Next-gen industrial efficiency: Cervoz CAN Bus expansion solutions

This setup is ideal for manufacturing and automation, where consistent multi-node communication is crucial. Cervoz’s M.2 PCIe CAN Bus Expansion Cards offer tailored solutions for these high-demand environments. 

What is CAN Bus?

CAN Bus operates as a serial communication protocol that allows multiple devices, or “nodes,” to communicate in real time over a shared data line. Unlike conventional point-to-point wiring systems, CAN Bus utilises a multi-master structure, meaning each node can send and receive data independently, optimising communication efficiency and preventing data collisions. It employs differential signalling (CAN High and CAN Low) to enhance noise immunity, making it ideal for electrically challenging environments. Additionally, CAN Bus is designed with built-in error detection mechanisms, such as cyclic redundancy checks (CRC), which ensure reliable communication by identifying and correcting errors in transmitted messages.

Streamlining industries with CAN Bus connectivity

CAN Bus technology is proving indispensable in various industrial sectors, from automotive manufacturing and robotics to medical devices and beyond. Known for its ability to synchronise complex systems, CAN Bus enables machinery to respond dynamically to changing conditions, creating cohesive systems in real-time settings, such as assembly lines. In these setups, CAN Bus connects robotic arms, conveyor belts, and quality-control sensors, ensuring seamless communication across devices. The technology is increasingly adopted in industries like renewable energy and smart grids, where it supports rapid data collection and response, enhancing system performance.

Key Benefits of CAN Bus in Industrial Settings

Reliability in harsh environments: high noise resistance ensures consistent data flow and minimises errors in electrically noisy settings.

Scalability and flexibility: CAN Bus allows for the addition of multiple devices without significant rewiring. Depending on bus length and data rate, it can support up to around 110 nodes, making it highly adaptable to expanding industrial networks.

Real-time data transmission: with high-speed communication capabilities and priority-based message arbitration, CAN Bus supports the real-time exchange crucial for systems requiring immediate responses.

Cost efficiency: by reducing the need for extensive wiring and centralised control, CAN Bus minimises installation and maintenance costs, making it a cost-effective solution.
