Which protocol runs over Ethernet and is commonly used for device interconnection within a building automation system?

In building automation, using a protocol that travels over Ethernet lets many devices talk on a common network without serial adapters. Modbus TCP is the version of Modbus designed to run directly over TCP/IP on Ethernet networks. It communicates Modbus frames using standard Ethernet infrastructure, often on port 502, making it a natural choice for interconnecting controllers, sensors, and actuators across a building.

The other options don’t run over Ethernet by default: Modbus RTU is the serial version (RS-485/RS-232), BACnet MSTP uses RS-485/RS-422, and LonWorks uses its own media and transport layers. So Modbus TCP is the Ethernet-based protocol commonly used for device interconnection in a building automation system.
