1. Description

1.1 Introduction

This document describes the integration of ASCII enabled systems with BACnet ASHRAE
135 – 2001 Annex J - BACnet/IP protocol compatible devices or systems using the gateway
IntesisBox ASCII Server - BACnet IP client.

This document assumes that the user is familiar with BACnet technology and technical
terms.

From now on, and with the aim of easy the read of this document, the word "IntesisBox"
and "gateway" is used instead of IntesisBox ASCII Server - BACnet IP client gateway. And
any other use of the word "gateway" not meaning IntesisBox ASCII Server - BACnet IP
client will be specifically indicated.

The aim of this integration is to make accessible signals and resources of any BACnet IP
based system or device (for example Daikin VRV AC system) from any system capable to be
programmed to read and write simple text messages through EIA-232 serial port or
Ethernet TCP/IP port (for example Extron, LiteTouch systems).

For this, the gateway acts as a BACnet IP Client device in its BACnet interface,
reading/writing points of other BACnet IP device(s), and offering this point's values of
BACnet device(s) through its ASCII interface using simple ASCII messages. The readings
into the BACnet device(s) performed by the gateway can be by polling or by subscription
(COV).

1.2 Functionality

The integration operation is as follow:

From the BACnet system point of view, after the start up process, the gateway reads
continuously the points configured to be read by polling and also performs all the
subscriptions (COV) requests for points configured to be read by subscription, and updates
in memory all the values received from the BACnet system. These values received from
BACnet become available to be read by the ASCII system in any moment.

From the ASCII system point of view, after the start up process of the gateway, IntesisBox
waits for any query (ASCII messages requesting readings of points or ASCII messages
requesting writings of points), and acts according to the message received. See ASCII
interface section for details about this ASCII messages.

Also, whenever a point changes of value (due to a change in the BACnet point associated)
the gateway will send an ASCII message informing about new value for the point, but only if
the point is configured to send this type of spontaneous messages.

2. ASCII interface

This section describes the ASCII interface of the IntesisBox, its configuration and
functionality.

2.1 Description

The gateway can be connected to any ASCII enabled device using its EIA-232 interface
(DB9 connector DTE) or TCP/IP (Ethernet connector), and offers through this interface the
possibility of supervision and control of its internal BACnet points using simple ASCII
messages.

On receiving messages corresponding to write commands in its ASCII interface, the
gateway sends the corresponding write command message to the BACnet device associated.

When a new value for a point is received from BACnet, the corresponding ASCII message
indicating the new value will be sent through the ASCII interface, but only if the point is
configured for sending this "spontaneous messages", if it is not configured to do so, then
the new value will be available to be polled in any moment from the ASCII enabled device
connected to this ASCII interface. This behaviour of sending or not through the ASCII
interface the new values received from BACnet is configurable individually per point into the
gateway.

The communication parameters of this ASCII interface are the following:
Baud rate: configurable (1200 bps ... 57600 bps).
Data bits: 8.
Parity: None.
Stop bits: 1.

The ASCII messages used to read/write points into the gateway through this interface are:

Message to read a point's value:

>Daaaa?\r

Where:
aaaa is a 4 digits number indicating the point's address inside the gateway (see point
addresses details below in this document).
\r means carriage return character (HEX 0D, DEC 13).

Message to write a point's value:

>Daaaa=vv\r

Where:
aaaa is a 4 digits number indicating the point's address inside the gateway (see point
addresses details below in this document).

vv is the desired value for the point (it can be just integer or fractional, decimal point is
used to separate integer and fractional parts if the number is fractional).
\r means carriage return character (HEX 0D, DEC 13).

Message informing about a point's value (sent spontaneously by the gateway when
receiving a change from BACnet or sent by the gateway in response to a previous poll for
the point):

>Daaaa=vv\r

Where:
aaaa is a 4 digits number indicating the point's address inside the gateway (see point
addresses details below in this document).
vv is the actual value of the point (it can be just integer or fractional, decimal point is used
to separate integer and fractional parts if the number is fractional).
\r means carriage return character (HEX 0D, DEC 13).

Messages to indicate erroneous actions:

>E01\r Is returned when trying to read a point not configured in the gateway.

>E02\r Is returned when trying to write a point not permitted to be written.

2.2 Points definition

Every point defined in the gateway has the following ASCII features associated to it, which
can be configured (optionally or mandatory depending on the feature):

Feature

Description

Signal

Signal or point description. Only for information purposes at user level.

Spontaneous *

Determines if any change of value for the point received from BACnet
will generate a spontaneous ASCII message to send through the ASCII
interface informing about the new value.

Active *

If activated means that the signal is active for the gateway, if not
activated is like signal not defined. It allows you to deactivate signals
without the need of delete them (useful for future use of this signals).

* Configuration for this feature is mandatory.

3. BACnet interface

3.1 Description

The BACnet systems 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 their task: analog input, analog output, digital input, etc, up to 23 different types of
objects. Every Object has different properties, the one more commonly used, and the one
used to read and write values in the gateway is the Present Value property that 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 signals supported by the gateway:

Object Type

Property

Description

Analog Input

Present Value

Analog signal. i.e. Ambient temperature.

Analog Output

Present Value

Analog signal.

Analog Value

Present Value

Analog signal. i.e. Temperature set point value.

Binary Input

Present Value

Digital signal. i.e. ON/OFF status.

Binary Output

Multistate Input

Present Value

Multistate signal. i.e. Working mode status.

Multistate Output

Present Value

Multistate signal.

Multistate Value

Present Value

Multistate signal. i.e. Working mode command.

Multistate signals represent integer values, the same than binary ones but with more than 2
possible statuses. Input signals are read only signals.

Every signal is identified with its associated Device + Object Type + Object Instance.

The gateway simulates a virtual BACnet device inside the BACnet system acting as one
more device of the BACnet system. The communication with the rest of the BACnet devices
is done via the Ethernet port of the gateway which implements the BACnet IP protocol.

4. LinkBoxBacnet. Configuration & monitoring tool for IntesisBox

4.1 Introduction

LinkBoxBacnet is a Windows compatible software tool developed specifically to monitor and
configure IntesisBox BACnet IP series gateways. It is possible to configure all external
protocols available for IntesisBox BACnet IP and to maintain different customer’s
configurations based on a LinkBoxBacnet project for every different installation. Maintaining
always on hard disk a copy of the last configuration files for every external protocol and
customer, that is to say for every project.

From LinkBoxBacnet, as well as configure the integration signals list and connection
parameters for every external protocol, it is permitted also to select the serial port to use to
connect to the gateway and the use of some tools for monitoring and debugging de device.
Some of these tools will be explained in this document but only some of them, the rest of
available debugging tools and commands will not be explained here because they are for
exclusive use under the recommendations of Intesis Software technical support.

LinkBoxBacnet allows configuring all IntesisBox BACnet IP series independently of the
external system or protocol used. For every external system, LinkBoxBacnet has a specific
configuration window. Periodically, new free versions of LinkBoxBacnet are released
incorporating the latest developed integrations for external systems.

4.2 Project definition

The first step to do, in LinkBoxBacnet for a new installation, is to create the installation’s
project giving a descriptive name to it. When you create a project, a new folder is created
with the name of the project containing the configuration files needed depending on the
external protocol selected for the project. It is strongly recommended that you create a new
project for every installation, if not, overwriting of configuration files of previous
installations using the same external protocol may occur, loosing the configuration data for
those previous installations. The projects folder is located in AppFolder\ProjectsBacnet,
where AppFolder is the installation folder of LinkBoxBacnet (by default C:\Program
Files\Intesis\LinkBoxBacnet). Inside the projects folder, a new folder will be created for
every project defined in LinkBoxBacnet with the files needed for the project.

When you open LinkBoxBacnet, the project selection window will appear inviting you to
select a project or create a new one. A demo project for every external protocol supported
is provided with the standard installation of LinkBoxBacnet. You can create a new project or
select a demo project based on the external protocol desired, and create a new one from
the demo one selected.

Project selection window

To create a new project, select a project using the same external protocol you want to use
in the new project and push New button. You will be prompted to create a copy of the
selected project (useful for similar installations) or create a new one.

If you select Yes you will be prompted to specify a name and a description for the new
project that will be based on the same external protocol than the selected one. If you select
No you can specify a name, a description and an external protocol to use from the list of
available external protocols.

On Accept, a new folder will be created inside the projects folder with the name given to the
project, this folder will contain the template configuration files if the project is a brand new
one, or a copy of the configuration files if it is a copy of a selected one.

A description of the files created for an ASCI-INT protocol based project can be found in
section Files below in this document.

From all the possibilities of LinkBoxBacnet, only changes in configuration for the integration
and configuration file generation can be performed while disconnected from the gateway
(working off-line), allowing you to do these tasks in the office more comfortably. Before any
monitoring or downloading action to the gateway can be performed, the connection between
the gateway and the PC running LinkBoxBacnet must be established (working on-line). To
do so follow these steps:

1. Make sure the gateway is powered-up a correctly connected to the ASCII system via the

EIA-232 interface or Ethernet interface and to the BACnet system via the Ethernet
connection (consult details for connection and pin assignments in section Connections of
this document).

2. Connect a free PC serial port to the gateway's serial port marked as Pc Console. (Use

the standard serial cable supplied with the IntesisBox or make your own cable following
the pin assignments specified in section Connections in this document).

If using the Ethernet connection, connect an Ethernet cable between the Pc Console
port of the IntesisBox and the PC or the corresponding Ethernet interface (Check
Connections section in this document for more information).

3. If using the EIA-232 Serial port, select in LinkBoxASCII the PC serial port used for the

connection to IntesisBox. Use menu Configuration -> Connection.

If using the Ethernet (IP/TCP) port, select in LinkBoxASCII the IP option with the
corresponding IP.

4. Check the checkbox off-line under the menu bar (it will change automatically to on-line)

and LinkBoxBacnet will ask for INFO about the gateway connected to it via the serial
connection, if the connection is ok then the gateway will respond with its identification
(this can be monitored in the IntesisBox Communication Console window, as showed
below).

Once connected to the gateway, all the options of LinkBoxBacnet are fully operative.

To monitor the communication between the gateway and the BACnet system, select the
menu View -> Bus -> Bacnet/IP. The BACnet communication Viewer window will be opened.
This window shows in real time all the communication frames between the gateway and the
BACnet device(s) as well as debugging messages referent to the BACnet/IP protocol sent by
the gateway.

4.8 Files

LinkBoxBacnet saves the IntesisBox configuration in the following files inside the project
folder:

PROJECT.INI

.ini file containing general information referent to the project

ASCI-INT.INI

.ini file containing the information referent to the connection window and
other special adjustments

ASCI-INT.DAT

Text file (tab separated values) with the signals information (signals list).
This file can be edited (with Excel for example) to change the
configuration quicker and easier. Later on, when selecting Configuration -
> IntesisBox in LinkBoxBacnet, if the changes have been made respecting
the correct format, all the changes in the configuration done from Excel
can be seen in the signals list.

ASCI-INT.LBOX

Binary file created from the information in the files described above. This
is the file uploaded to the gateway.

It is strongly recommended to back up the project folder containing these files in external
media, once the installation process is finished. This way you will be able to do future
configuration changes in case of reinstallation of LinkBoxBacnet due, for example, to a
failure of the hard disk in the PC where LinkBoxBacnet was previously installed.

The configuration cannot be downloaded from the gateway to LinkBoxBacnet, only
can be uploaded; the upload file ASCI-INT.LBOX does not contain all the
integration information, as for example the signals description.

4.9 Functionality considerations

IntesisBox returns some useful information about internal parameters in response to an
INFO command:

Referent to IntesisBox:

- Firmware version and serial number.

- Protocols versions.

Referent to BACnet side:

- IP address configured.

- NetMask configured.

- Default Gateway configured.

5. Setup process and troubleshooting

5.1 Pre-requisites

It is necessary to have the ASCII enabled device operative and ready to be connected to the
ASCII interface of IntesisBox. The ASCII massages to use to communicate to the gateway
(see format above in this document) should be configured in the ASCII enabled device.

It is necessary to have an Ethernet 10BT network connection near IntesisBox (network hub
or switch port) with all BACnet/IP devices connected to this Ethernet network.

Connectors, connection cables, PC for LinkBoxBacnet, and network hub or switch are not
supplied by Intesis Software for this standard integration. The items supplied by Intesis
Software for this integration are:

• IntesisBox gateway with ASCII protocol and BACnet IP Client protocol firmware loaded.

• Console cable. Standard DB9F-DB9M cable 1.8 meters long.

• LinkBoxBacnet software.

• Product documentation.

5.2 Setup procedure

1. Install LinkBoxBacnet on your laptop.

2. Install IntesisBox in the desired installation site. The mounting can be on DIN rail or

on a stable not vibrating surface (DIN rail mounting inside a metallic industrial
cabinet connected to ground is recommended).

3. Connect the EIA-232 or Ethernet cable coming from the ASCII enabled device c port

marked as ASCII EIA-232 or ASCII TCP/IP respectively of IntesisBox. Respect
always the maximum distance of 15 meters for this cable. (See details for this bus
cable in section Connections of this document).

4. Connect the communication cable coming from the network hub or switch to the port

marked as ETH of IntesisBox. (See details for this communication cable in section
Connections of this document).

5. Power up IntesisBox using a standard power supply 220/125VAC-12VDC/300mA for

example.

WARNING! In order to avoid earth loops that can damage the gateway and/or any
other equipment connected to it, we strongly recommend:

• The use of DC power supplies, floating or with the negative terminal connected to

earth. Never use a DC power supply with the positive terminal connected
to earth.

• The use AC power supplies only if they are floating and not powering any other

device.

6. Connect the EIA-232 cable coming from the serial port of your laptop PC to the port

marked as Pc Console of IntesisBox. If you prefer using the Ethernet connection,
connect the PC to the Pc Console port of the IntesisBox. (See details for this
communication cable in section Connections of this document).

7. Open LinkBoxBacnet, create a new project selecting a copy of the one named DEMO

ASCI-INT and give it the name desired, select the serial port used to connect to the

gateway (menu Configuration -> Connection) and switch working mode to on-line
(checkbox off-line/on-line). The IntesisBox identification must appear in the
IntesisBox communication console window as showed below.

8. Open the ASCII Communication Viewer window (menu View -> Bus -> ASCII), force

some point's polling from the ASCII device connected to IntesisBox, and check that
there is communication activity, some TX frames and some other RX frames. This
means that the communication with the ASCII device is ok. In case there is no
communication activity between IntesisBox and the ASCII device check that ASCII
device is operative and well connected to the IntesisBox.

9. Open the BACnet Protocol Communication Viewer window (menu View -> Bus ->

Bacnet/IP) and check that there is communication activity, some TX frames and
some other RX frames as showed in the figure below. This means that the
communication with the BACnet system is ok.

In case there is no response from the BACnet devices to the frames sent by IntesisBox
check that they are operative and reachable from the network connection used by
IntesisBox, check the IntesisBox's BACnet IP interface using any commercial BACnet
browser connected to the same Ethernet network. See details for the communication
cable between IntesisBox and BACnet system in section Connections of this document.

6. Configuring the integration in just two steps

6.1 Importing BACnet points list and configuring IntesisBox

The first step is to obtain, from the technical documentation of the BACnet device(s) to
integrate, the following information:

• Device number.

• A list of all the points wanted to be integrated, this list must contain for every point:

• Signal's descriptive name.

• BACnet object type.

• BACnet object instance.

Once this information has been collected, you can begin to configure the gateway:

• Create a New ASCI-INT based project as explained above.

• If there are few points to integrate you can use directly LinkBoxBacnet to add the points

and introduce the BACnet parameters into the appropriate columns, if a lot of points
have to be integrated it is recommended to use Excel to update the file containing the
signals list (ASCI-INT.DAT), we will explain here this process using Excel.

• Open the ASCI-INT.DAT file located under the project folder with Excel. This is a text file

with Tab separated fields, so configure accordingly the filters to open tab separated
fields text files in Excel.

• Introduce the point's parameters collected from the BACnet device(s) documentation

into the appropriate columns of the file, adding as many rows to the file as points
required. See example of file opened with Excel below.

PROTOCOLO=55-ASCI-INT

VERSION=1.0

CAMPOS=11

Follow these indications when filling the columns:

• Column 1: Auto-enumerate in increasing order (1,2,3…).

• Column 2: Enter the device number to which belongs the point (referenced the

list of devices defined in Connection Tab as explained in section 4.3, note that
this is not the device number configured in the BACnet device itself).

• Column 3: Enter the BACnet object type for the point, with the correct format

(see section 4.4 for details about correct formats). Consult BACnet device
documentation for details about object types for every point.

• Column 4: Enter always "85-Present Value".

• Column 5: Enter the descriptive name of the point

• Column 6: Enter the BACnet object instance for the point, a number. Consult

BACnet device documentation for details about object instances for every point.

• Column 7: Enter the point's address, a number between 1 and 9999, do not

duplicate addresses. We recommend you to auto-enumerate in increasing order
(1,2,3…).

• Column 8: Enter the signal direction for the point (0-R, 1-W, 2-R/W) according to

the BACnet object type also entered for the point, with the correct format (see
section 4.4 for details about correct formats).

• Column 9: Enter the signal type for the point (0-Ana, 1-Dig) according to the

BACnet object type also entered for the point, with the correct format (see
section 4.4 for details about correct formats).

• Column 10: Enter the "Spontaneous configuration" for the point (0-NoSpon, 1-

Spon) according to the functionality desired for the point, with the correct format
(see section 4.4 for details about correct formats and functionality).

• Column 11: Enter always "1-Yes".

• Save the modified file with Excel maintaining its original format (text file with Tab

separated fields).

• Open the configuration window from LinkBoxBacnet as explained above.

• Do not forget to enter the ASCII interface parameters and BACnet interface parameters

in Connection Tab as explained above.

• Select Signals Tab, and you should see here all the new rows introduced previously

using Excel in ASCI-INT.DAT file.

• Save the configuration, and generate the gateway configuration.

• Download the configuration file to the gateway as explained above.

6.2 Configuring the ASCII system to access the gateway's points

Once the gateway is configured and working, then the last step to do is configuring the
ASCII system to be able to write/read ASCII messages according to the format accepted by
the gateway and having in mind the address configured for every point. This must be done
by the engineer in charge of configuring and commissioning the ASCII system (LiteTouch for
example).

To calculate the Object Instance use the following formula:

Object Instance = (Indoor Unit Number X 256) + Point Number

Indoor Unit Number: 0..255
Point Number: 1..31

Example:

Indoor Unit Number: 1 (Remember 256 numbered 0..255)
Point Number: 9-RoomTemp

Object Instance = (1 X 256) + 9 = 265

Note: In the Daikin system configuration, sometimes the VRVs are configured as masters
and sometimes as slaves, the ones configured as slaves do not accept commands because
they work in parallel with their masters.

Important: With the standard installation of LinkBoxBacnet, there will be created some
example projects containing signals configuration for integration of Daikin VRV systems with
Daikin DMS502A51 BACnet Gateway.

Are the following:

BACnet Daikin 256 units. 256 VRV units with all the signals.

Create a copy of the project most suitable for your application and, after that, it will only be
necessary to activate and select an internal Point Address for those signals needed for your
integration.

Requirements: The information needed to configure the integration is:

• The Daikin Gateway must be configured in mode BACnet/IP

• IP address of the Daikin Gateway

• Net Mask of the Daikin Gateway

• UDP Port of the Daikin Gateway

• Device number of the Daikin Gateway

• List of all the VRVs of the installation containing the physical location in the building and

the number (0..255) for every VRV
List of the slave VRVs and their corresponding masters (no commands supported by these
slave VRVs
