The Beckhoff CX1500-M200 is a Lightbus master fieldbus module, designed to extend the communication capabilities of Beckhoff Embedded PCs with a high-performance, fibre-optic-based fieldbus connection. As part of the CX1500 series of expansion modules, it provides a reliable and fast fieldbus interface, allowing embedded controllers to integrate seamlessly with Lightbus-based I/O systems in demanding automation environments.

The CX1500-M200 supports data transfer rates of 2.5 Mbaud, ensuring high-speed communication between the master and connected nodes. With the ability to handle 32 bits of process data in just 25 microseconds, it offers deterministic and real-time data exchange, making it particularly suitable for time-critical automation tasks such as motion control, robotics, and high-speed machinery synchronisation.

One of the strengths of the CX1500-M200 is its impressive scalability. The module can manage communication with up to 254 connected nodes, allowing for large and complex automation networks. With support for up to 65,280 individual I/O points, it is well-equipped to handle extensive distributed I/O systems while maintaining efficient and reliable communication. This scalability makes it a future-ready solution for both small and large industrial applications.

The device connects to the Lightbus network through two fibre-optic interfaces, which provide secure, interference-free data transmission over long distances. Fibre optics also ensure immunity to electromagnetic interference (EMI), making the CX1500-M200 ideal for harsh industrial environments where electrical noise could compromise traditional wired communication systems.

Integration with the CPU is achieved via an ISA plug-and-play interface with 2 kbytes of dual-port RAM (DPRAM). This ensures fast and efficient data exchange between the Lightbus module and the embedded controller, reducing communication delays and optimising system performance. The design is fully compatible with Beckhoff’s automation ecosystem, and when combined with TwinCAT software, the CX1500-M200 enables a unified control solution that incorporates PLC, motion, and fieldbus communication within a single platform.

Compact and efficient, the module has a footprint of only 38 mm x 100 mm x 91 mm. This slim design allows it to fit neatly into control cabinets alongside other CX system components. With a power loss of only 2 W, it operates efficiently without contributing significant thermal load, further supporting reliable and long-term operation.

In summary, the Beckhoff CX1500-M200 Lightbus master module is a powerful and reliable solution for integrating Embedded PCs into Lightbus networks. With its high-speed data rates, fibre-optic communication, and ability to manage large numbers of devices and I/O points, it provides engineers with a scalable and future-proof communication platform. Built for demanding industrial environments, the CX1500-M200 ensures robust and deterministic data exchange for advanced automation applications.
