BACnet Training

Lesson 1 • History and Purpose of BACnet

Traces BACnet's origin as an open standard for building automation interoperability. Provides context for why BACnet replaced proprietary protocols in HVAC and facility systems.

Lesson 2 • Standards and Compliance Framework

Explains the international standard structure governing BACnet and the testing regime for compliance. Enables practitioners to evaluate vendor claims and select compliant equipment.

Lesson 3 • Core Concepts and Terminology

Defines essential BACnet vocabulary including objects, properties, and services. Accurate terminology use is required for all subsequent protocol configuration work.

Lesson 1 • Device and Program Objects

Examines the Device object as the mandatory self-description container and Program objects for embedded logic. Understanding these objects is essential for device discovery and diagnostics.

Lesson 2 • Proprietary and Future Object Extensions

Explains how vendors extend the standard with proprietary object types and how future addenda add new types. Prepares students to handle non-standard objects without breaking interoperability.

Lesson 3 • Multi-State and Accumulator Objects

Introduces Multi-State Input, Output, Value, and Accumulator objects for discrete and pulse-count data. Extends the object model to cover equipment with enumerated states.

Lesson 4 • Analog and Binary Object Types

Covers Analog Input, Output, Value, Binary Input, Output, and Value objects and their mandatory properties. Forms the basis for reading sensor data and commanding field devices.

Lesson 1 • MS/TP Serial Network Operation

Explains the master-slave token-passing protocol used on RS-485 wiring for field-level devices. MS/TP remains the most common physical layer for controllers and sensors.

Lesson 2 • BACnet/IP Architecture and Configuration

Covers UDP/IP encapsulation, BBMD operation, and foreign device registration for routed networks. BACnet/IP is the dominant data link and the foundation for most modern deployments.

Lesson 3 • BACnet/SC Secure Connect

Introduces the WebSocket-based, certificate-authenticated data link added to address security gaps. Positions BACnet/SC as the emerging replacement for BACnet/IP in secure environments.

Lesson 1 • Confirmed vs. Unconfirmed Services

Distinguishes confirmed services requiring acknowledgment from unconfirmed fire-and-forget messages. Correct service selection affects reliability, bandwidth, and system responsiveness.

Lesson 2 • Alarm and Event Services

Details ConfirmedEventNotification, UnconfirmedEventNotification, and acknowledgment workflows. Alarm services are critical for life-safety and fault-management applications.

Lesson 3 • Subscription and COV Services

Covers SubscribeCOV and SubscribeCOVProperty for change-of-value push notifications. COV reduces polling overhead and improves real-time responsiveness in large systems.

Lesson 4 • Read and Write Property Services

Covers ReadProperty, ReadPropertyMultiple, WriteProperty, and WritePropertyMultiple as the core data-access services. These services underpin every supervisory read and command operation.

Lesson 1 • Designing a Site Priority Scheme

Guides students through creating a documented priority assignment policy for a complete facility. A consistent scheme prevents integration conflicts when multiple systems share one device.

Lesson 2 • Priority Array Structure and Levels

Explains the 16-slot priority array, relinquish default, and present value resolution. Understanding this structure is mandatory before writing any command to a BACnet output object.

Lesson 3 • Life-Safety and Manual Override Priorities

Covers reserved high-priority levels for life-safety and manual override applications. Misuse of these levels can create dangerous or unresolvable command conflicts.

Lesson 1 • Trend Log and Trend Log Multiple Objects

Covers Trend Log and Trend Log Multiple objects for time-stamped data collection. Trending is essential for energy analysis, fault detection, and regulatory reporting.

Lesson 2 • Notification Class Routing and Acknowledgment

Configures Notification Class objects to route alarms to the correct recipients with acknowledgment requirements. Proper routing ensures alarms reach operators without duplication or loss.

Lesson 3 • Schedule and Calendar Configuration

Builds complete Schedule objects with weekly routines, exception entries, and Calendar references. Automated scheduling reduces manual operator intervention and energy waste.

Lesson 1 • System Acceptance and Handover

Covers documentation, owner training, and formal acceptance criteria for a commissioned BACnet system. A structured handover protects both the integrator and the building owner.

Lesson 2 • Interoperability Testing and Verification

Defines procedures for verifying that devices from multiple vendors exchange data correctly. Interoperability testing is the final gate before system handover.

Lesson 3 • Commissioning Tools and Procedures

Introduces software tools for device discovery, object browsing, and service testing during commissioning. Systematic commissioning reduces integration errors and shortens project timelines.

Lesson 4 • Router and Gateway Configuration

Covers configuring BACnet routers to interconnect MS/TP, BACnet/IP, and other segments. Routers are the backbone of multi-segment BACnet installations.

Lesson 1 • Scalability and High-Availability Design

Covers redundant BBMD pairs, BACnet/SC hub failover, and database replication for mission-critical sites. High-availability design prevents single points of failure in life-safety systems.

Lesson 2 • Integration with SCADA and IoT Platforms

Explains how BACnet data is exposed to SCADA, cloud IoT, and analytics platforms via APIs and gateways. Integration expands BACnet's value beyond local control to enterprise decision-making.

Lesson 3 • BACnet Security and Access Control

Covers BACnet/SC certificate management, network key distribution, and access control lists. Security hardening is now a baseline requirement for connected building systems.

Lesson 4 • Fault Detection and Diagnostics

Applies BACnet trending, alarming, and COV data to automated fault detection and diagnostics workflows. FDD reduces energy waste and equipment downtime in complex facilities.
