Software / CAN bus
Keep an eye on the CAN bus
The software comes with the tools for the CAN bus: a bus overview for all traffic, a window for sending your own messages and a library of DBC files.

CAN bus
The bus overview
The bus overview shows all CAN traffic live in a table: timestamp, ID, bus, direction and data bytes. If a device has two CAN buses, they can be viewed separately or together, with bus load and messages per second.
It is a helpful tool when troubleshooting.
Send your own messages
In the send window you create your own CAN messages: once, at a fixed rate or as a reply to a received message. That lets you stand in for a missing control unit or test a device on the bench.
The data bytes can change on every send, for example count up or take a byte from a received message. Send lists are saved as files, in the same format as in the program SavvyCAN.
Choose a DBC file
A DBC file describes which signals are in a message. The software ships files for common engine control units.
With the bus connected the library listens and shows for each file the match with the running traffic in percent. That way you find the right file for a foreign control unit without taking its messages apart by hand.
Read signals from a message
What a device receives is defined by a CAN input in the logic editor. It takes the signals of a message straight from the DBC file or from your own start bit, length and scaling.
After that the signals can be selected on the whole control unit, on the display pages too.
Create a message
A CAN output in the logic editor creates a message of your own: ID, bus and send rate, plus one row per signal with start bit, length and scaling.
In the simulation the messages do not go onto the real bus but into the bus overview. You see what the graph would send.
Several signals in one message
A message usually carries several signals. The signal viewer shows them as a bit grid, each signal in its own colour. You see at a glance where a signal sits and which bits are still free.
Start bit, length, byte order, factor and offset are set here. A click on another signal of the message switches to it.
How it works
- ConnectPlug in an adapter or a device over USB.
- WatchThe bus overview shows what is on the bus.
- MatchPick the fitting DBC file from the library.
- UseUse the signals in the logic graph and on the display.
At a glance
- On devices with two CAN buses: view them separately or together
- Classic CAN with 11 and 29 bit IDs
- Connection directly through the USB of a Cronesix device or through an SLCAN adapter
- Send lists in the SavvyCAN format
- Your own DBC files are kept across updates
Trying it costs nothing
The software is free and runs without a connected device. Every device can be opened and viewed offline.
