Overview; Bacnet Protocol - Trane BACnet BCI-R Integration Manual

Overview

The BACnet Communication Interface for ReliaTel (BCI-R) supports Trane ReliaTel rooftop units that
function as part of a BACnet MS/TP communications network. It allows ReliaTel equipment to
communicate with a building automation system (BAS) by using the BACnet protocol over an
RS-485 MS/TP communications link.

BACnet Protocol

The Building Automation and Control Network (BACnet and ANSI/ASHRAE Standard 135-2004)
protocol is a standard that allows building automation systems or components from different
manufacturers to share information and control functions. BACnet provides building owners the
capability to connect various types of building control systems or subsystems together for a variety
of reasons. In addition, multiple vendors can use this protocol to share information for monitoring
and supervisory control between systems and devices in a multi-vendor interconnected system.
The BACnet protocol identifies standard objects (data points) called BACnet objects. Each object
has a defined list of properties that provide information about that object. BACnet also defines a
number of standard application services that are used to access data and manipulate these objects
and provides a client/server communication between devices. For more information on BACnet
protocol, refer to
BACnet Testing Laboratory (BTL) Certification
The BCI-R supports the BACnet communication protocol and has been designed to meet the
requirements of the application-specific control profile. For more details, refer to the BTL web site
at www.bacnetassociation.org.
