Most of these devices are low cost and not enabled for TCP/IP. They are installed with dedicated communications wiring. Larger DDC controllers provide network communications for these dedicated controllers. There are many well established binary protocols (<a href="/wiki/BACnet" title="BACnet">BACnet</a>, <a href="/wiki/LonTalk" title="LonTalk">LonTalk</a>, <a href="/wiki/Modbus" title="Modbus">Modbus</a>, <a href="/wiki/Digital_Addressable_Lighting_Interface" title="Digital Addressable Lighting Interface">DALI</a>) 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. There is an added challenge in that the industry is split between several largely incompatible protocols. </p><p>Because oBIX integrates with the enterprise, it enables mechanical and electrical control systems to provide continuous visibility of operational status and performance. By exposing these operations using web services, it enables owners and tenants to use the full array of standard databases and OLAP tools to analyse their performance. oBIX enables facilities operators, owners and tenants to make decisions based on a fully integrated consideration of all life-cycle, environmental, cost, and performance factors.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="reliable source needed for verifiability (February 2011)">citation needed</span></a></i>]</sup> </p> <div class="mw-heading mw-heading2"><h2 id="Scope">Scope</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=OBIX&action=edit&section=2" title="Edit section: Scope"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>oBIX provides a publicly available web services interface specification that can be used to obtain data in a simple and secure manner from HVAC, access control, utilities, and other building automation systems, and to provide data exchange between facility systems and enterprise applications. Release 1 provides a normalized representation for three of elements common to control systems: </p> <ul><li><b>Points</b>: representing a single scalar value and its status – typically these map to sensors, actuators, or configuration variables like a setpoint.</li> <li><b>Alarming</b>: modeling, routing, and acknowledgment of alarms. Alarms indicate a condition which requires notification of either a user or another application.</li> <li><b>Histories</b>: modeling and querying of time sampled point data. Typically edge devices collect a time stamped history of point values which can be fed into higher level applications for analysis.</li></ul> <p>oBIX 1.0 provides a low level object model which can be extended during implementation. While points are directly addressable (and thereby settable), direct interaction with the points requires too much knowledge of the underlying control system for the enterprise developer. The underlying points can be aggregated, the results named, alarm levels set, and histories begun using the oBIX <b>contract</b>. If oBIX exposes a low level object model for control systems, oBIX contracts create the higher level type libraries that most programmers actually want to work with. </p> <div class="mw-heading mw-heading2"><h2 id="Uses_of_oBIX">Uses of oBIX</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=OBIX&action=edit&section=3" title="Edit section: Uses of oBIX"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-heading mw-heading3"><h3 id="Tenant_interactions">Tenant interactions</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=OBIX&action=edit&section=4" title="Edit section: Tenant interactions"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>To keep a public space open in the evening may require a range of calls to different organizations within a building, each initiating an interaction with a separate building control system.

(1) An intelligent agent residing in the building, and negotiating with the building tenants and their business processes negotiates set building system operating postures. (2) An external agent hired by the building tenants aggregates demand across multiple buildings and buys power on their behalf. Markets based on these interactions are considered to be key to creating market conditions to drive rapid innovation in on-site power storage and generation technologies. </p> <div class="mw-heading
