BACnet is a communication protocol for building automation and control (BAC) networks that use the ASHRAE, ANSI, and ISO 16484-5 standards [1] 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 ...
When direct digital controllers are networked together they can share information through a data bus. The control system may speak 'proprietary' or 'open protocol' language to communicate on the data bus. Examples of open protocol language are Building Automation Control Network (BACnet), LonWorks (Echelon), Modbus TCP and KNX.
OpenADR – Open Automated Demand Response; protocol to manage electricity consuming/controlling devices; Optomux – Serial (RS-422/485) network protocol originally developed by Opto 22 in 1982. The protocol was openly documented [1] and over time used for industrial automation applications. PieP – An Open Fieldbus Protocol
The OPC specification was based on the OLE, COM, and DCOM technologies developed by Microsoft Corporation for the Microsoft Windows operating system family. The specification defined a standard set of objects, interfaces e.g. IDL and methods for use in process control and manufacturing automation applications to facilitate interoperability.
For most of the systems mentioned, protocol stacks are available in the form of CODESYS libraries which can be loaded subsequently onto the supported devices. In addition, the platform provides optional support for application-specific communication protocols, such as BACnet or KNX for building automation.

The data link layer FDL (Field bus Data Link) services [15] and protocols [16] work with a hybrid access method that combines token passing with a master/slave method. In a PROFIBUS DP network, the controllers or process control systems are the masters and the sensors and actuators are the slaves.
Profinet implements the interfacing to peripherals. [1] [2] It defines the communication with field connected peripheral devices.Its basis is a cascading real-time concept. Profinet defines the entire data exchange between controllers (called "IO-Controllers") and the devices (called "IO-Devices"), as well as parameter setting and diagnosi
