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 ...
BACnet – for Building Automation and Control networks, maintained by ASHRAE Committee SSPC 135. ... LonTalk – protocol for LonWorks technology by Echelon Corporation;
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.
There are many well established binary protocols (BACnet, LonTalk, Modbus, DALI) that are used on these dedicated networks in addition to numerous proprietary protocols. While these binary protocols can be used over TCP/IP networks - they have challenges with routers, firewalls, security, and compatibility with other network applications.
OpenADR will also need to interoperate directly or interwork indirectly with other popular protocols now used for energy management, including BACnet, LonMark [19] and the Smart Energy Profile ZigBee. Depending on the protocol, this is expected to be accomplished either with enhancements to these standards, or with separate software or systems ...
In 1999 the communications protocol (then known as LonTalk) was submitted to ANSI and accepted as a standard for control networking (ANSI/CEA-709.1-B), in 2005 as EN 14908 (European building automation standard). The protocol is also one of several data link/physical layers of the BACnet ASHRAE/ANSI standard for building automation.
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.
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. Its main use is in utilities such as electric and water companies.
