Overview

The Bachmann CM202 is a high-performance CAN fieldbus master module engineered for robust communication in industrial control systems. It is part of Bachmann’s modular automation platform and is widely used in sectors such as energy, marine, and manufacturing. The module enables seamless integration of distributed devices using Controller Area Network (CAN) technology, which is known for its reliability and noise immunity.

Moreover, the CM202 supports two galvanically isolated CAN interfaces, allowing it to operate two completely independent CAN networks simultaneously. This dual-channel architecture enhances system flexibility and fault tolerance. In addition, the module supports multiple CAN-based protocols including CANopen, J1939, and NMEA 2000, which can be configured via Bachmann’s SolutionCenter software using EDS files or application-level programming.

Its rugged design ensures stable performance even in environments with high electrical interference, vibration, or temperature variation. Therefore, the CM202 is a trusted solution for engineers building scalable and resilient automation systems.
