How to monitor CAN communications at a message level

Posted in in Automotive, CAN interfacing

Test development engineers working in vehicle control systems need convenient and compact communications devices to interface with single or multiple CAN networks.

These devices must have fully certified drivers covering a wide range of control software and many programming languages, such as C#, C++, VB.NET, MATLAB and others.

COMMDongle Pro and LiteIncreasingly, CAN isolation is needed to protect test hardware from failure and High Speed CAN protocols such as 2.0a and 2.0b need to be interfaced with – all using a compact, robust, plug-and-play device.

The COMMDongle range meets these needs.

COMMDongle units are shipped with CANSurf, which is our own diagnostics tool that runs in parallel with the device to monitor CAN messages.

CANSurf allows users to monitor, receive, send and log CAN messages on the CAN bus. Advanced features include message filtering, tracking and exporting to CSV, as well as broadcasting messages with time stamps.

It also comes with a 30-day trial of VISUALCONNX, our real-time systems interface creation software. VISUALCONNX allows complex interface creation, without the need for programming.

Utilising its direct interfaces to CAN database files, multiple buses can be interfaced with and signals are easily extracted and displayed. In addition, signals can be generated for node simulation as part of a manual or automated testing process.
