The N4 Supervisor is an IoT (Internet of Things) software platform used in server-class applications. It makes managing all buildings at an enterprise level possible, giving facilities managers the ability to quickly respond to problems and insights to optimize their buildings. Supervisor allows multiple Niagara-based JACE® controllers, along with other IP-based controllers, to be networked together. It serves real-time graphical information to standard web-browser clients and provides server-level functions. These functions include centralized data logging/ trending, archiving to external databases, alarming, dash boarding, system navigation, master scheduling, database management, and integration. It provides a comprehensive graphical engineering toolset for application development.
