This course explores the principles of the KNX protocol and includes both theoretical learning and hands-on exercises to build your understanding of the KNX system configuration tool, ETS.
KNX has existed for over 30 years as the leading standard for home and building automation. This module explores the structure and roles of the KNX association and the different ways the KNX standard is implemented as system solutions. It also covers the unique value proposition that is KNX with a detailed look at the sales arguments.
You will learn to:
This module introduces the minimum requirements to form a KNX installation and how they are addressed. It then looks at how group addressing is used for run time communication alongside the function of datapoints to guarantee device interoperability. The structure of telegrams is briefly explained before a more in-depth look at how bus communication works including the role of chokes which are integrated in KNX power supplies. Finally the distance and device limits on a single line are covered along with the reasons why these are needed.
You will learn:
In this module we will cover the physical parts of the KNX installation starting with an explanation of SELV, the KNX cable and the requirements when installing. After a quick look at DIN rail cabinets, the use of KNX power supplies is covered in depth including the standard features, the use of auxiliary connections, and distributed power supplies. The physical connections to the bus and the benefits of having a standard removable push connector are covered followed by a look at lighting & overvoltage protection for the system, as well as running cables between buildings. Finally the testing methods for a KNX installation are detailed.
The KNX system can have over 60,000 devices. This module looks into the way this is managed using lines, areas, and backbone areas. Line couplers are introduced, explaining how they perform to manage the traffic flow through the system. Finally the use of KNX IP lines is covered including their role in larger systems and how to ensure the bus integrity is protected.
This module looks at the configuration of KNX devices, including those that are broken down into multiple parts to make installation easier. The different types of bus devices - including memory capacities - is explained and the way the applications are stored in the devices is covered. Information on how devices reset when faced with low voltage and different device types is also included.
This module explores the use of KNX RF as either a standalone solution or as an extension to a wired KNX System. The impact of a building's fabric on signal strength will be covered along with how to extend the system with repeaters. This is followed by an in-depth look at the technology KNX RF uses including how multiple channels can be utilised to increase the reliability of systems. Comparisons between the current KNX RF S mode and the older KNX E mode will also be explained.
This module is delivered face to face. The practical course how to use ETS to program KNX using lighting and shading examples, how to run diagnostics with ETS, and finishes with the theoretical and practical certification exams. Please note that the online modules must be completed prior to attending this in-person training.
