LONWORKS通信系统广泛应用于建筑物自动化系统，用于照明，防晒，暖通空调，能源管理和安全应用中的住宅和非住宅控制的现场级和应用级功能。 BACnet通信系统也用于管理层和应用级功能的楼宇自动化系统。该技术规范定义了将BACnet网络与LONWORKS网络组合在一起的方法，并对BACnet和LONWORKS系统之间的接口进行了标准化

The LONWORKS communication system is widely used in building automation systems for field-level and application-level functions for residential and non-residential controls in lighting, sun protection, HVAC, energy management and security applications. The BACnet communication system as well is also used in building automation systems for management-level and application-level functions. This technical specification defines the methods for combining BACnet networks with LONWORKS networks, and standardizes the interface between BACnet and LONWORKS systems.
