There are numerous efforts to take Ethernet to the edge devices but network fragmentation has resulted in multiple communication networks coexisting in building automation – heating, ventilation and air-conditioning (HVAC) applications use Modbus, access control uses BACnet, lighting uses LonWorks and fire safety uses Ethernet. Single Pair Ethernet offers a simplified solution that could support all these devices and offer direct accessibility for the control system, status updates, predictive maintenance, standardized hardware and interoperability across various systems.
