Siemens Desigo PX Driver for Tridium Niagara

The Desigo PX driver for Tridium Niagara is purpose-built to enable direct communication with Siemens Desigo PX controllers, allowing seamless integration into Niagara-based automation systems. For integrations involving the full Desigo CC management suite, please see the Desigo CC driver.

This driver offers a practical, engineering-friendly solution for retrofit projects, particularly where older Desigo PX controllers are in place and a Niagara front-end is desired. It supports efficient modernization by preserving existing field-level infrastructure while unlocking the visualization, control, and analytics capabilities of the Niagara platform. The result is a unified, future-ready automation layer that reduces operational silos.

Communication is established using BACnet over LonTalk protocol, that transports BACnet messages across the LonWorks FTT-10 physical layer. This hybrid approach leverages the robustness of LonTalk while exposing standard BACnet object models. Each object is self-describing, including attributes such as name, status, present value, and engineering units, which significantly simplifies mapping and point binding within Niagara.

The driver supports controller discovery across the Lon network and enables automatic import of points, schedules, and alarm objects. During discovery, metadata including labels, alarm states, and units are preserved, providing a plug-and-play experience that dramatically reduces setup time and ensures consistency across systems. With schedule objects accessible directly from PX controllers, time-based automation can be integrated into Niagara without additional configuration.

Engineers benefit from the driver’s streamlined workflow: fewer manual steps, reduced likelihood of errors, and quicker project delivery. Facility operators gain centralized access to real-time data, alarms, and scheduling—extending the value of both Desigo PX and Niagara investments. Whether in legacy buildings, campus-wide systems, or hybrid environments, the Desigo PX driver provides a clean path forward to scalable and interoperable automation.
