Technical Data Sheet

KNX Package 2.0

The ProSyst KNX package provides an OSGi-integrated API to accessing devices connected via KNX - the

worldwide open standard for home and office building control. The features included in the KNX package allow

the users to connect and communicate over the KNX network and to manage appliances such as lighting, blinds /

shutters, security systems, energy management, heating, ventilation and air-conditioning systems.

Features

Benefits

•

OSGi-based, multi-platform, Java API to

accessing the KNX network

•

Seamless integration of the KNX network in

the OSGi Environment

•

Various methods to access the KNX network

- KNX/IP, USB or Serial connection; as well

as Weinzierl Net'n'Node protocol

•

With the build-in DPT support, the user can

focus on the control of devices, instead of in

the implementation details

•

Build-in support for EMI1, EMI2 and

Common EMI (cEMI) frame formats.

Automatic conversion to the correct frame

format used by the connecting driver

•

The representation of a group-to-DPT

mapping as a Control Unit adds an abstract

layer that allows inter-connectivity and

interoperability between heterogeneous

networks

•

Ready to use classes for link-layer (LData),

management, bus-monitor and raw frames

•

Pre-defined classes for controlling KNX

groups of devices. An implementation of the

most common Data Point Types (DPT)

•

A Mapper Service, that allows to define the

network topology and bind a group address

to DPT functions

KNX is a standard that provides a common way to

manage air-conditioning, light sources and other home

or office systems. As the EIB (European Installation

Bus) standard grew into KNX, the KNX package

provides a KNX bus-communication stack, but it is still

compatible with the existing EIB networks.

standard transmission media. It is commonly used for

the communication with sensors and actuators,

enabling functions such as the control of lighting,

heating, window blinds, air-conditioning, load

management, signaling, monitoring, alarms, etc.

ProSyst KNX Solution Details

KNX is a protocol for digital communication between

smart devices. KNX offers flexible tree architecture for

devices with network management features via

communication model. The incoming frames, received

from the KNX bus are delivered through the OSGi

Event Admin service. It allows the interested parties to

define a set of filters and receive only these events,

which they need to handle.

network by linking a group address to DPT

functions.

•

An extra module, called DPT Loader, which

simplifies the above task, by allowing to define the

network in a simple XML file, and to deploy it in a

bundle.

The API provides transparent conversion from one

frame format to another. This particular feature is used

by the lower-level drivers, which typically support only

one of the supported frame formats.

•

Integrated loop-back driver, which supports group

communication and allows to create and run tests

in offline mode.

Available KNX Communication Drivers

KNX Demos

The KNX Package supports different methods to

connect to the KNX bus:

The KNX package has two demos:

•

Through the KNX/IP protocol.

•

KNX Control Demo. It is a Control Unit,

implemented on top of the ProSyst KNX API. It

sends data frames to the bus, including DPT data.

It supports a limited set of multicast, unicast and

broadcast messages.

•

By using a USB port (the connected device must

comply with the KNX USB/HID specification -

"AN037 v04 KNX on USB AS").

•

By connecting to the Weinzierl Net'n'Node tool and

using its build-in methods to connect to the bus.

•

KNX DPT Demo. It illustrates the usage of the

KNX Mapper & Loader Components. The demo

provides a single XML file that describes the

network and provides the mapping group address

to DPT functionality. For each mapping, a control

unit is automatically registered and the

functionality becomes immediately available

through the Control Unit Browser.

•

Through a serial/Pei16 interface.

•

Additionally, a loop-back simulation driver is

available for testing the products based on the

KNX package.

Control of Devices

The KNX package offers modules implementing

common functionality needed to control a group of

devices connected on the same KNX bus:

Additional capabilities and packages of mBedded

Server and other ProSyst products are explained in

the data sheets available for each product.

•

The build-in DPT library provides common basics

for controlling different functions of the KNX

devices.
