CAN Bus Testing & Verification

Published on Sep 4, 2026

This CAN bus testing setup features a USB CAN analyzer connected to a PC running GCANTools. The analyzer communicates with industrial devices such as PLCs and servo drives through CAN_H and CAN_L connections. Engineers can configure CAN baud rates, transmit and receive CAN frames, verify message IDs and data bytes, and test communication responses between connected devices. This solution is suitable for CAN interface testing, device development, system integration, and industrial communication verification.

CAN Bus Testing & Verification

Application Description

This application is designed for testing and verifying basic CAN bus communication between industrial devices, controllers, and electronic modules.

How It Works

1 - Connect the USBCAN analyzer to a PC via USB.
2 - Connect its CAN interface to the target device or CAN network using CAN_H and CAN_L.
3 - Configure the CAN baud rate and frame parameters in GCANTools.
4 - Send CAN messages from the PC and monitor incoming messages from connected devices.
5 - Verify message IDs, data bytes, transmission intervals, and communication responses.

System Connection

Functions & Benefits
