Webinar: Demystifying CAN Higher Layer Protocols – J1939, CANopen, and UDS

If you work with embedded systems, off-road vehicles, industrial equipment, or any application running over a CAN bus, you've likely asked: how do I interpret what’s actually being sent over the wire? The answer lies in higher-layer protocols. This webinar breaks down the most widely used ones: J1939, CANopen, and UDS.

Presented by Torsten Gedenk of Emotas Embedded Communication GmbH, and hosted by Grid Connect, this session is a must-watch for systems integrators, controls engineers, and embedded developers who want a clearer picture of how these protocols function, overlap, and can even coexist on the same CAN bus.

You’ll walk away with a solid understanding of what each protocol offers, where it fits, and how to choose or support multiple layers in a single system. Plus practical insights you can apply immediately.

What You'll Learn

• Why CAN by itself isn’t enough and what higher-layer protocols add

• Key differences between J1939, CANopen, and UDS

• How messages are structured and interpreted by each protocol

• Address claiming, parameter grouping, and message timing in J1939

• CANopen’s object dictionary, PDOs, and SDOs

• How UDS uses ISO-TP to support large diagnostics messages

• Common challenges in mixing protocols on the same bus - and how to manage them

• Recommended tools and training resources to accelerate your development

Who Should Register

This webinar is ideal for:

• Embedded and controls engineers working in transportation, automation, industrial, or medical applications

• Developers supporting ECUs, gateways, or diagnostics over CAN

• Anyone seeking to mix or troubleshoot multiple CAN-based protocols in one network
