Full Description

Meet Building Automation and ControlSystems Communication Needs with Standard 135-2020
This product is only available as aPDF.

BACnet, the ASHRAE buildingautomation and control networking protocol, has been designed specifically tomeet the communication needs of building automation and control systems forapplications such as heating, ventilating, and air-conditioning control; fireand other life safety and security systems; energy management; lightingcontrol; physical access control; and elevator monitoring systems. The BACnetprotocol provides mechanisms by which computerized equipment of arbitraryfunction may exchange information, regardless of the particular buildingservice it performs. As a result, the BACnet protocol may be used by mobile andcloud-hosted devices, head-end computers, general-purpose direct digitalcontrollers, and application-specific or unitary controllers with equal effect.

This protocol provides acomprehensive set of messages for conveying encoded building automation databetween devices:
* Hardware binary input and output values
* Hardware analog input and output values
* Software data values
* Schedule information
* Alarm and event information
* Trend and event logs
* Files
* Control logic
* Application specific data for a large range of building services
* Network configuration including security

The 2020 edition of Standard 135 includesmany new capabilities and several clarifications. New capabilities include lightingand elevator device profiles that provide a standardized description for thesetypes of devices, along with audit reporting and logging to capture auditableactions. BACnet Secure Connect, a BACnet datalink layer, was also added. Thisdatalink is fully compatible with all existing BACnet datalinks and provides aninteroperable secure path for BACnet communications.
