The DESIGO building automation andcontrol system: the powerful, open system
With its modular design, the DESIGO building automation and control
system offers virtually unlimited scope for operation, monitoring and
control. The scalable system covers everything from small, stand-
alone buildings to large, networked building complexes. DESIGO is
ideal not only for typical HVAC systems, such as heating, ventilation,
air conditioning and sanitation, but also for all other building services,
such as lighting and electricity, or fire and security.
Open to integration
The open system architecture is widely supported, making it possible to integrate third-
party systems at all three levels of the system. Even for the exchange of information
between system components, DESIGO uses well-established standard protocols,
adopted throughout the world:BACnet both for communication between the management level and the automation
stations, and for communication between one automation station and another.
LONMARK for communication at the room automation level.
DESIGO also supports components and systems with interfaces such as Ethernet,
LON, EIB/KNX, Modbus, M-bus and OPC.
Easy to operate
DESIGO is distinguished by its exceptional ease of operation. The attractive local
operator units offer large fonts, and provide clear user guidance and a graphics-based
display. Operation from the management station is based on the Microsoft Windows
operating system and designed to take account of ergonomic principles.
DESIGO makes use of Web technology both at the automation level and at the
management level. Fault messages can be received and acknowledged with cost-
efficient standard equipment such as Web-Pad, PC or mobile phone. The same
technology can be used to retrieve data, trend information, statistics and reports,
irrespective of the location of the user.
Long-term investment protection and economy at every stage
With its modular design, the DESIGO building automation and control system is an
open system in every respect open to existing systems, open to future developments
and open to other manufacturers systems. This uniquely versatile range of options for
expansion ensures long-term protection of your investments combined with optimumadded value.
The scalable system: for all projects from small to large
DESIGO is suitable for all projects, no matter how small or large. Its modular design
satisfies the requirement for optimum flexibility.Both the size of the management system
and its functional scope can be readily matched to all manner of customer requirements.
The advantage is that it allows you to choose only functions and components that you
really need. And if the need arises, the system can always be expanded later, stage by
stage and at all levels.

The DESIGO system topologyThe DESIGO system can be divided into three levels: the management level, the
automation level and the field level. By virtue of distributed intelligence, each of these
levels operates both autonomously and in a network.
The principal DESIGO system components:
DESIGO INSIGHT, the management
station, for higher-level operation and
monitoring, graphics-based display of the
process, automatic alarm distribution and a
wide range of different data analysis
options.
DESIGO PX, the automation system for
control and for operation and monitoring of
the primary plant. With PX-WEB, the
automation system can be operated via a
Web client.
DESIGO RXC, the room automation
system, for control of comfort conditions in
individual rooms, and for operation of
lighting and blinds.
DESIGO OPEN, for the integration of a
wide variety of plant at all levels of the
system.

Trend/History
Fully integrated trend data processing allows effortless evaluation and analysis of
real-time (online) data and (offline) historical data. The trend feature facilitates the
monitoring and fine-tuning of the plant. In the DESIGO system this feature is
implemented in compliance with BACnet standard.
Data for trend analysis can be logged in a variety of different ways, satisfying a whole
range of requirements:
Trend logging options: Sampling options:
Continuous logging
Single run
Transient run (logging over a given period)
Polling
COV polling (Change of Value)
Event-driven polling
Trend graphs can be displayed both on the PXM20 operator unit and on the
management station. The management station also allows displays in color and in 2D
or 3D.

Alarm management
One of the most important features of a building automation and control system is the
ability to generate alarms automatically if a fault occurs; these faults may arise in the
HVAC and other plant, or in the automation system itself. The management of alarms
(generation, display and handling) must be simple, efficient and consistent at all levels
of the system. DESIGO uses the BACnet alarm functions, and supports the following
three types of alarm with up to 256 alarm priority levels: Simple alarms (for alarms not requiring user interaction)
Basic alarms (for alarms requiring acknowledgment)
Extended alarms (alarms requiring acknowledgement and reset)
When an alarm occurs, it is automatically detected, registered and transferred to
operator units such as the PXM20 or PX-WEB, or to the DESIGO INSIGHT
management station. Informative alarm messages are also transmitted to remote
devices such as mobile phones, fax machines, printers or PCs and Web browsers, via
SMS and e-mail. Clear alarm lists provide a view of all pending and time-stamped
alarms at a glance, and permit straightforward processing. Operators are alerted to
incoming and pending alarms by means of pop-up windows and audible and visualsignals.
Alarm messages
Alarms are transferred on the basis of time, priority and/or plant type, using an
outstandingly powerful alarm routing system at the management station. This ensures
the uninterrupted routing of alarms, irrespective of whether or not there is an operator
sitting at the management station. Users are supported in their work by various
overview options which help ensure a fast and correct response even in critical alarm
situations.

Scheduler / Calendar
One of the basic functions of a building automation and control system is time control of
procedures and processes.
The plant in the building is operated on the basis of business and working hours, and
holidays.
Scheduler programs ensure that the heating and lighting are switched off automatically
at the end of the working day, that the temperature in the building is reduced at night,
and that the plant is not kept running for longer than necessary. They can also be used
to switch off the air conditioning in certain rooms during holidays.
The ideal scheduler programs help save energy and increase the service life of the
plant. This is another area where DESIGO excels with its straightforward and
exceptionally user-friendly operation.
Saving energy and increasingthe service life of plant
Time-switching operations in the DESIGO building automation and control system are
implemented in accordance with the BACnet standard, using the BACnet objects
"Schedule" and "Calendar" for flexible operation of the building. From simple 7-day
schedules to recurring exceptions, these powerful functions make programming easy.
Through the use of standard BACnet functions, the BACnet scheduler programs can beoperated system-wide from the user-friendly operator units PXM20 and PX-WEB and
from the DESIGO INSIGHT management station.
Scheduler program in the PXM20 operator unit and on the DESIGO INSIGHT management station
For safety reasons, schedules and calendars are stored in the automation station, so
that in the event of a network or PC failure, the automation level can continue to
operate autonomously.

Access rights
Access rights can be used to filter information from the plant and system based on the
individual requirements of a user. The resident engineer or the service engineers, for
example, only have access to the information they strictly need. A distinction can also
be made between readaccess and write access. Certain users may be able to read a
value but not modify it, while other users may have extended access rights, enabling
them both to read and to modify values.
Only authorized personnel are granted access to the system via the operator units.
When a user enters a user name and password, the system verifies the associated
access rights and enables access to the relevant plant. Read and write access rights
can be defined in detail, down to individual information points.
Freely-definable access rights
The following classes of access are supported in the DESIGO system:
InternalUsers supported system-wide
Extended service
Basic service
Administration
Extended operation
Standard operation
Basic operation
In addition to the above, it is possible to enable or disable the use of the various
applications, access to individual graphics pages and access to entire sites from the
management station for specific user groups. The tailoring of the environment to each
user ensures clear areas of responsibility and answerability, so simplifying cooperation
between the various user groups.

Communication Networks
Communication standards: specifically designed for building services
With the BACnet (Building Automation and Control network) open communications
protocol, compliant devices can be interconnected at low cost. The worldwide BACnet
standard was developed specifically for the needs of building services, under the
auspices of ASHRAE (the American Society of Heating, Refrigerating and Air-
Conditioning Engineers). BACnet networks provide all subscribers with access to all the
data and functions of the connected devices.
DESIGO uses the two worldwide standard protocols BACnet and LONMARK for the
exchange of information among its own system components. The BACnet
communication protocol is used for the exchange of information between one DESIGO
PX automation station and another, and between DESIGO PX and DESIGO INSIGHT.
DESIGO uses Ethernet/IP, LonTalk or PTP (point-to-point) as the transport medium.
For communications at the room automation level, DESIGO RXC uses the LONMARK
standard.
BACnet / LONMARK
In the case of BACnet/IP over Ethernet, the standard transport protocol UDP is used,since BACnet already provides sufficient mechanisms for the control of data transport.
Like TCP, UDP is a transport protocol, but unlike TCP, it is a wireless protocol.

Pop-up windows
The pop-up window is an important means of attracting the attention of the user in the
event of an alarm. Incoming alarms are displayed in a pop-up window that opens on the
Windows desktop and appears in the foreground of all other applications (including
third-party applications).
If several alarms occur, they are displayed one after the other. To further alert the user
to the alarm with an audible signal, an audio file (.wav) can be added to each alarm
window definition.

Alarm Router
The Alarm Router application provides for highly effective building management.
Important messages or events in the building automation and control system are
transferred to specific receivers without the need for any user action at the
management station. Alarm Router is a background application which starts when
DESIGO INSIGHT is started, whether or not a user or site is connected. Alarms and
important system events can be transferred via the following media:
Printers
Fax machines
Pagers
Mobile phones
E-mail systems
Alarms can be grouped according to various criteria. A routing table defines the
conditions under which these alarm groups are to be routed to the assigned receivers.
In the event of connection problems, the alarm messages can be transmitted to
alternative receivers. The criteria include the following, for example:
Criteria for the transfer ofalarms
Time (e.g. at night, switch to the printer in the security guard's office) Responsibility for the site (e.g. send a fax to the company responsible for
maintaining the air conditioning)
Urgency of the alarm (e.g. only call emergency service by pager in the case of high
priority alarms)

Log Viewer
Log Viewer provides users with access to all events that have occurred within the
system. Events and user activities are archived in chronological order in the log
database and can be viewed whenever required.
The data logging system is a background service performed by the Event Handler in
DESIGO INSIGHT, which continuously logs reported events as follows:
Event Handler
Alarm events from the process level, such as plant alarms and high priority warnings.
The alarm is logged when it occurs, and thereafter upon acknowledgment, reset and
return to normal.
System events from DESIGO INSIGHT management stations and PX automation
stations. Examples are disconnection, dial-up, start-up, shutdown, hard-disk
monitoring, battery checks etc.
User events for reporting user activities on management station. These include
authorized and unauthorized user log-in procedures and the modification of values,
parameters and setpoints etc.
Status events from the process level, such as plant ON/OFF etc.
The user interface of Log Viewer has the same look & feel as the Alarm Viewer and isbased on the same versatile sort and filter functions.
Functions in Log Viewer:
Query-configurations can be stored and re-
used. The status bar displays the current filter
and sort status
The Log Viewer display is divided into five tabs:
All, Alarm, System, User and Status, enabling
the user to pre-select events of a particularcategory
Columns can be flexibly rearranged, re-sized or
hidden as required
The events logged for a specific object, such as
events associated with a given site, automation
station or data point, can be located quickly in
the left pane (System Browser). The SystemBrowser can be hidden.
The logged data is stored on a Microsoft SQL server or in an MSDE database, and
protected by password.
Log and trend data archiving
The archiving function serves to remove data from the runtime databases. This is
necessary firstly to create space for new data in cases where storage capacity is
normally limited, and secondly, to store the data in a suitable form for retrieval at a later
date. The removed data is archived in a safe location for later retrieval and display as
necessary. Data is archived in DESIGO INSIGHT automatically on the basis of time orquantity of data accumulated, or manually by the user.

DESIGO INSIGHT Web Access
Web Access provides access to the system via a browser, using integrated Web
technology.
This cost-effective solution reduces the cost of training, software installation and
maintenance. DESIGO INSIGHT Web Access facilitates and encourages the simple
distribution of building information to those who need it, and at the point where it is
needed.
Unlike many other Web-based solutions, Web Access does not use any script
components on the client side. All processing takes place on the Web server. This
means that client browsers can work with Web Access without having to download any

The DESIGO PX automation level
The DESIGO PX automation system meets all the requirements associated with the
control and monitoring of heating, ventilation, air conditioning systems and other
building services. The most striking features of DESIGO PX are the scalability of the
system with its programmable automation stations and graded range of operator units,
and the system's openness.
A range of freely programmable automation stations
There are two series of automation stations in the range: compactand modular.The
main difference between the two categories is the flexibility of their data point mix.
This strategy ensures optimum adaptability to customer requirements and to the
building services plant.

The room unit: the key to individual comfort
The DESIGO RXC range of room units covers the widely differing needs of room
occupants. The designers of these stylish room units also took account of ergonomic
factors.
The HVAC system, lighting and blinds can be operated in various ways:
In the conventional manner, with standard room units for HVAC and electric switches
to control lighting and blinds
Examples from the QAX3 range ... and the QAX50 range
The integrated room unit combines the operation of HVAC, lighting and blinds in a
single device. The keypad can be configured with the combination of buttons and
switches best suited to the application.
Applications
A range of predefined, downloadable applications makes DESIGO RXC highly
versatile. The standard applications are available in a library covering various fields of
application such as fan-coil units, radiators, chilled ceilings and integrated applications
incorporating lighting and blinds.
Due to the fact that these applications are largely pre-defined, engineering is reduced
to the definition of a small number of parameters.
Example of integrated applications

The management level: DESIGO INSIGHT OPEN
The management level is responsible for monitoring the processes in the building and
for providing a simple means of operation and fine-tuning designed to optimize
operation.
With integration at this level, the third-party system is connected directly to the
management station and its database systems. In terms of functions, the emphasis is
on alarm handling, reporting, long-term data acquisition, operation and monitoring of
the system concerned. Integration into the management level primarily involves stand-
alone subsystems or island systems with large volumes of data.
As a native BACnet management station, DESIGO INSIGHT integrates third-party
devices and systems in compliance with BACnet 135-2001 directly and without
additional interface conversion.
The functional scope of the overall system is based on the overlapping function of
DESIGO INSIGHT, operating here as a BACnet client and the connected third-party
system (operating as a BACnet server). It can be determined by comparing the PICS.

The automation level: PX-OPEN
The integration of third-party or field-bus systems at the automation level permits
flexible re-processing of the third-party system data and enables functions to be linked
quickly, directly and reliably to the distributed automation processes in the building
(peer-to-peer communication). Third-party systems are fully integrated into the higher-
level control strategies while retaining complete autonomy.
Integration into the automation level is an economical solution, and is used primarily for
control systems and open field-bus networks with up to 2000 data points.
The integration platform, PX-OPEN, is a fully valid stand-alone automation station for
the connection of third-party devices, systems and field-bus networks to the BACnet
automation bus. As a freely programmable BACnet controller, it processes the third-
party system data, maps it to BACnet and provides peer-to-peer communication with
other automation stations.
The bi-directional exchange of data for up to 2000 information points is event-driven,
i.e. the systems only exchange information if the data point changes.

The field level: I/O-OPEN
A small number of distributed third-party devices can be connected quickly and
economically at the field level and further processed in the automation system.
The devices are integrated either via digital/analog inputs and outputs, or with a
microprocessor-based interface module.
The microprocessor-based I/O modules (I/O-OPEN) connect selected third-party
devices via RS232 or RS485 to the distributed input/output field bus of the automation
station.
The I/O-OPEN module maps the third-party data points on the module bus (P-bus) to a
number of virtual standard modules. The automation station communicates with these
virtual modules as if they were actually present. Various types of I/O-OPEN modules
are used, depending on the communication protocol utilized by the field devices and
compact systems.

Programming with D-MAP
The D-MAP programming language (= DESIGO Modular Application Programming) for
DESIGO PX ensures efficient programming and parameter setting for building services
plant. The programming language, D-MAP, is optimized for building services
applications. The control strategies required for and best suited to efficient operation
are implemented using graphics-based data flow programming.
Efficient engineering with blocks and compounds
The project-specific HVAC applications are configured, programmed, commissioned
and maintained using the CFC Editor in PX Design. The CFC Editor is a graphics editor
based on blocks and data flow techniques. Predefined and tested application programs
are assembled to create compound structures (referred to simply as compounds), and
these are then made available in the libraries.

Creating the CFC chart with the CFC Editor
Features of D-MAP programming:
The elements of D-MAP programming are blocks and "compounds" (compound
functional units). These are stored in libraries.
To create a D-MAP program, the blocks and compounds which provide the required
functions are combined in the CFC Editor. This process involves creating instances
(of blocks) or copies (of compounds) from the libraries.
The flow of data between blocks is programmed by interconnecting the "pins"
(inputs and outputs) of various blocks.
Libraries
PX Design incorporates comprehensive libraries in which the functions, function blocks
and compounds are stored. The libraries contain images of actual plant, aggregates
and components in a structure which can be used equally for design engineering,
control, operation and monitoring and display.

A number of PX automation stations and RXC room controllers can be interconnected via BACnet over
LON and, depending on the size of the system, monitored and operated with one or more network-
compatible PXM20 operator units. For remote operation, the system can be extended to include Weboperation with the PX-WEB software. With the Web operating software, building operators have access to
all the functions of the PXM20 from anywhere and at any time. In the event of a fault, alarms can be
transmitted via SMS or e-mail for added reliability.

The DESIGO INSIGHT management station lets you get the most out of your plant.
The plant is operated using highly informative, animated graphics. Optimum building
operation is ensured by use of scheduler programs that can be operated centrally, a
clear alarm handling system and a wide range of other options. The DESIGO system
can be embedded in existing IT Ethernet/LAN infrastructures.

Remote sites can be operated and monitored by telephone from a DESIGO INSIGHT
management station. In the event of a fault, the automation stations establish a
connection with the higher-level management station to alert the user to the problem.
The user can then navigate to the relevant graphical display.
