Building management systems often mix legacy field devices with modern analytics platforms. BACnet and Modbus remain the two most common protocols engineers evaluate first.
Modbus is straightforward for point-to-point device communication — ideal for meters, drives, and controllers where register maps are well defined. BACnet is designed for semantic building automation: objects, services, and networks that scale across campuses.
Auvetra integrates both protocols into a unified operational layer through Industrial Connectivity and Smart Infrastructure Integration — so facilities teams gain real-time visibility without replacing proven controllers. The right choice depends on device capabilities, vendor ecosystems, and whether you need standardized object models across sites.
