Helixx™ Framework with Onyxx® MB311 Bridge: Advanced Modbus to BACnet Communication

The Onyxx® MB311 Bridge, embedded with Lynxspring’s Helixx™ framework, has redefined how Modbus to BACnet communication is managed in building automation. This cutting-edge integration not only translates up to 2,500 Modbus points into streamlined BACnet points, but also converts each Modbus slave into a virtual BACnet device using advanced virtual BACnet routing technology.

Virtual BACnet Device Emulation

For every Modbus slave device added, Helixx automatically creates a corresponding virtual BACnet device. These virtual devices emulate their Modbus counterparts while maintaining network integrity by assigning each one a unique BACnet device instance/object ID, ensuring clear identification across the BACnet network.

Seamless Modbus Point Mapping

With Helixx, desired Modbus points are easily added beneath the relevant Modbus slave device. The system then automatically maps and creates the appropriate virtual BACnet object for each point, eliminating the need for manual configuration or third-party software tools.

Onyxx® MB311 Capacity and Compatibility

• Supports up to 2,500 Modbus points

• Accommodates 32 Modbus RTU slave devices without a repeater, or up to 246 devices with repeaters

• Supports up to 246 Modbus TCP slave devices per network segment, or a combination of RTU and TCP

Thanks to the built-in Helixx interface, all setup and configuration can be completed via a standard web browser, with no need for additional software. The interface includes configuration tools, help guides, documentation, and device settings to ensure a smooth project deployment.
