The protocol of Digital Addressable Lighting Interface (DALI) was established in the early 1990s by a conglomerate of lighting product manufacturers to replace the original 0-10 V lighting control systems. It was designed as an open standard substitute to Digital Signal Interface (DSI), on which its structure is based [1]. The scope of this project was to control the lighting in the Murdoch University, South Street Campus, Western Australia by using a chosen controller to connect those modules to the chosen Schneider Enterprise/Automation server in the most efficient manner. This control would effectively allow Murdoch University to save more money on power, diminishing the impact on the environment due to power usage. This also gives a better suited environment to staff and students where lighting levels can be set at optimum levels defined by The Commission for Occupational Safety and Health [2] to reduce fatigue and glare. To achieve this control a microcontroller was used to sit as an intermediate path between the DALI devices and the Schneider BMS (Building Management System) that runs and monitors Murdoch’s South Street Campus by using Modbus.

Research was carried out in multiple fields (specifically cost, reliability, features and complexity) to investigate how other similar technologies accomplished this solution, and an ongoing study of the field of interest allowed for a more in-depth review of the current technologies advantages and drawbacks. The research was then used to verify the design work needed for the system and create the basics of the system, upon implementation of all designs and features, control of Murdoch University’s Library was achieved.
