CANtrace on your rugged tablet PC and you will have a CAN logger you can leave for hours or days in the engine compartment of the equipment you are diagnosing.
