The software enables both control of street lighting systems and capture of specific data on the basis of a Lonmark OLC luminaire controller as well as an intelligent Data Concentrator (iDC). This makes it easy to query and display technical data such as current, voltage, cos (phi), output, energy consumption, lighting hours as well as status updates regarding individual components and the entire lighting system. The tree-like structure of the system permits the display and visualisation of large data volumes in a structured manner, broken down by city, suburb and street.
