Leveraging Single-Pair Ethernet In Building Automation

186
 

There are numerous efforts to take Ethernet to the edge devices. Multiple communication networks currently exist in building automation – for example, heating, ventilation and air-conditioning (HVAC) applications use Modbus, access control uses BACnet, lighting uses LonWorks and fire safety uses Ethernet. This fragmentation of networks requires the use of gateways to perform protocol conversion to unite merge networks at the top of the building automation control pyramid. End users must in turn manage complex systems.

Reasons for the existence of various communication networks include the need for longer distances, multidrop connectivity, powering scheme and support for unique protocols. Single-pair Ethernet (SPE) can address many of the above said reasons. Having Ethernet to the edge devices offers benefits such as direct accessibility for the control system, status updates, predictive maintenance, standardized hardware and interoperability across various systems.
