1. Description

1.1 Introduction

This document describes the integration of KNX TP-1 (EIB) systems with BACnet ASHRAE

135 – 2001 Annex J - BACnet protocol compatible devices or systems using the gateway

IntesisBox BACnet/IP Server - KNX.

This document assumes that the user is familiar with KNX and BACnet/IP technology and

technical terms.

From now on, and with the aim of easy the read of this document, the words "gateway" or

“IntesisBox” are used instead of IntesisBox BACnet/IP Server - KNX. Any other use of the

word "gateway" not meaning IntesisBox BACnet/IP Server - KNX will be specifically

indicated.

The aim of this integration is to make accessible KNX system signals and resources from a

BACnet/IP based control system or device, as if it was a part of the own BACnet system and

vice-versa. For this, the gateway acts as a BACnet/IP Server device in its BACnet interface,

allowing other BACnet/IP devices to perform subscription (COV) requests, and also read and

write its internal points. From the KNX system point of view, the gateway simulates a KNX

device and acts as if it was one more device into the KNX system.

1.2 Functionality

The integration operation is as follow:

From the KNX system point of view, in the startup process of the gateway and also after a

detection of a KNX bus reset, the gateway polls the KNX signals configured to be updated in

this situation and maintain the received values in memory to be served to the BACnet

system when requested. Also listen for any KNX telegram related to the internal points

configured in it and acts accordingly to the configuration of the related point.

From the BACnet system point of view, after the startup process, the gateway listens for

any subscription (COV) request, serves any polling request or performs any writing request

of its internal points received from BACnet system. The values received from BACnet

become available to be read (and when applicable, written) by the KNX system and vice-

versa.

If a signal has been configured as of type “T” Transmit (in the KNX part), any new value for

the signal coming from the BACnet system is notified to the KNX system with the

corresponding telegram.

When, from the KNX system, a signal is changed (written from any other KNX device for

example), the new value is updated in the gateway's memory and, if this signal is

associated to a BACnet active subscription then the new value will be sent to the

subscripted BACnet device(s).

Also the following functionality is supported by the gateway:

For every point, in the KNX part, one main group address and different listening group

addresses can be defined. With this, from KNX, every point can be addressed not only using

its main group address but also using the other defined listening addresses for the point.

Any change in a gateway's point with the feature “T” activated (in the KNX part), will force

the transmission of this point value with the corresponding telegram to the KNX system.

When the gateway starts up, or after an KNX bus reset, all the points with the feature “U”

or "U2" activated (in the KNX part) will be forced to be read in the KNX system to update its

values in the gateway’s internal memory.

Any point with the feature “W” activated (in the KNX part), can be written in any moment

from the KNX system.

Any point with the feature “R” activated (in the KNX part), can be read in any moment from

the KNX system.

All the mentioned features (W,R,T,U) related to the KNX interface are deeply explained in

section 5.1.2.

KNX EIS (data types) supported are: switching (1 bit), dimming (4 bit), float (16 bit),

scaling ( bit), drive control (1 bit), priority (2 bit), float IEEE (32 bit), counter ( bit),

counter (16 bit), counter (32 bit), ASCII char ( bit).

2. Interfaces

This section gives the reader an idea on how a KNX system/installation is integrated with

IntesisBox BACnet. It is not meant to provide an in-depth explanation on how BACnet or

KNX technology work as understanding the protocol principles is assumed throughout this

document.

The IntesisBox behaves as a regular BACnet device inside the BACnet system integrating all

the KNX devices. Note that each datapoint defined on IntesisBox will have two associated

data types:

•One data-type, related to the BACnet/IP protocol of the IntesisBox

•And another data-type, related to KNX side of IntesisBox

Conversions of data values from KNX to BACnet/IP data-types (and vice versa) are

internally performed at application level of IntesisBox, and keeping the highest possible

level of precision, with the restrictions of the data-type itself. Further detail on behavior and

data-types of the BACnet/IP and KNX interfaces of IntesisBox is given in the following

sections.

All configuration of IntesisBox BACnet is done using software tool LinkBoxBacnet. This tool,

covered in depth in section 5, is used to define the KNX and BACnet related parameters on

each of the datapoints defined in IntesisBox.

2.1 BACnet

The IntesisBox integrates all the KNX devices in a single BACnet device. The communication

with the other BACnet devices is done via the Ethernet port of the gateway which

implements the BACnet ASHRAE 135 – 2001 Annex J - BACnet protocol.

In addition, IntesisBox can be configured to be a BBMD (BACnet Broadcast Management

Device). See details in section 5.1.3.

The supported BACnet Objects and Building Blocks can be found in the PICS document

available on the web:

http://www.intesis.com/pdf/IntesisBox_BACnet_IP_Server_KNX_PICS.pdf

Configuration of all BACnet/IP parameters of IntesisBox and their links to KNX using

LinkBoxBacnet software tool is covered in section 5.1.

2.2 KNX TP-1 (EIB)

IntesisBox BACnet/IP Server - KNX supports the KNX TP-1 physical layer, as defined in the

KNX standard. It behaves as one more device of the KNX system, with the same

configuration and functional characteristics as other KNX devices.

KNX TP-1 (EIB) bus provides a 30V DC current, which can even directly power certain low-

consumption KNX devices. IntesisBox does not drain any significant current from the KNX

bus - it has a separate own power supply. Another important electrical aspect is that the

KNX TP-1 (EIB) port of IntesisBox is optically isolated (~2500Vrms AC) from all its other

ports (EIA232, EIA4 5, Ethernet) and power supply.

At logical level, all KNX devices feature an interface of communication objects, by which

their functionality is abstracted. As a basic example, a KNX interface of an AC indoor unit

would typically consist of an interface of datapoints such as “On/Off”, “Setpoint

temperature”, “Operating mode”, etc.

Associations between communication objects from different KNX devices are actually done

by means of so-called group addresses.

KNX telegrams within a working KNX installation are always addressed to a certain KNX

group address. Typically, whenever a communication object on a KNX device changes its

value, the new value is updated to the bus, by sending a “write” telegram addressed to its

associated group address. The rest of KNX devices in the installation that have a

communication object associated to this group address will act accordingly on reception of

the new value.

Other operations are possible. KNX devices can also decide to read the current value of the

communication objects, by sending a “read” telegram to a certain group address (previously

known to be associated to the targeted comm. object). This operation is performed by many

devices on bus start-up or recovery – in this way, the device gets the latest value of the

group addresses it has associated right from its start-up.

Each datapoint defined in IntesisBox KNX configuration needs to have at least a single KNX

group address associated with it. This group address will be used either for sending updates

to KNX of the datapoint value (that have been generated on the other BACnet/IP interface

of the IntesisBox), or receiving updates from KNX of the datapoint value (that will be

propagated to the BACnet/IP side in this case)

From the point of view of KNX functionality, each datapoint of IntesisBox can hold following

group address associations:

•A single KNX group address with which update/write telegrams will be sent,

whenever the datapoint changes (as a result of a change coming from the other

interface of IntesisBox, BACnet/IP in this case).

•One or more KNX group addresses from which this datapoint of IntesisBox will be

updated/written from the KNX installation (resulting in a change to the other side of

IntesisBox, BACnet/IP in this case).

•A single KNX group address from which IntesisBox will read the object value on KNX

bus recovery / IntesisBox start-up.

Behavior of IntesisBox’ datapoints with regard to their associated group addresses is

defined by means of flags (R, W, T, U and U2), explained in section 5.1.2.

Additional to the binding aspect commented above, it is also important to notice that each

KNX communication object has a defined EIS type. The EIS type of a communication object

defines the bit length and coding of the data it represents. Communication objects

associated by means of a group address need to match the same EIS type, in order to

communicate consistently.

So, at configuration time it is required that for each datapoint configured on IntesisBox an

EIS type is defined. Datapoints on IntesisBox BACnet support the following EIS-types:

•EIS1 - Switching (1bit raw)

•EIS2 - Dimming (4bit raw)

•EIS5 – Value (16bit – floating type)

•EIS6 – Scaling ( bit – scaled 0%-100% in values 0-255)

•EIS7 – Drive Control (1bit raw)

•EIS – Priority (2bit raw)

•EIS9 – IEEE 754 float (32bit – floating type)

•EIS10 – 16bit Counter (16bit raw)

•EIS11 – 32bit Counter (32bit raw)

•EIS13 – ASCII char ( bit raw)

•EIS14 – bit Counter ( bit raw)

ETS3 or ETS4 software tools are not used to configure IntesisBox. Though, it’s typical that

the choice of which KNX group addresses to use is restricted or defined by an ETS-based

project. If that’s the case, the KNX installer/integrator needs to provide the set of group

addresses prior to doing the configuration of datapoints in LinkBoxBacnet.

Also, a dummy ETS application is provided by Intesis Software (section 6), which can be

imported into ETS. This application is nor downloadable into IntesisBox BACnet neither

usable for IntesisBox configuration. Rather, it poses as a means of having a device in the

ETS project representing the IntesisBox BACnet and its own datapoints/communication

objects, and to which group addresses are associated.
