Ethernet / LAN Network Protocol Typical Building Management System Architecture Internet WEB Browser Enterprise Server & Energy Analytics Station ENTERPRISE SERVER: An ENTERPRISE SERVER is defined as the Graphical User Interface (GUI) Software on a PC or a Server that provides the single point of access to the system via the MASTER CONTROLLERS. Graphics, Dashboards, Schedules, Setpoints, Analytics, Alarms, Trends, and Historical Data are accessed via the ENTERPRISE SERVER. MASTER CONTROLLERS: A MASTER CONTROLLER is defined as a microprocessor-based device that usually includes an Ethernet Port (to connect to an end user’s LAN/WAN) and one or more Field Bus ports (to connect to Field Controllers via an “Open Protocol” like LON, BACnet MS/TP, MODBUS, or via proprietary protocols).  The MASTER CONTROLLER usually provides scheduling, alarming, point trends/historical data, point sharing between field controllers (like Outside Air Temperature), and handles communication between controllers. Since MASTER CONTROLLERS are microprocessor-based, they require a programming tool. FIELD CONTROLLERS.FIELD CONTROLLERS are defined as microprocessor-based controllers that communicate to the MASTER CONTROLLER via an “Open Protocol” (i.e. LON, BACnet MS/TP or MODBUS) or via a proprietary protocol.  FIELD CONTROLLERS are the devices that actually control mechanical equipment such as AHU’s, RTU’s, VAV Boxes, Heat Pumps, Boilers, Chillers, etc.  Since FIELD CONTROLLERS are microprocessor-based, they require a programming tool, just as MASTER CONTROLLERS require a programming tool.

4. Why are Open Protocols & Open Systems Important? • End Users want the ability to change a Business Relationship • End Users are more cost-conscious than ever, thus they want choices. • End Users DO NOT want to be locked into one, and only one, Service Provider. • No choice in a Building Temperature Controls Service Provider results in escalated non-competitive service costs • No choice in a Building Temperature Controls Contractor results in escalated non-competitive addition or renovation costs • No choice in Building Temperature Controls Products results in escalated non-competitive repair costs • An Open System addresses all of these concerns

5. What is the Difference Between Open Protocols & Open Systems?

6. Open Protocols • An “Open Protocol”, as described by ASHRAE, provides a means by which computerized equipment may exchange information, regardless of the particular building service it performs, with other computerized equipment. As a result, an “open protocol” may be used by mobile and cloud-hosted devices, head-end computers, general-purpose direct digital controllers, and application-specific or unitary controllers with equal effect. • Common “Open Protocols” include: • LON & LON IP • BACnet MS/TP & BACnet IP • MODBUS RTU & MODBUS TCP

7. Open Protocols – A Brief Description of LON • LonTalk is the communication protocol used by LonWorks products as established by the LonMark Association. • Along with the LonTalk protocol, a LonMark profile is important because it signifies that a LonMark-identified device adheres to the interoperability guidelines set forth by the LonMark Association for a given application. The LonMark profile identifies mandatory and optional network variables for a given application that every manufacturer must include to ensure interoperability. • The LonMark approval provides a level of confidence that LON devices will communicate and interact properly.

8. Open Protocols – A Brief Description of BACnet • BACnet is the communication protocol developed by ASHRAE to promote “Interoperability”. • BACnet provides a model for creating an interoperable building automation system. • BACnet defines rules for: • LANs and Data Transport Systems • Objects that represent data and control functions • Services or data exchange methods • BTL (BACnet Testing Laboratories) Mark provides a level of confidence that BACnet devices will communicate and interact properly.

9. Open Protocols • Today, almost all Building Management System Manufacturers sell FIELD CONTROLLERS and MASTER CONTROLLERS that communicate via “Open Protocols”. • Mistakenly, many people within the Building Management System industry will define an “Open System” as a system that communicates via these “Open Protocols”. • Let’s be clear … Open Protocol ≠ Open System

10. Open Systems • An “Open System” is not defined by ASHRAE, so let’s define an “Open System”. • We define an “Open System” as a Building Management System utilizing an Open Protocol whose Products, Software, and Programming Tools and can be purchased, provided, and serviced by multiple qualified Contractors in a market. • A Building Management System whose Products, Software, and Programming Tools can be purchased, provided, and serviced by ONLY ONE QUALIFIED CONTRACTOR in a market is NOT an Open System – regardless of system Protocol.

15. How can I Learn More? • ASHRAE Technical Committee 7.5 is concerned with the performance and interactions of smart building systems (SBS), the impact of smart building systems on the total building performance, methods for achieving more intelligent control and operation of building processes, including supervisory control strategies and the optimization of dynamic building components and systems, interactions of smart buildings with utilities, and documentation of the benefits of smart buildings and smart building systems as they relate to energy consumption, cost of operation, maintenance, occupant comfort, building commissioning, operations, and impact of the SBS on utilities and natural resources. • https://tc0705.ashraetcs.org/
