Overview

SIST EN ISO 16484-5:2022 - part of the ISO 16484 series - defines the data communication protocol used in building automation and control systems (BACS). Its purpose is to specify data communication services and protocols for computer equipment that monitor and control HVAC&R and other building systems. The standard also provides an abstract, object‑oriented representation of the information exchanged between devices, enabling consistent digital control across heterogeneous building systems.

Keywords: Building automation and control systems, BACS, BACnet, data communication protocol, HVAC control, building management systems.

Key topics and technical requirements

BACnet protocol architecture: collapsed architecture, network topology and security considerations.

Application layer: APDU transmission, segmentation, application protocol state machines and service conventions.

Network layer: network-layer PDU structures, multi-recipient messaging, routing and router behavior.

Data link / Physical layers: mappings for multiple media including Ethernet (ISO 8802-3), ARCNET, MS/TP (Master-Slave/Token-Passing), Point-to-Point (PTP) and LonTalk (ISO/IEC 14908.1).

Device modeling: object-oriented models for control devices - object types such as Analog Input/Output/Value, Binary Input/Output/Value, Calendar, averaging and related object characteristics.

Implementation aids: message formats, CRCs, medium access control, COBS encoding for MS/TP, router and repeater behaviours, and documentation guidance for device design choices.

Standards harmonization: normative mappings to international LAN standards and guidance for national adoption (CEN endorsement).

Practical applications

Specifying and implementing BACnet-based building management systems (BMS/BMS) for HVAC, lighting, access control, and energy management.

Designing interoperable controllers, sensors, actuators and gateways that exchange object-based data across Ethernet, MS/TP or LonTalk networks.

Enabling system integrators and manufacturers to implement consistent APDU, network routing and data-link behaviours for reliable monitoring and control.

Supporting facility managers and consultants in procurement specifications that require BACnet compliance for interoperability and future-proofing.
