HLI is an acronym for High Level Interface, this is a device which is installed by the O.E.M (original equipment Manufacture) in to an item equipment which allows monitoring and control of said equipment directly via the BMS communications network. For example, a chiller or a generator. The item has a BACnet or Lon work HLI installed. the device when connected and configured into the network appears on the network like a typical controller. Via programming or “mapping” the parameters of the HLI can be introduced into the BMS programming directly. A HLI is incredibly efficient as it uses data, the HLI allows alarms and programming to be configured directly by as an O.E.M device in the network, it provide real time monitoring and control parameters.
