The Bachmann CM202 is a high-performance CAN fieldbus master module designed for industrial automation systems. It ensures reliable communication across multiple CAN networks while supporting both master and slave configurations. Engineers benefit from dual isolated CAN ports, comprehensive protocol support, and easy configuration through the SolutionCenter software.
Key Features
- Supports up to 4 CM202 modules per M1 controller for flexible system expansion.
- Handles 8 independent CAN networks per controller with individual mode selection.
- Compatible with CANopen, SAE J1939, NMEA2000, and custom protocols.
- Offers dual galvanically isolated CAN ports with short-circuit protection.
- Enables Node Guarding or Heartbeat monitoring for network reliability.
- Transfer rates range from 10 Kbaud to 1 Mbaud depending on cable and network configuration.
- Provides comprehensive API for SDO, LMT, LSS, and emergency messages.
- Supports variable cable length and network nodes depending on baud rate.
