Description
Introduction
This document describes the integration of BACnet MSTP and BACnet IP installations into KNX TP-1 home
automation systems using the Intesis KNX – BACnet Client gateway.
The aim of this integration is to make accessible BACnet system signals and resources from a KNX home automation
system, as if it was a part of the own KNX installation and vice-versa.
From BACnet point of view, Intesis acts as a BACnet client device, able to subscribe (COV), or perform periodic
polling and writes on configured BACnet objects. BACnet points’ values are available through its KNX interface,
acting in the KNX system as one more KNX device in it.
Configuration is carried out using the configuration software IntesisTM MAPS.
This document assumes that the user is familiar with KNX and BACnet technologies and their technical terms.

Functionality
From the BACnet system point of view, after the start up process, Intesis subscribes to configured BACnet points or
reads them continuously from their respective BACnet server devices and updates in its memory the value of the
present_value property received from them.
Every one of the present_values is associated to a KNX group object, associated in turn to one or more KNX Group
Addresses. When change occurs in the KNX object, it will be transmitted to KNX TP-1 with its corresponding Group
Address.
Likewise, when change is received in a write-enabled KNX Group Object, change will be written to present_value
property of corresponding BACnet object associated with it (using WriteProperty BACnet service).
Therefore, INKNXBAC---0000 performs as a single KNX device in the KNX TP-1 network offering communication
objects to access the BACnet objects of the configured external BACnet devices.
In the continuous polling of the BACnet server, if an unresponsive BACnet server device is detected, the
corresponding virtual signal inside Intesis will be activated indicating communication error with the BACnet server
device. These virtual signals indicating communication status in real time with the BACnet devices are also accessible
from KNX as a KNX Group Object, like the rest of the points of the gateway.

2 BACnet interface
This section describes the BACnet part of the Intesis's configuration and functionality.
Description
BACnet server devices are represented in the form of Devices holding Objects, normally every physical device
corresponds to a logical one. The Objects can be of different type depending on the data and functionality the
represent: Analog Input, Analog output, Digital Input, etc. Up to 23 different types of objects. Note that Outputs are
objects meant to be written in the direction BACnet network to the device, and the opposite for Inputs (they are meant
to offer status information of the BACnet device). Value objects are bidirectional.
Every Object has different properties. The most meaningful one, and the one used to read and write values by Intesis
is the Present Value property, which indicates the real value of the object. Every Object of the same type in a Device
is identified with its associated Object Instance.
These are the possible BACnet objects supported by Intesis:

Every signal is identified with its associated Device + Object Type + Object Instance.
Intesis simulates a virtual BACnet device inside the BACnet network acting as client device in the BACnet system.
The communication with the rest of the BACnet devices is done via the Ethernet or MSTP (RS485) port of the gateway
which implements the BACnet protocol.
Intesis implements a single BACnet object of its own: this is, its BACnet Device Object, containing its BACnet Device
Identifier and basic properties of Intesis as BACnet device (name, firmware version, etc).
Using the configuration tool with Intesis it’s possible to scan the BACnet network for available devices and their
objects, which can later be directly added to your configuration. This facilitates the configuration process, avoiding
entering them manually.
BACnet/IP and BACnet MSTP physical layers are supported. Only one physical layer can be used at a time. This is,
if communicating to BACnet using BACnet/IP, BACnet MSTP cannot be used, and viceversa.

BACnet/IP
Main parameter to set up for BACnet/IP, additional to basic IP settings (IP, netmask, default gateway) is the
communication port. Intesis uses port 47808 (0xBAC0) by default and it can be changed at configuration time.
When using BACnet/IP, device can also act as a Foreign Device (in order to be able to communicate with devices
that are in another network domain) and alternatively implement a BBMD itself (Bacnet/IP Broadcast Management
Device). This functionality facilitates communication of devices in other networks with the devices in the network
where Intesis is installed.
Communication with BACnet/IP excludes possibility of communicating with BACnet MSTP from Intesis.
BACnet MSTP
When choosing BACnet MSTP device needs to be associated with a MAC address (address within the MSTP network
segment), to be configured with configuration software.
Following baud rates are supported for MSTP line: 9600, 19200, 38400, 76800, 115200 or Autobauding (autodetect).
Standard wiring guidelines for EIA485 apply for the BACnet MSTP line.
Communication with BACnet MSTP excludes possibility of communicating with BACnet/IP from Intesis.
