The Niagara Framework (Tridium / Honeywell) is a multi-protocol software platform widely used in modern tertiary BMS, natively integrating BACnet (IP, MS/TP, SC), Modbus, KNX, OPC UA and others.
True
Niagara Framework is an integration ecosystem for BMS, structured around the JACE controller hardware (Java Application Control Engine), the Workbench Java engineering tool, a portfolio of drivers (BACnet, Modbus, KNX, OPC UA, MQTT, OEM), a semantic data model based on Project Haystack tagging and a configurable web HMI for visualisation. It is heavily used in the United States (Honeywell) and increasingly in Europe alongside Schneider EcoStruxure and Siemens Desigo CC. Familiarity with Niagara is a baseline skill for medium-to-large tertiary B2B projects.
When inheriting a Niagara station, export the BACnet Network and the Schedules to a readable file before changing anything: the platform's flexibility makes silent regressions easy to introduce.
