The DESIGO building automation andcontrol system: the powerful, open system

DESIGO is a new and up-to-date family of freely programmable

management and automation stations for the full spectrum of today's

building services applications. With system functions such as alarm

management, time scheduling, and trend logging, combined with

sophisticated control functions, DESIGO is a highly versatile asset in

a building. Innovative Web technology, open databases and open

communications make DESIGO a financially wise investment in the

future.

The scalable system: for all projects from small to large

With its graded range of automation stations, room controllers and operator units,

DESIGO is ideally suited to projects of all sizes and for all types of building. A flat

system topology permits low-cost entry with small systems which can be extended and

expanded when required.

Open to integration

DESIGO is consistent in its support of open communications, making it easy to connect

a wide variety of building services equipment on the basis of standard open data

interfaces:

BACnet for the automation level and management level network

LON and KNX (EIB) for the networking of the room automation system and

distributed secondary processes

M bus, Modbus, OPC and other interfaces for universal connection of third-party

devices and systems

Easy to operate

DESIGO INSIGHT uses life-like graphics to portray complex issues simply.

Typical aspects of air conditioning, such as psychrometric charts and heating curves, or

control routines such as load shedding and mains recovery are illustrated with clarity.

The interfaces, designed in accordance with ergonomic principles, permit optimum use

of the system and can be mastered quickly by operators. Access is also available via

the intranet and Internet.

Long-term investment protection and economy at every stage

DESIGO places emphasis on long-term investment protection by focusing consistently

on compatibility. DESIGO integrates today's automation systems seamlessly into

tomorrow's world. Changes in use, system expansion and retrofit projects can all be

handled in gradual stages.

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, operation and monitoring of the

primary plant. By use of PX-WEB, the

automation system can be operated via a

Web client.

The I/O modules, which provide the

interface to the devices at the field level, the

sensors and actuators.

DESIGO RX, 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.

System functions

Operation and monitoring

Operators of the DESIGO building automation and control system have a versatile

range of equipment at their disposal, offering convenient access to the system and the

plant.

Operator station

The DESIGO INSIGHT management station is a powerful and user-friendly interface for

monitoring of the overall system. User access to DESIGO INSIGHT can be matched to the

level of responsibility of a given user of the building automation and control system.

DESIGO INSIGHT Web Access allows access to the management level using Web

technology.

The PX-WEB software uses Web technology to map all plant and system information from the

automation level to a standard Web browser.

Room operator unit

With the QAX product range, room users can view and operate the setpoints and measuredvalues used for individual room control.

Operation in the control panel

The user-friendly, graphics-based PXM10 operator unit allows full local operation of the

automation stations.

The network-compatible graphics-based PXM20 operator unit presents all plant and system

information in an easy-to-understand format, with a plain-text commentary.

Manual operation

The DESIGO I/O modules in the PTM product range include facilities for

manual/emergency operation of plant and for the display of operating states. The PXC36-S compact automation station incorporates slide switches which can be

configured for manual operation or as freely-assignable outputs.

Trend/History

Fully integrated trend data processing allows effortless evaluation and analysis of real-

time (online) data and (offline) historical data. The trend feature simplifies the

monitoring and fine-tuning of the plant. In the DESIGO system this feature is

implemented in the form of trend log objects, 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 for a defined 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 connectionbetween the automation station and the operator unit, since the values in the

automation station can be stored temporarily for retrieval on the operator unit as

needed.

Offline trend

Features of Online Trend: Features of Offline Trend:

Real-time display of process data

Can be based on changes in the value of a

data point (COVs) or on periodic sampling

Offline data display, no connection required

Longer periods of time (day, month)

Data acquisition in the automation system

The data is uploaded to the management

level at regular intervals or as needed

8/52

Alarm management

One of the most important features of a building automation and control system is the

ability to generate alarms automatically in response to faults which may occur 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 alarm (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 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 visual signals.

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, 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.

By use of standard BACnet functions, the BACnet scheduler programs can be operatedsystem-wide from the user-friendly operator units PXM20 and PX-WEB and from the

DESIGO INSIGHT management station.

Scheduler program on PXM20 operator unit and 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.

10/52

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, right down to individual information points.

Freely-definable accessrights

The following classes of access are supported in the DESIGO system:Users supported system-wide

Internal

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, so simplifying cooperation between the

various user groups.

10


11/52

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 thedata and functions of the connected devices.

For the exchange of information among its own system components, DESIGO uses

three standard protocols, recognized worldwide: BACnet, LONMARKand KNX S-mode

(EIB). 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.

BACnet, LONMARK andKNX S-mode (EIB)

DESIGO uses Ethernet/IP, LonTalk or PTP (point-to-point, modem or null-modem) as

the transport medium. At the room automation level, DESIGO RX communicates in

accordance with the LONMARKstandard or KNX S-mode (EIB).

In the case of BACnet/IP over Ethernet, the standard transport protocol UDP is used,

since BACnet already provides adequate mechanisms for the control of data transport.

Like TCP, UDP is a transport protocol, but unlike TCP, it is a wireless protocol.

BACnet/IP

DESIGO is a native BACnet system, and as such, every device incorporates BACnet

as a basic, integrated and permanently available feature. The management stations

and automation stations are all implemented as full BACnet nodes. BACnet is

integrated directly without the need for any special conversion of data. BACnet

communications can be generated without additional hardware or services.

Native BACnet

DESIGO is compatible with the communications resources of the legacy automation

systems UNIGYR, VISONIK, INTEGRAL and SIMATIC S7 and allows their seamlessintegration. Changes in use, system expansion and retrofit projects can all be handled

in gradual stages.

Alarm Viewer

The Alarm Viewer application displays alarms by type, and provides the user with

helpful information as to the system intervention required. With its extensive filter and

search functions, Alarm Viewer facilitates fast and well-targeted access to the required

information.

In larger systems with more than one management station, all management stations

access the same alarm database. An alarm for any given management station isentered in this database and automatically displayed on all other management stations.

Functions in Alarm Viewer:

View, acknowledge and reset single or

multiple alarms.

Display the associated alarm property sheet

with detailed data point information.

Read associated alarm help text with

operating instructions or additional

information in text form

Object-oriented navigation to other

applications, such as Plant Viewer and

Log Viewer

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 defined.

The appearance of the pop-up window can be varied for each alarm category. From

this window, the user can invoke helpful instructions about the required response to the

alarm, or jump directly to other applications such as Plant Viewer or Alarm Viewer.

16


17/52

Alarm Router

The Alarm Router application is a highly effective feature of building automation and

control. 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 schedules and exceptions (e.g. at night, switch to the printer in the securityguard'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 resident engineer by pager in the case of high

priority alarms)

17


18/52

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 which can be used to optimize the operation of plant and reduce costs.

Activities in Trend Viewer:

Process values and measured values

logged over a period of time

Minimum and maximum values retained in

graphs irrespective of time range

Monitoring of current plant conditions

Plant optimization and fine-tuning

Response times appropriate for the support

of large trend databases

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

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

enabling the user to compare past and current situations.

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 real-time 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 invoked at a later date. Online trend data is

continuously logged and stored in the trend database.

18


19/52

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 ViewThe technical view is the plant-based

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 are defined as

part of the DESIGO PX engineering process.

System ViewThe system view is a standard hierarchical

view, representing the topology of the

BACnet network, whereby a site contains

devices and each device contains objects.

20


21/52

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 communication failures, selection procedures, 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 is

based 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

particular category 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).

Logging of changes in the project

configuration Parameter modification feature includes

original parameter value

The logged data is stored on a Microsoft SQL server or in an MSDE database, and

protected by password.

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 if

required. Data is archived in DESIGO INSIGHT automatically on the basis of time orquantity of data accumulated, or manually by the user.

Log and trend data archiving

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

The DESIGO PX automation level

The most striking features of DESIGO PX are the consistent openness of the system

and the scalability of the system with its freely programmable automation stations and

operator units. DESIGO PX reliably meets all expectations associated with the control

and monitoring of building services.

A family of freely programmable automation stationsWith its range of compact and modularautomation stations, DESIGO PX can be

perfectly matched both to the preferences of the customer and to the building services

plant. The two categories of automation station are equal in respect of their control

functions and both are freely programmable. Supported by graphics-based

programming, the processing functions are fast, accurate and field-proven. In addition,

important system functions such as fine-tuning programs, time schedules, local trend

storage and recovery after a power failure are implemented in the automation stations

themselves. The plant operator can display all the required information on the LCD

display panel of the PXM10 and PXM20 operator units.

A range of graded operator units

Room users and building operators benefit from a comprehensive range of operator

units which can be used for targeted modification of room conditions or of the whole

plant.

The compact automation stations

The mounting technique and fixed configuration of integrated I/Os in the compact

series automation stations make them ideal for control of small and distributed plant.

The I/Os in these automation stations can be adapted to various types of signal.

The automation stations are installed directly in the control panel. The operator units

are connected to the BACnet automation bus or via the PPS bus or Tool/HMI port.

The modular automation stations

The modularseries automation stations with their flexible I/O configuration are

primarily used for the control and monitoring of larger items of plant. The complete

range of input/output modules, for signaling, measuring, counting, switching and

positioning, supports all common types of signal. The I/O modules with local manual

controls on the module housing provide the plant operator with simple manual

operation of the plant directly in the control panel. This local manual control isautomatically transmitted as a remote/local signal to the automation station and

associated operator units. In an emergency, they operate independently of the

automation station, providing stand-alone emergency operation.

Where necessary, the modular automation station can be fitted with an extension

module for direct connection of a modem to allow remote management and alarm

handling in conjunction with DESIGO INSIGHT or PX-WEB.

The field level: the DESIGO I/O modules

The DESIGO I/O modules represent the interface to the devices at the field level, the

sensors and actuators. 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 signaling, measurement, counting,

switching and positioning. The modular system is optimized for installation in control

panels.

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 integrated isolating-terminals facilitate the hardware test carried out during

commissioning.

With DESIGO I/O OPEN, third-party systems and components (e.g. pumps, M-bus

meters, packaged air conditioning units and VSDs) can be integrated via the PTM5

"intelligent" I/O modules. When pumps are connected, for example, access to the

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

and status codes, delivery head, delivery and speed.

For the user, the advantages of the DESIGO I/O modules are as follows:

Integrated isolating-terminal feature

Integrated manual controls (optional)

Optimized for HVAC actuators and sensors

Optimized for installation in the control panel

Third-party system integration with DESIGO

The management level: INSIGHT OPEN

INSIGHT OPEN is a modern integration platform for direct connection to the

management level which uses vendor-neutral visualization systems based on SCADA

technology. SCADA (Supervisory Control and Data Acquisition) systems are software

products from the field of industrial automation, and can be used to connect various

automation systems using a variety of device drivers.

SCADA technology

SCADA technology is ideal for connecting stand-alone third-party systems or openautomation buses and field buses, where the emphasis is on operation and display

rather than on reliable cross-disciplinary interconnection. Vertical connections are

implemented with communication cards or system-specific interfaces plugged directly

into a management system PC. INSIGHT OPEN makes use of the technological

potential of Citect, a leading SCADA system supplied by Citect Pty Ltd. Australia.

INSIGHT OPEN is an adjunct to the DESIGO INSIGHT management station and

provides the following functions for the integrated third-party system or device:

Functions in INSIGHT OPEN:

Graphical operation of the plant and the

process

Alarm display and operation

Dynamic trend curves and long-term data

storage

Operation via data point topology in

Object Viewer

Log book and message archiving

Alarm routing to message receivers

Access protection

In networks, INSIGHT OPEN runs on Windows 2000 or Windows XP.

INSIGHT OPEN provides an OPC client (OLE for process control) for the connection of

third-party systems. This supports the specifications of Data Access Version 1.0a and

Version 2.0.

As a consequence, INSIGHT OPEN is an integral component of the process control

system and subject to the same high expectations in respect of reliability and minimum

downtime.

The process values transferred from third-party systems to the DESIGO INSIGHT

management station are mapped as SCADA process variables, or "variable tags".

Special tags are used for alarm and trend variables:

Alarm tag, alarm process variable

Trend tag, trend process variable

Unlike the data points in the building automation and control system, the process

variables (tags) each contain one item of information only. Alarms and trend logs are

SCADA objects which are generated by and calculated in the I/O server.

The automation level: PX OPEN

The native BACnet automation station DESIGO PX OPEN is a multifunctional

integration platform used to connect third-party automation stations and open field-bus

networks to the BACnet network.

PX OPEN is a family of various types of device:

PX LON for the connection of LON devices, LON networks and the DESIGO RXC

room automation system

PX Modbus, PX M-bus and PX SCL for the connection of Modbus, M-bus or simple

ASCII protocols for RS232 or RS485 (free SCL programming)

PX KNX S-mode for the connection of EIB devices, EIB networks and the DESIGO

RXB room automation system

The data points of the third-party are mapped to input/output functions in BACnet and

are then available as fully communicating data points for further processing and further

connection, e.g. for:

Alarm handling and prioritization

Override control, priority control and commands for central operation

Grouping

Time schedules

Trend logging

PX OPEN integrates up to 2000 items of information per device. The bi-directional

exchange of data is event-driven, i.e. the systems only exchange information if the data

point changes. Peer-to-peer communication can be implemented without difficulty in the

BACnet network

The PX OPEN integration stations are positioned in a flexible configuration in the

BACnet network and can be operated via the local LCD operator units.

"Simple" protocols based on ASCII strings can be connected directly to PX OPEN by

use of SCL (Structured Control Language) in conjunction with a freely programmable

RS232 or RS485 port.

microprocessor-based interface modules.

The microprocessor-based I/O OPEN modules 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.

Examples of vendor-specific protocols:

M-bus meters

Pumps: Grundfos, Wilo

Packaged air conditioning units: MENERGA

Variable speed drives: Siemens SED2

DESIGO tools and software blocks

Professional software tools and a wide range of proven application blocks are available

for engineering and processing the automation stations. The programming language D-

MAP is optimized for building services applications.

DESIGO tools

The DESIGO tools suite consists of the following components:

Management of project data, creation of system topology and selection of

automation stations (System Design or XWORKS Manager)

Programming and commissioning (PX Design)

Commissioning of the BACnet routers (Router Design)

DESIGO tools include project management functions such as the setting up and

archiving of projects and the storage and relocation of project data for the

commissioning phase. The tools are also used to define the network topology, and to

design room automation systems and the integration of third-party systems.

PX Design consists of tools which can be used in conjunction with the block library forthe programming of individual solutions, and for parameter setting and commissioning.

The CFC (Continuous Function Chart) Editor is used as a basis for this work.

Router Design is used to configure the BACnet routers in the system.

Designed for technical work on customer projects, the user-friendly DESIGO software

utilities are easy to use. They include planning, configuration, final adjustment and

commissioning of the automation station with the associated program. A variety of

report functions are available for documentation purposes.

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. 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

The basic elements of D-MAP programming are blocks and "compounds"

(compound functional units). These are stored in libraries.

Features of D-MAPprogramming:

To create a D-MAP program, the blocks and compounds for the required functions

are put together 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" (inputsand 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.

Energy management

Energy management with CAFM solutions

The ever-increasing integration of various disciplines in buildings continuously places

new demands on building automation and control systems, which have now become

the main source of data for the economical running of buildings. A building automation

and control system is indispensable for efficient and cost-effective building

management, because it holds all the technical data from the building, and this data

forms the basis for further processing in other management systems.

Facilities management today places prime emphasis on user comfort and the

minimization of operating costs. To meet demands in both these areas satisfactorily,

additional systems are required, which build upon the existing building automation and

control system.

For efficient and economical facilities management, we offer our own CAFM solutions,

CC (Consumption Control) for energy management and ADP (Advanced Data

Processing) for financial management of the plant. Our applications will fit seamlessly

into your system topology and assist you in the running of your building(s).

Supplementing these two packages, EMC (Energy Monitoring and Controlling), an

innovative Web-based software solution, is also available.

Financial plant management Advanced Data Processing ADP

The ADP application analyses the plant data from your building (measured values,

control variables, messages etc.) and collates this data to produce meaningful reports.

Any relevant data point from the building automation and control system can be

logged for analysis purposes. Based on this data, further measures for optimization of

the plant can be undertaken and monitored.

Analysis of plant data from the building:

Analysis of ambient conditions Identification of scope for optimization

Analysis of processes within the building automation and control system

Verification of the building automation and control process

A number of quite simple optimization measures can be undertaken, with a consequent

reduction in costs, provided that the areas where potential savings can be made have

been recognized. For example, if ADP is used to check the load patterns of particular

groups of energy consumers over a certain period of time, it will become very clear

where savings could be made through re-organization.

Consumption and energy management Consumption Control CC

The CC application produces meaningful reports from meter values. CC shows where

there is need for intervention, and where it is worth investing money in measures to

save energy. A comprehensive tool for monitoring and financial management of energy

consumption, CC makes energy consumption transparently clear and highlights

problem areas. It also lets you distribute costs and consumption values to cost centers,

premises, profit centers etc.

It is only possible to implement energy-saving measures successfully if it is clear where

there is a need for action. The energy signature of a building is an effective tool for

highlighting problem areas in a building or faults in the building services plant. This

energy report shows the relationship between the weekly consumption of heatingenergy and the weekly average outside temperature. In the example, deviations from

the defined setpoint area point to infiltration problems (a "leaky" building).

Example: Energy signature

EMC: Energy Monitoring & Controlling (eAdvantage)

As our first e-service solution, EMC offers you a comprehensive application for

Web-based energy management.

The EMC service module will help you:

To monitor and check your energy and building running costs

To identify potential areas for optimization

To improve quality and performance in the running of your building

Based directly on the consumption data you enter, you will receive regular, informative

reports on the consumption of energy and media, and on emissions.
