What are the best practices for integrating BMS with DALI and KNX protocols?

由人工智能和领英社区提供技术支持

Building management systems (BMS) are essential for optimizing the energy efficiency, comfort, and security of modern buildings. However, integrating different devices and systems can be challenging, especially when it comes to lighting and shading automation. Two common protocols for controlling lighting and shading devices are DALI and KNX, which have different features, benefits, and limitations. In this article, you will learn what are the best practices for integrating BMS with DALI and KNX protocols, and how to avoid common pitfalls and errors.

1 What is DALI?

DALI stands for Digital Addressable Lighting Interface, and it is a protocol for dimming and switching individual or groups of lights. DALI uses a two-wire bus that connects up to 64 devices, each with a unique address. DALI devices can be ballasts, drivers, sensors, switches, or controllers, and they can communicate with each other and with a central BMS. DALI allows for flexible and dynamic lighting scenes, as well as feedback on the status and performance of the devices.

DALI is an excellent technology, that allows ease of design, flexible prescription, and extremely beneficial technology usage. The biggest advantage comes from the installation, commissioning, and later on the ability to see all luminaries as addresses (very easy to locate potential issues) it also allows the combination of different luminaries in different scenarios to achieve higher customer satisfaction.

2 What is KNX?

KNX is a protocol for building automation that can control not only lighting, but also heating, ventilation, air conditioning, security, blinds, and other systems. KNX uses a twisted pair cable, a power line, a radio frequency, or an IP network to connect up to 256 devices per line, each with a unique address. KNX devices can be actuators, sensors, switches, or controllers, and they can exchange data and commands with each other and with a central BMS. KNX allows for complex and integrated automation scenarios, as well as monitoring and reporting of the devices.

KNX is a bus system.KNX is a world-standard KNX brings building functions together. KNX offers flexibility, safety, comfort, and cost efficiency. It started at 1990 - Constitution of the EIBA (European Installation Bus Association) based in Brussels to define technical guidelines, certification and awarding of the EIB trademark, preparing of European and international standards (DIN VDE 0829 and EN 50090) and coordination of the EIBA-member activities. 1999 – The EIBA merged with two other European organizations: BatiBUS Club International (BCI) European Home Systems Association (EHSA) As a result of this merger, the name was changed to KNX Association. Since then, we have used it as a communication protocol and standard for BMS

3 How to integrate BMS with DALI?

One way to integrate BMS with DALI is to use a gateway device that translates the DALI commands and data into a protocol that the BMS can understand, such as BACnet, Modbus, or LonWorks. The gateway device can be a standalone unit or a part of a DALI controller. The gateway device can also provide additional functions, such as scheduling, scene setting, or emergency lighting. The advantage of using a gateway device is that it simplifies the wiring and configuration of the DALI system, and it enables the BMS to control and monitor the DALI devices. The disadvantage is that it may introduce latency or compatibility issues, depending on the quality and performance of the gateway device.

To integrate a Building Management System (BMS) with DALI lighting, you need a gateway or interface device that can translate the commands and data between the BMS and the DALI network. The gateway typically communicates with the BMS via standard protocols such as BACnet, Modbus, or LonWorks, while also supporting DALI commands for controlling individual lighting fixtures.

The standard way to do this is to use a Gateway, which allows professional installers to integrate in BMS (Building Management Systems), deploy DALI/KNX installations more cost and time effectively thanks to the features combination. Configuration and commissioning is straightforward and fast thanks to embedded Application simplifying the process in the gateways. The architecture can be simpler because it is no longer necessary to use additional IP routers and KNX power supplies concerning given parameters. The typical gateway is designed for commercial installations and certified by BTL as a specific Controller (B-ASC) which ensures 100% compatibility, and at the same time, guarantees a seamless integration with any BACnet device

4 How to integrate BMS with KNX?

One way to integrate BMS with KNX is to use a router device that connects the KNX network to an IP network that the BMS can access. The router device can be a standalone unit or a part of a KNX controller. The router device can also provide additional functions, such as filtering, security, or diagnostics. The advantage of using a router device is that it allows the BMS to communicate with the KNX devices using standard IP protocols, such as TCP/IP or UDP/IP. The disadvantage is that it may require additional hardware and software components, such as switches, firewalls, or servers, depending on the size and complexity of the IP network.

Integrating a BMS with KNX involves connecting the KNX devices to the BMS through a gateway or interface module. Similar to DALI integration, the gateway translates communication between the BMS and KNX devices, allowing for centralized control and monitoring of building automation functions within the KNX network.

The usage of KNX BMS IP Gateway is a must. Verry often this is a bidirectional multifunctional device that allows you integrate KNX installations within most of the modern BMS systems (which are using open protocols over RTU/TCP communication). The main communication interface is KNX TP and BACnet IP protocols. Very often the gateteways for this purpose combine more than one function, such as: KNX IP router KNX IP interface DPSU choke power supply

5 What are the best practices for integrating BMS with DALI and KNX?

Careful planning and design are key when integrating BMS with DALI and KNX. Ensure that you select high-quality and compatible devices from reputable and certified manufacturers and suppliers, then follow their installation and configuration instructions. Testing and commissioning the system is essential to verify the functionality, communication, data exchange, integration, and interoperability with the BMS. Additionally, maintain and update the system regularly to monitor the status, performance, network traffic, bandwidth, security, and reliability of the system.

The best practices include a deep understanding of the architecture of the system. First of all, the DALI/KNX topology and its limitations. Secondly, the architecture of the BMS and its specificalities. As an example, a best practice is to design, commissioning and start using DALI as a standalone system (to prove that it works if BMS somehow loses communication with DALI) and then to integrate it via IP Gateways to the higher hierarchical levels.
