1. General Information

1.1 BACnet/IP
BACnet is a communications protocol for building automation and control networks. It is an ASHRAE, ANSI, and ISO standard protocol. BACnet was designed to allow communication of building automation and control systems for applications such as heating, ventilating, and air-conditioning control, lighting control, access control, and fire detection systems and their associated equipment. The protocol provides mechanisms for computerized building automation devices to exchange information, regardless of the particular building service they perform.
BACnet/IP is based on Ethernet and used UDP to transmit BACnet network packets (NPDU). Messages are transmitted such as Who-is and Who-has through broadcast feature of UDP. The feature allows that the user could search for device information without knowing the actual location of the device.
1.2 Modbus

Modbus protocol mainly has two versions RTU and TCP. RTU can be realized through COM interface and TCP can be realized through Ethernet. These two protocols are commonly used in industrial control and automation industry.
Modbus RTU is used to transmit and exchange data via RS-232 or RS-485. It's a serial communication between master and slave. Every slave has a unique address to identify. Users could implement communication through using different function codes.
MODBUS TCP is a variant of MODBUS RTU. MODBUS messages are passed in an "Intranet" or "Internet" environment by using the TCP/IP protocol. The most common use of this protocol is to connect PLCs and gateways to other simple fieldbus or I/O networks via Ethernet.
