CAN Bus Data Loggers
Introduction
CAN Bus Data Loggers are devices used to record and monitor data on a Controller Area Network (CAN) bus system. They enable nonproprietary data sharing between electronic control units (ECUs) in vehicles, machines, and other systems.
Key Features
- Compact size for easy vehicle integration
- SD card storage for large data sets
- CAN FD support for high-speed logging
- Advanced filtering to target specific CAN IDs
- Triggers to start/stop logging based on events
- Standalone operation without a PC
- Rugged enclosure to withstand harsh conditions
Additional Capabilities
CAN bus data loggers from CSS Electronics like the CANedge series offer additional capabilities like WiFi/cellular connectivity, over-the-air updates, and cloud integration. They can log data from multiple CAN and LIN buses in parallel with lossless capture even at full bus load.
Common Applications
CAN bus data loggers are widely used for vehicle telematics, ECU prototyping, and troubleshooting intermittent electrical issues. They provide a comprehensive vehicle black box to optimize warranty claims, document emissions, and analyze real-world performance.
