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.

With the Online Trendoption, individual data points are registered on a COV basis or

through polling, and displayed immediately. The values are stored temporarily to allow

the analysis of transient response patterns, for example.

Online trend

The Offline Trend option by contrast, does not depend on a permanent connection

between the automation station and the operator unit, since the values in theautomation station can be stored temporarily for retrieval on the operator unit as

needed.

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.

10/48

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.

10


11/48

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.

11


12/48

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.

BACnet/IP

The taskbar

The shell is the first application to appear when DESIGO INSIGHT is started. It is

displayed with a taskbar. It provides fast and direct access to all the user applications,

and displays important status information.

In the case of several remote plants, it is possible to switch from one plant to another

via the taskbar, subject to the appropriate access rights. This ensures clear

demarcation lines between the various areas of responsibility and answerability.

The user's entry into the system is simplified by user-specific start-sequences with

preselected programs and plant.

The DESIGO INSIGHT taskbar

The icons on the taskbar provide access to the main user applications:

Plant Viewer the graphical interface to the plant

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.

17


18/48

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)

18


19/48

Trend Viewer

The Trend Viewer application is used to review current process data in real time

(online) and past process data (offline) over a period of time. Trend Viewer is an easy-

to-handle tool used to optimize the operation of plant and reduce costs.

Activities in Trend Viewer:

Log process values and measured valuesover a period of time

Monitor current plant conditions Plant optimization and fine-tuning

Up to ten process values can be displayed in 2D and 3D graphs in a single trend view.

Several trend views can be displayed simultaneously in different, overlapping windows.

Both online and offline data can be displayed simultaneously in separate windows,

enabling the user to compare past and current situations.

Drag

Objects can be dragged from the System Browser and dropped directly into Trend Viewer

Essentially, trend data can be displayed in three different modes:

Online trend logging: Displays process data which is updated whenever a change of

value (COV)occurs, or as the result of a time-based scan

Offline trend logging: Displays past process data which has been uploaded to a

database at the management level.

Archive data: Displays older data which has been moved from the trend database

into archive files

The trend views can be saved and retrieved at a later date. Online trend data is logged

continuously and stored in the trend database.

19


20/48

Object Viewer

Object Viewer helps users of the building automation and control system to navigate

efficiently through the entire structure. The hierarchically organized data objects are

easy to select, view and modify.

Object Viewer supports three different hierarchical views:

Technical View

The technical view is the plant-related standard view associated with the technical

designation.

User View

The user view is based on customer-specific user designations (user addresses).

The address structure and contents is defined during the DESIGO PX engineering

process.

System View

The system view is a standard hierarchical view, representing the topology of the

BACnet network, whereby a site contains devices and each device contains objects.

System Browser

The left pane of Object Viewer contains the System Browser, which displays a

hierarchically structured view of the system (in a tree-structure). The right paneof

Object Viewer displays the contents of the currently selected object.

20


21/48

Functions in Object Viewer:

Fast navigation through the building

automation and control system

Read/Write access levels are supported.

Object Editor: A user-friendly option for

editing all imported objects

21


22/48

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.

22


23/48

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

browser add-ons. Many customer networks inhibit or even forbid the downloading of

Active-X or similar scripts.

User authentication is achieved by integrating Windows network access and the

authorized DESIGO INSIGHT users. Each time a user accesses the system, the

appropriate DESIGO INSIGHT user access rights are automatically assigned to the

Web pages displayed.

Index Pageis the equivalent of the "Home Page". From here, the user can obtain a

quick overall view of the system, or start navigating around the site. Graphics-based viewof the plant at the automation level, including dynamic

updates of status and alarms, and navigation through the hierarchy. Data points can

be operated and alarms can be manipulated directly in the graphics. The pages can

be generated with the standard graphics in Plant Viewer, so retaining the familiar

DESIGO INSIGHT look and feel. No special Web authoring tools are required.

Alarmsfrom the DESIGO INSIGHT database are collated in tables. They can be

sorted, filtered, and predefined, or processed dynamically. Users can process alarms

and receive dynamic feedback from the system.

Log data logged on the management station can be retrieved via a browser. All

activities in the browser are added, with the relevant user name, to the normal

DESIGO INSIGHT entries in the central log database. Reportscan be displayed dynamically and used for data point control. The limited

performance of some handheld Web browsers can be overcome by use of reports.

The User informationoption provides an overview of the Readand Writeprivileges

of a logged-in user.

Features of Web Access (via a Web browser):

Fast access to important user functions

Display and edit plant graphics

Possibility of immediatedisplay and

processing of alarms

Logging in the log database of remote users

and activities for later evaluation in the

browser

Filtering and sorting of data in the alarm and

log databases, for fast access to the

information required

The integration of the DESIGO INSIGHT

access rights into the Windows network

ensures access security based on

predefined access rights

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 compactautomation stations are optimized for HVAC control and monitoring

activities. Their key feature is their fixed configuration of integrated inputs and outputs.

With their compact construction, they can even be installed in control panels where

space is severely restricted.

All compactautomation stations are freely programmable and incorporate the full range

of system functions.

The network-compatible operator units can be connected either via the built-in port or

via the network. In addition, up to five QAX room units can be linked via a two-wire

connection directly to the PPS2 interface.

The field level: the DESIGO I/O modules

The I/O modules provide the interface to the equipment at the field level. The

I/O modules are connected to the automation stations via the P bus and can be

interconnected in application-specific configurations.

A wide range of I/O modules is available, covering detection, measurement, counting,

switching and positioning.

The I/O modules have LEDs to indicate the status of the plant and, depending on type,

some have controls for manual or emergency operation.

The "intelligent" PTM5 I/O modules are used to integrate third-party systems and

components. For example, when pumps are connected, access to the following

information is available: control of operating mode, setpoint adjustment, fault and status

codes, delivery head, delivery and speed.

DESIGO RXC

The DESIGO RXC room automation system provides individual demand-based comfort

for building users in public buildings, offices, schools, hotels, etc.

The DESIGO RXC equipment controls and monitors defined comfort conditions in

rooms and other enclosed spaces. These functions are finely tuned to satisfy specific

requirements in each room or zone. This makes it possible to take account of individual

comfort requirements while simultaneously saving energy.

Easy control of HVAC, lighting and blinds

The modular design of DESIGO RXC makes it possible to combine the operation of

lighting and blinds with the HVAC control system. Using just one operator unit, room

users can adjust all the room functions to suit their requirements.

Stand-alone operation at field level, or integration into thebuilding automation and control system

The devices in the DESIGO RXC range communicate with each other and with other

LONMARK-compatible devices using a standard protocol (LONMARKover LON bus).Seamless integration into the DESIGO building automation and control system makes

available the additional functions of building management.01715

The DESIGO RXC software

Each device is loaded with application software (referred to elsewhere in this section

simply as the "application") which contains the control program for the associated room

or area.

Siemens Building Automation maintains a comprehensive library of applications

covering a wide range of HVAC and electrical applications.

The room controllers

RXC10.1, the controller in a room-style housing:

This controller is a cost-effective combination of a room unit and an HVAC controller.

Compact-series room controllers, RXC20.1, RXC21.1, RXC22.1 and RXC32.1

The input/output configuration and mounting options of these controllers make them

ideal for fan coil applications. The RXC32.1 controller is particularly suitable for

standard single-duct VAV systems. It comes with a built-in volume sensor.

Modular-series room controllers, RXC30/31

The basic units provide flexible control solutions which can be further enhanced with

extension modules (RXC40/41) for lighting and blinds.

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 HVAC applications covered by the basic controllers RXC30.1 and RXC31.1 can be

combined with control of lighting and blinds.

Integration using DESIGO OPEN

DESIGO allows simple and cost-effective integration of third-party systems and

equipment at the management level, automation level and field level.

The modular and open system strategy enables integration to be based on functional

requirements and the economy of the solution.

The internationally recognized levels within the building automation and control systemmodel also provide an important basis for the integration of third-party systems and

equipment.

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.
