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 ...
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
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.
Distributed Network Protocol 3 (DNP3) is a set of communications protocols used between components in process automation systems. Its main use is in utilities such as electric and water companies. Usage in other industries is not common. It was developed for communications between various types of data acquisition and control equipment.

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
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.
The Security Content Automation Protocol (SCAP), pronounced "ess-cap", [2] but most commonly as "skap" comprises a number of open standards that are widely used to enumerate software flaws and configuration issues related to security. Applications which conduct security monitoring use the standards when measuring systems to find vulnerabilities ...
