The DESIGO building automation and control 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 scaleable system covers everything from small, standalone 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.

Distinguishing features of the DESIGO system Open to integration The open system architecture is widely supported, making it possible to integrate thirdparty 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: the BACnet standard, both for communication between the management and automation stations, and for communication from one automation station to another, and LONMARK for room automation. DESIGO also supports components and systems with interfaces such as OPC, Ethernet, LON, EIB, Modbus and M-bus.

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.

Innovative Web access With PX Web operation, and DESIGO WEB, the DESIGO system 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 other HTML reports, irrespective of the location of the user. In this way, those responsible for the system can be kept up to date at all times.

The scaleable system: for all projects from small to large DESIGO is the perfect choice for all projects, no matter how small or large. An extensive, modular range of automation stations, a variety of operator units, modular application software and a flat system topology all combine to ensure low start-up costs for small systems. At the same time these systems can be extended at any time, and expanded into comprehensive large-scale systems.

Economical in every phase The installation of highly automated building services plant is increasingly taken for granted. Due to technological advances and improved project handling, costs per data point are falling steadily. A prime concern in the field of building services, however, is the overall cost over the life cycle of the plant. With sensible start-up costs, efficient and cost-effective support during operation, plus flexible service options, the DESIGO building automation and control system is the right choice for the economy-minded building operator.

DESIGO system topologies The 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. Within the network, the DESIGO building automation and control system uses manufacturer-neutral standard protocols for communications, specifically BACnet for the management level and automation level, and LONMARK for the field level.

System design for small to medium-sized buildings A number of PX automation stations and RXC room controllers can be interconnected without difficulty via BACnet over LON and, depending on the size of the system, monitored and operated with one or more graphics-based, network-compatible PXM20 operator units. For remote operation, the system can be extended to include Web operation with the PX-WEB software. This Web solution presents the resident engineer with all the functions of the PXM20 operator unit whenever required, with the advantage of access from home, for example. In the event of a fault, alarm notification can be arranged via SMS or e-mail. 01623

DESIGO RXC

System design for medium-sized to large building complexes The DESIGO INSIGHT management station lets you get the most out of your plant. Even in systems with a hundred data points or fewer, it proves its worth. The plant is operated using highly informative, animated graphics. Optimum building operation is ensured with scheduler programs that can be centrally operated, a clear, consolidated alarm handling system and a wide range of other options. The DESIGO system can be embedded without difficulty in existing IT Ethernet/LAN infrastructures. Naturally, DESIGO can be expanded into a multi-user system. Remote operation via the Web should also be mentioned here: this is an option which can be implemented with DESIGO WEB and the PX-WEB solution for Web operation. E-mail

Distributed buildings Up to 1,000 remote sites can be operated and monitored by telephone from a DESIGO INSIGHT management station. In the event of a fault, the automation stations automatically call the higher-level management station, which displays the fault to the user in a "pop-up" window. The user simply clicks a button to navigate to the associated graphics. In the case of the "life-safety" feature, the modem connections are checked at regular intervals. For remote access, connections can be established not only by modem, but also via Ethernet/LAN. The management station can be connected anywhere on the in-house LAN, from where it has access to the automation system via the router. E-mail

System functions Trend/History Fully integrated trend data processing allows effortless evaluation and analysis of realtime (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. This means that nothing now stands in the way of displaying BACnet data from other manufacturers. Data for trend analysis can be logged in a variety of different ways: Trend logging options: • Continuous logging

• Polling

• Single run

• COV polling (Change of Value)

• Transient run

• Event-driven polling

With the Online Trend option, individual data points are registered on a COV basis or through polling, and displayed immediately. The values are stored temporarily, in order to observe transient response patterns, for example. Features of Online Trend:

Offline trend

• Real-time display of process data

• COV-driven data

• Short time periods (seconds, minutes, hours)

• Temporary data, not normally stored.

Offline Trend by contrast, does not depend on a permanent connection between the automation station and operator unit, because the values in the automation station can be stored temporarily for retrieval on the operator unit as needed.

11/48

Features of Offline Trend: • Offline data display, no connection required

• Cyclical acquisition of data

• Longer periods of time (days, months)

• Data acquisition in the automation system. The data is uploaded periodically to a database at the management level.

Graphs can be displayed on both the PXM20 operator unit and the management station, in the latter case as 2d or 3d graphs and in color.

Alarm management One of the most important features of a building automation and control system is the ability to generate alarms automatically in the event of faults; these faults may occur in the HVAC and other systems 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. In this context, DESIGO makes full use of the BACnet standard as a basis, and supports the following three types of alarm: • Simple Alarms (for alarms not requiring user interaction) • Basic Alarms (for alarms requiring acknowledgement) • Extended Alarms (for alarms requiring acknowledgement and reset) DESIGO also supports the 256 alarm priority levels of the BACnet standard, which can, for example, be consolidated at the management station into ten priority levels. Alarm messages

When an alarm occurs, it is automatically detected, registered and transferred to operator units such as the PXM20, to PX Web for Web operation or to the DESIGO INSIGHT management station. Informative alarm messages are also transmitted to remote devices such as mobile phones, fax machines, printers, PCs and Web browsers, via SMS and e-mail. Clear alarm lists provide a view of all pending and timestamped alarms at a glance, and permit straightforward processing. Pop-up windows and audible and visual signals alert operators to incoming and pending alarms.

Alarm routing

Alarms are transferred on the basis of time, priority and/or plant type with an outstandingly powerful alarm routing system at the management station. In this way, important messages reach their destination 24 hours a day throughout the year, 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. Ventilation, heating, air conditioning, lighting, door locks etc, are controlled on the basis of opening times and working hours in buildings such as offices, banks, restaurants, department stores and schools. 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. Saving energy

The ideal scheduler programs help save energy and increase the service life of the plant.

Increasing the service life of plant

Research has shown that scheduler programs are rarely used to best effect to save energy and extend the service life of plant, because the programming operations required are too complex. This is another area where DESIGO excels with its straightforward and exceptionally user-friendly operation.

Standard BACnet functions

DESIGO is based on the worldwide BACnet standard, in which even complex functions such as scheduler programs are standardized. Time-switching operations in the DESIGO building automation and control system are implemented in accordance with this standard, using the BACnet objects "Schedule" and "Calendar". These powerful functions can be operated flexibly, from simple 7-day programs for standard operation from Monday to Sunday, to more sophisticated, recurring exceptions, such as business opening times every second and fourth Saturday in the month. With the standard BACnet functions, even BACnet schedules from third-party manufacturers can now be monitored for the first time via the easy-to-use PXM20 operator unit, the PX Web controller and 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.

13/48

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 read access 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. Freely-definable access rights

Only authorized personnel are granted access to the system via the operator units and the management station. When a user enters a user name and password, the system verifies the associated access rights and enables access to the relevant plant and programs. Read and write access rights can be defined in detail, down to individual information points. These are assigned to one of the seven following access classes. Internal Adaptation Service Administration Expert Standard Customer

Advanced service activities Basic service activities Extended operation Basic operation

In addition to the above, it is possible to enable or disable he 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 Technical designation Unique addressing of all elements is essential for the identification of the plant and the associated elements. In this area DESIGO has introduced an innovation, the "Technical View", which is based on the user's viewpoint. This standardized hierarchically structured view is based on the needs of the users of the plant. Addressing is thus not based on the device-focused viewpoint of the automation stations (e.g. "Controller08/DigitalOutput02"), but on the user's viewpoint, e.g.: Clear-text designation

"Location Kingston/Ventilation, Building 6/Air handling, 3rd floor/Supply air fan/Fan switch".

Fast location of alarms

The hierarchical structure is ideally suited to various types of plant, such as primary plant, room systems and integrated systems, for example. Naturally, clear-text designations are used throughout the system, appearing for example in alarm messages, facilitating fast location of faults.

Communication standards: specifically designed for building services Building automation and control system projects are increasingly engineered without recourse to costly gateway solutions for the exchange of information. With the BACnet open communications protocol, compliant devices can be interconnected at low cost. The worldwide BACnet standard was developed under the auspices of ASHRAE specifically for the needs of building services. BACnet networks provide all subscribers with access to all the data and functions of the connected devices. BACnet and LONMARK

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 PX automation station and another, and between DESIGO PX and DESIGO INSIGHT. DESIGO uses Ethernet/IP, LON or PTP (point-to-point) as the transport medium. At the field level, DESIGO RXC uses LONMARK, the standard ideally suited to the requirements at this level.

15/48

Features of BACnet The open BACnet communications protocol, a worldwide standard, has the following special features: • BACnet supports modern networks such as Ethernet, ARCnet, LONTALK, RS485 and point-to-point connections. • BACnet provides 23 predefined standard objects, including special objects for applications such as trend logging, averaging, alarm distribution, time scheduling and the connection of fire and safety systems, including fire detection systems etc. • BACnet systems offer maximum interoperability with minimum engineering. • BACnet supports decentralized systems with distributed intelligence. • There are no user fees associated with BACnet – anyone can develop and use BACnet solutions.

The management level: DESIGO INSIGHT The clearly structured, modular, object-oriented software of the DESIGO INSIGHT management station is based on Windows standard 32-bit technology. The functional scope and ease of use of the software reduces operating costs and the time required to become familiar with the system, while at the same time increasing operational reliability. The DESIGO INSIGHT applications are available in a basic "Start-feature" package, with other applications available as options: Start-feature package

• Basic shell software via the taskbar: Provides a quick overall view of the system and is used to start whichever user applications are required. • System Configurator: Used to configure the general setup of the DESIGO INSIGHT management station and the associated applications. • Object Viewer: An efficient tool for navigation through the hierarchical tree-structure to all the data points in the system. These points can then be read or manipulated, depending on the access rights of the user concerned. • Time Scheduler: Central programming of all time-controlled building services functions. • Alarm Viewer: Provides a detailed overall view of alarms from between one and 1,000 buildings for the fast location and elimination of faults. • Alarm Router: Flexible transmission of alarms to printers, fax machines, mobile phones and e-mail.

Options

• Plant Viewer: Realistic plant graphics allowing fast, targeted monitoring and operation of the system • Trend Viewer: Convenient analysis of trend data for fine-tuning the operation of plant • Log Viewer: Alarms, errors and user activities are logged in chronological order, and can be displayed for further evaluation, as needed. • Web Access: Provides access to the Web applications "Web Graphics", "Web Alarms", "Web Log" and "Web Reports". • Graphics Builder: Powerful tool for efficient creation of customized plant graphics • Open drivers such as OPC, EIB, LON etc.: For direct integration of OPC, EIB, LON and other interfaces into the management station. • Various alarm receivers Pagers / SMS, Fax and e-mail

Shell and 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 systems with several remote installations, it is possible to switch from one plant to another via the taskbar, subject, here too, 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.

17/48

Background functions in DESIGO INSIGHT:

• Life Check feature for checking the connection to the automation systems • Alarm upload after system start • Check for correct running of the other applications of DESIGO INSIGHT V2

• Time synchronization between management station and site. DESIGO INSIGHT can be configured as the time master for the system • Hard-disk memory capacity check • Database availability check

Plant Viewer Plant Viewer displays the areas of a building and the associated plant in graphical form. The user works interactively with these views to monitor and control the data points throughout the building. Process display

Plant Viewer is based on the Citect process display software supplied by Citect Pty Ltd. Citect is a world leader in the supply of SCADA systems. Numerous windows of different sizes can be displayed simultaneously (overlapping or tiled). Even large graphics, such as floor plans etc. can be accommodated, and the freely definable page size makes them easy to view. Setpoints, alarms etc. can be manipulated directly in the graphics. The user can modify a value or acknowledge an alarm simply by clicking on the relevant object.

Real-time display

18

Measured values, setpoints, operating modes and alarms are displayed on the screen in real-time, and updated continuously. The form of display is determined in the engineering phase. Changes are indicated either by the object symbol, e.g. through animation or a change in shape or color, or by a change in color, shape, text or movement of the values affected.

Other features of Plant Viewer: • Genuine multitasking with fully dynamic functioning of all active pages • Object-oriented plant monitoring and operation • Freely definable page size option for versatile handling of several pages in the same screen

• Page selection via Page list dialog box, or

• Definition of, and quick access to "Favorite" pages • ToolTips for all dynamic objects, with the option of User, Technical or System Designation • Context-specific information such as text, photos or maintenance information can be added to each dynamic symbol

Alarm management Alarm Viewer The Alarm Viewer application displays alarms by type, and provides the user with helpful information as to the type of action required by the system. 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 is entered in this database and automatically displayed on all other management stations. The processing is different from one management station to another: • Only the management station defined as a destination for the alarm can forward the event and display an alarm window ("pop-up"). • Pop-up windows are configured specifically in the Alarm Router on each management station. • To acknowledge or reset an alarm, a management station must be connected to the site to which the alarm object belongs. 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

19/48

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: • • • • • Criteria for the transfer of alarms

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: • • •

20

Printers Fax machines Pagers Mobile phones E-mail systems

Time (e.g. at night, switch to the printer in the night 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 resident engineer by pager in the case of high priority alarms)

Time Scheduler The Time Scheduler application in DESIGO INSIGHT can be used for central programming of all time-controlled functions in the building services plant, including the individual room control system. Graphics-based operation

The facilities for graphics-based operation of the weekly schedules and exception programs, the user can modify and optimize scheduler programs at any time and without difficulty. Principle functions: • Graphics-based overview and manipulation of all scheduler programs in the system • Easy graphics-based programming of switch times • Programs invoked directly from the plant

• Direct entry of various operating modes (e.g. Comfort, Standby, Energy Hold-Off) • Storage and processing are independent of the management station • Report printed in different display formats

graphics

System Browser view, and overview of daily profiles in the Time Scheduler application

Trend logging 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 easyto-handle tool used to optimize the operation of plant and reduce costs. Activities in Trend Viewer: • Log process values over a period of time

• Monitor current plant conditions

• Track energy consumption

• Plant optimization and fine-tuning

21/48

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 (and even data from the archive) can be displayed simultaneously in separate windows, enabling the user to compare past and current situations.

Drag Drop

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.

Advanced Data Processing (ADP), Consumption Control (CC) ADP and CC are add-on software packages. These add-ons are used for effective storage, archiving and evaluation of process data, and are especially suitable for medium-sized and large projects where there is a requirement for long-term storage and flexible, customized evaluation of data. Process values can be displayed in the form of lists, reports or graphs (trend views). ADP and CC use their own standard database, which is fully independent of the DESIGO INSIGHT offline database.

22

Log Viewer The Log Viewer provides a view of the events and user activities archived in chronological order in the log database. Users thus have access whenever required to all past events. Event Handler

The data logging system is a background service performed by the Event Handler in DESIGO INSIGHT V2, which continuously logs reported events as follows: • Alarm events from the process level such as plant alarms, high priority warnings, frost alarms etc. The alarm is logged when it occurs, and thereafter upon acknowledgement, reset and return to normal. • System events from DESIGO INSIGHT management stations and PX automation stations. Examples are communication problems, 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 two user interfaces of Log Viewer and Alarm Viewer use tables with the same "look and feel" and with a versatile range of options for sorting and filtering.

Functions in Log Viewer:

• Query-configurations can be stored and reused. The status bar displays the current filter and sort status • The Log Viewer display is divided into five

• Columns can be flexibly rearranged, resized or hidden as required • The events logged for a specific object, such as events associated with a given site,

The logged data is stored on a Microsoft SQL server or in an MSDE database. Password protection prevents unauthorized access.

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 if required. The criteria for archiving in DESIGO INSIGHT are as follows: • Automatic archiving at specific time intervals • Automatic archiving based on the volume of data accumulated • Manual archiving initiated by a user command

23/48

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 are defined as part of the DESIGO PX engineering process. The engineering of a user view is relatively time-consuming, but does make it possible to combine a geographical and a plant-based structure, which can be useful in larger projects. • 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 (Site.Device.Object).

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 pane of Object Viewer displays the contents of the currently selected object.

Functions in Object Viewer: • Fast navigation through the building automation and control system • Fast location of objects and alarms • Detailed information on the properties of each object • Display of real-time data from the process. • Modification of setpoints and parameters,

• Modification and definition of object-related text • Find function with wildcarding for quick and direct access to certain objects • Object search in other views by changing view in context-menu

Web Access Web Access is an interface to the building, based on a browser and using integrated Web technology. Web Access can be used for roaming, and for remote access to and control of important building-related information managed by DESIGO INSIGHT.

Home page

Given the now widespread familiarity with Web browsers, even occasional users can access the required data quickly. This cost-effective solution reduces the cost of training, software installation and maintenance. The Web Access software facilitates and encourages the simple distribution of building information to those who need it, and at the point where they need it. Given the modular structure of DESIGO INSIGHT, new and existing DESIGO INSIGHT systems can be upgraded with Web Access at any time. The principles of Web Access can be applied in a building network, over the company intranet and on the Internet. Using technology based on Microsoft Active Server Pages, Web pages work together with DESIGO INSIGHT to exchange data between the browser and the system. There are two methods of data exchange: • Via the Citect interface, for the exchange of dynamic data and for alarm handling • Via ODBC queries to the SQL databases 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 dowloading of Active-X or similar scripts.

26

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. Web Access provides access to the system via a browser. This maintains the familiar format based on the successful operability guidelines of DESIGO INSIGHT. • Index Page is the equivalent of the familiar "Home Page". From here, the user can obtain a quick overall view of the system, or start navigating around the site. • Graphics-based view of 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. • Alarms from the DESIGO INSIGHT database are collated in tables. "Sort" and "Filter" procedures can be predefined or carried out 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. • Reports can 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 information option provides an overview of the Read and Write privileges of a logged-in user.

Automation stations: the compact series The compact series of automation stations is ideal for all control and monitoring activities in distributed HVAC systems. The compact-series automation stations have built-in I/O terminals and can be used in packaged-unit (e.g. AHU) control panels and standard installations, even where space is very limited. All compact automation stations are freely programmable and incorporate the full range of system functions. The operator units are easily connected using standard cables. In addition, up to five QAX… room units can be linked via a two-wire connection directly to the PPS2 interface.

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 bar and can be interconnected in application-specific configurations. 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. Third-party systems and components can be integrated via the "intelligent" PTM… I/O modules. 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. Up to 128 modules can be connected to the modular automation stations, depending on the basic type selected and the total number of load units.

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 new programming language, D-MAP, based on standard IEC1131, is optimized for building services. 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 block programming and data flow techniques (see also "Commissioning and engineering with DESIGO TOOLSET"). CFC chart ntiate Insta

Creating the CFC chart with the CFC Editor

The characteristic features of D-MAP programming are as follows: • •



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 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.

Made-to-measure operator units The various operator units in the DESIGO PX range more than satisfy all the various requirements in terms of location and function.

PXM20 operator unit The PXM20 operator unit allows uniform operation of various building services at the automation level. The operator unit incorporates buttons for operation, and a highresolution display panel for displays in graphics-based and text format. The PXM20 can be used either locally or for remote access to all the plant connected in a network. The handheld operator unit can either be installed in a control panel or plugged into an automation station.

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 the building 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 (LONMARK over 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.

37/48

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. 70225

System Design (with Project Management and Solution Browser) System Design includes project management functions such as the setting up and archiving of projects and the storage and relocation of project data for the commissioning phase. System Design is used to structure and specify plant and partial plant. From the library of pre-programmed and tested solutions, the engineer can use the Solution Browser to select and configure the solution best suited to customer requirements. System Design is also used to define the network topology, and to design any room management solutions and the integration of third-party systems. The number of automation stations required for the partial plant is calculated automatically. This is followed by the addressing of the data points.

PX Design PX Design is the graphics programming and configuration tool for DESIGO PX. PX Design supports the downloading of the application programs and the commissioning of the system.

The compounds, which themselves contain function blocks, represent tested solutions, selected via the Solution Browser. Where objects have been added or removed in System Design, it may be necessary to use PX Design to modify the compounds accordingly.

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