5 DESIGO the flexible building automation and control system The DESIGOTM system is a forward-looking family of freely programmable management and automation stations for the full spectrum of building services applications in today's world. 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, powerful databases and open communications make DESIGO a financially wise investment in the future. Scalable from small to large projects with the highest degree of energy efficiency, transparency and optimum operations as well as applications for infrastructure and industry. 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: BACnetTM for the automation level and management level network LonWorks and Konnex (KNX) S-Mode (instabus EIB) to network room automation and decentralized secondary processes M-Bus, Modbus, OPC and other interfaces for universal connection of third-party devices and systems TCP/IP network protocol Highest degree of energy efficiency The tested DESIGO plant applications comply with European standard EN in the highest energy efficiency classes. You can save, for example, up to 30% percent on energy in offices compared to standard systems through the use of proven and predefined energy savings functions. A number of DESIGO room applications are already eu.bac certified. The DESIGO INSIGHT management station uses life-like graphics to portray complex issues in an easy-to-read way. Trend curves are easily evaluated and analyzed on both the PXM20 operator units as well as the management station. Plant operations are simple to optimize in this manner and allow operators to operate the entire building services plants in an energy efficient manner. Protect investment over the entire life-cycle of the building With its flexible range of automation stations, room controllers and operator units, DESIGO is ideally suited to projects of all sizes and for all types of building.

Consistent compatibility protects investment over decades and throughout the entire building life-cycle. DESIGO integrates existing automation systems VISONIK seamlessly and carries them forward into the future. Changes in use, system expansion and retrofit projects can all be handled in gradual stages. 5 / 72

6 DESIGO System topology with VISONIK The DESIGO system can be divided into two levels: Management level Automation level The automation level forms the interface to the field level and includes room automation as well. By virtue of distributed intelligence, each of these levels operates both autonomously and in a network. The principal DESIGO system components: DESIGO INSIGHT 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 automation system for control and for operation and monitoring of primary plants. By use of PX-WEB, the automation system can also be operated via a Web client. The VISONIK automation system as homogeneous part of the DESIGO system. DESIGO TX-I/O and PTM I/O modules, which provide the interface to the devices at the field level, the sensors and actuators. DESIGO RX 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 plants at all levels of the system. DESIGO Overall system topology with VISONIK One of the key benefits of DESIGO is its scope for gradual expansion, from the smallest systems to large, distributed systems. Scalability is illustrated using example topologies in the appendix. Existing VISONIK process devices are homogeneously integrated into the DESIGO system achieving expanded functionality accordingly. 6 / 72

7 Automation level VISONIK The VISONIK process devices available in DESIGO implements control and monitoring functions in existing building automation and control plants. They can be adapted to any control technical requires on a project-by-project basis. Programming is in a free programming language. All VISONIK process devices work per the principle of distributed intelligence. This guarantees operations of building services plant even when part of the system fails. BPS process station BPS process station BPS process stations is suitable for challenging building automation and control system tasks. The process station and controller work in multitasking mode, i.e. multiple tasks are processed in parallel and in real-time. Application programs are created in COLBAS * programming language. * COLBAS, Control Oriented Language for Building Automation Systems BPS process station most important functions Freely programmable measuring, control and monitoring tasks. Process scheduling functions and applications programs. Local data archiving. Connection for local alarm printer. Communication with: Data and communications server DCS. Process and field devices Operating and output devices. Run manual command entries using a POP Card (Personal Operation Process Card), PC or Palm PDA. Display of process value in the BPS LCD display. 7 / 72

8 DESIGO building automation and control with VISONIK Comprehensive functionality uniform operation DESIGO with VISONIK integrates a number technical discipline for a building with a uniform and cross-electrical and mechanical installation system. Uniform operation from a single operator station allows the operator to operate the building at a high degree of comfort and at low operating costs. Systems with special tasks can be integrated above and beyond the areas heating, ventilation, air conditioning, refrigeration and electrical, such as fire and intruder detection system as well as access control and video systems. Expandable over the long term DESIGO with VISONIK connects process stations and individual room controllers from different system generations. This long-term compatibility includes, for example, the process stations from BPS (PRV2) up to NetBPS, compact stations RWI (AEROGYR) as well as the individual room controller product ranges TEC, DESIGO RX and MONOGYR. Flexibility DESIGO with VISONIK offers a multitudes of possibilities for designing the system, topology as: Integrated system. Regionally distributed system. Remote management system. Linked system. Integration system. Remote management DESIGO in remote management integrates different size buildings in regional and cross-regional systems. Dial-up connections (analog, ISDN) or dedicated lines are used. Full monitoring, operating and optimization is possible. Integrate into the network DESIGO INSIGHT and VISONIK management stations with data and communication server DCS allow for flexible integration into networks. This guarantees a high degree of system security and availability. Validation and certification DESIGO with VISONIK was test per EU-GAMP (Good Automated Manufacturing Practice) and is specially well suited for use in the pharmaceutical industry for the FDA (Food and Drug Administration). 8 / 72

9 Decentralized and distributed intelligence The building automation and control system works according to the principle of distributed intelligence. All levels are autonomous and continues to operate independently when communication or a higher system level fails. Important functions are processed similar to the DDC stations or the room automation controllers. DDC stations exchange data peer-to-peer. Emergency operation of the I/O modules ensure secured intervention at the plant under all circumstances. Data and communication server (DCS) The data and communication server (DCS) serves as the link in DESIGO with VISONIK between the automation level and the management level using DESIGO INSIGHT. DESIGO INSIGHT and VISONIK software can be installed on the same server. Task oriented Its client/server architecture of the DCS supports the system environment with numerous, simultaneous services (multitasking operations). And all management tasks are processed in real time. The most important tasks DCS type PLD 10 / Tower Acquiring, processing, storing process data, and preparing for DESIGO INSIGHT. Monitor process data flow and communications connections to DESIGO INSIGHT at the automation level and to the input/output modules. Run superposed system functions, e.g. peak loads or power restoration program. Distributing alarm and fault messages to receivers such as a printer, fax or mobile services. Scalable and powerful DCS type PLD 10 / Rack DCS can be expanded in a flexible manner from small plants with a few hundred data points up to large buildings with multiple tens of thousands of data points. Easy to maintain Integrated programs for self-diagnostics ease early recognition and trouble shooting of technical faults. Maintenance and renovations as well as expansions are possible without interrupting plant operation. New plants are switched on or others taken from the bus for a period, when improved optimization programs are worked in. 9 / 72

10 Communication between system levels System communications is event oriented per the COV (Change Of Value) principle. Process values in the system are only distributed when actual changes (events) occur. This avoids unnecessary load on the bus and achieve a high-level of performance in large systems as well. Process and system data Data points and their parameters serve in building automation and control tasks as information carriers of process and system data. Data points and parameters In the DESIGO system with VISONIK, data points are optimized to certain applications via their parameters. Parameters characterize the multifaceted properties of the data points, as they contain comprehensive integration functions, for example, for limit value supervision, operating hours count and alarm handling or adjustable operating mode for event processing. The point/parameter model from the system allows the user to intervene into complex functions by activating "parameterization". This simplifies operation and improves the overview, creating the flexibility necessary for efficient operation. The settings are made online. The following example illustrate the impact of point-specific parameters act: Limit value supervision Operating hours count Alarm handling Message delays Measured values and meter values are supervised using set or floating limit values with two limit value pairs available. Limit value violations are distributed as fault messages. The parameters of each switch command point can be set for runtime totalizing. For example, for a three-stage switching commend, the times for each switch stage (OFF/Stage 1 3) are totalized. The alarm handling system can incorporate all data points. Important properties such as limit value, alarm priority, alarm text and output device are configured via the parameters. If an alarm occurs, the time-stamp, cause and frequency of the alarm are stored in parameters. The same applies to the user logon acknowledgement. All events are made available for long-term data storage. Message delays prevent unwanted alarms in the case of briefly occurring, transient states. If the fault persists, the alarm is transmitted after expiry of the delay time. With digital input points, the delay time is started, for example, by a change of state (e.g. from "contact open" to "contact closed"). Messages or process reactions are not initiated until the delay time has elapsed, i.e. when the change of state is stable and unambiguous. In the case of digital output points, the evaluation of the feedback signal can be delayed. 10 / 72

11 Virtual data points Virtual data points (i.e. data points without a direct physical connection to I/O modules) are provided for higher-level applications. Their point-specific parameters can be used, for example, for reliable execution of the following tasks: Buffering of calculated values P, PI and PID control functions with setpoint adjustments Room management, with room groups and zones Plant control with start-up monitoring and safety functions such as frost protection System operation All user inputs are entered online, and processed directly by the system. Operator units The user can operate the system with operator units connected directly to the DCS, operator units connected to the automation stations, and from the DESIGO INSIGHT management station. The system allows combined use of operator units of different generations. Multi-user operation In a DESIGO system with VISONIK, up to four DESIGO INSIGHT management stations can be active concurrently. Further local operator units (e.g. terminals) may be used in addition to the above. In a networked system, multi-user operation can be extended by a further four management stations per system. Web operation DESIGO WEB is a genuine Web solution based on Microsoft IIS (Internet Information Server). The programs for operation of the management system are mapped to ASPs (Active Server Pages) in special interfaces optimized for Microsoft Internet Explorer. Access protection Each user has individual access rights (read and write), protected by password. These cover the following categories: Address range, e.g. ranges based on building or type of plant Graduated read/write access to system functions, parameters and password editing options Expiry date for access rights 11 / 72

12 Logging into the system All login and logout operations of each user are logged and saved in the log database. Reporting Individually compiled reports help the user with diagnostics for the entire DESIGO system. Address ranges, time ranges, parameter names and parameter values can be selected freely. The main report types: Status report Fault report Alarm report Maintenance report Room management report Peak load report for switched loads Automatic reports are activated on the basis of time or date, or in response to a specific event, e.g. as a process reaction in the case of a fault in the plant. Data logging Process values which provide important point information can be logged over long periods of time. This data can be used to review the indoor conditions and plant status, to optimize the process and, in the event of a fault, for help with diagnostics. Data security The logged data is stored securely in the DCS and protected from data loss. The DCS provides various applications for the logging of process and system values. 12 / 72

13 Event log The event log records events associated with the system and the process: User login and logout Fault and alarm messages/alarm acknowledgement Status messages from the plant Configuration changes carried out by the user System error messages Maintenance messages Different operator units can be used for the display and reporting of messages. Values log Data series from all kinds of data points and parameters (measured values, positioning values, operating hours, etc.) are recorded in the "values log". The data series are logged at regular intervals (ranging from every minute to every 24 hours) and saved after synchronization. The values are stored in the form of hourly or daily mean, minimum and maximum values. The data series can be evaluated and analyzed in reports and trend graphs, using: DESIGO INSIGHT The supplementary packages ADP (Advanced Data Processing) for analysis of the process, and CC (Consumption Control) for energy management Archiving Logged events and process values are easy to transfer from the DESIGO INSIGHT log database to other data storage media. Reaction programs A building automation and control system must be capable of responding to specific events, such as the tripping of a safety thermostat or the receipt of a time or date flag, by influencing the process in a predefined way. The events which trigger a predefined reaction can occur anywhere in the system. The "reactions" therefore affect the system. Often the result from the cause of multiple reactions, that for their part are the causes of additional reaction triggers. 13 / 72

14 DESIGO I/O modules In current VISONIK systems, the proven DESIGO PTM I/O modules are already installed in the control panel. The new TX-I/O module can be connected in parallel to the BPS (PRV2). DESIGO TX-I/O modules, which provide the interface to the devices at the field level, the sensors and actuators. They communicate with connected DESIGO PX modular automation stations and can be interconnected in application-specific configurations. A space-saving, flexible product range of compact TX-I/O modules is available for signalling, measuring, metering, switching and positioning. The I/O module system is DIN compliant in design and optimized for panel mounting and supports decentralized, remote module installations. The TX-I/O modules have LEDs or optional LCD displays with signal and warning display programs to indicate the state of the plant and can be manually or emergency operated depending on the module type. The integrated isolating-terminals facilitate the hardware test carried out during commissioning.

16 DESIGO with VISONIK: Migration as the bridge to the future The philosophy underpinning migration from VISONIK to DESIGO is based on integrated, phased and cost-effective modifications to the building automation and control system. This approach makes it possible to keep the system technology consistently up to date. This, in turn, extends the life of the system, so that the high cost of replacing the entire system at a later date can be avoided. DESIGO covers all the important system functions of an existing VISONIK system, including operation and monitoring, alarm management, time scheduling and data archiving. The operation and display of the VISONIK automation stations may differ in certain respects. The following DESIGO section refers to the DESIGO PX automation stations. The path to DESIGO DESIGO INSIGHT, the common management station DESIGO INSIGHT is the uniform management station for all existing systems supplied by Siemens Building Technology. The management station also provides the basis for the seamless integration of VISONIK into the DESIGO system. In addition to the latest technology, DESIGO INSIGHT offers customers an extended range of system functions, and the facility to connect to the new DESIGO PX automation stations. The common management station, DESIGO INSIGHT, is the foundation stone for the future. System expansion with DESIGO PX The expansion of existing VISONIK systems will be implemented with DESIGO PX. State-of-the-art technology is assured by the use of open communications standards, BACnet, LonWorks or KNX. Multiple operating modes are available: local, centralized, via Ethernet or the web. The wide range of possibilities offered by integration makes way for the connection of other disciplines. 16 / 72

18 System functions 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. Operation and monitoring Operator station The DESIGO INSIGHT management station is a powerful and user-friendly interface for monitoring of the overall system. Access and alarm management can be modified to the operator s supervisory chain. For example, alarms can be separated based on the user. DESIGO WEB and DESIGO Terminal Service 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 unit The room unit product range. QAX.. offers functionality matched to meet the exact requirements / needs of the user and the appropriate design. Operation in the control panel The user-friendly, graphics-based PXM10 operator unit allows full local operation of the automation stations.

Manual operation The DESIGO TX-I/O modules include facilities for manual/emergency operation of plants 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. DESIGO operating levels 18 / 72

19 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 the form of trend log objects, in compliance with BACnet standard. Trend logging options: Continuous logging. Single run. Logging over a specified period. Sampling options: 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. Trend Viewer on the DESIGO INSIGHT management station and on the PXM20 operator unit Online trend features: Real-time display of process data. Based on changes in the value of a data point (COVs) or on periodic sampling by Trend Viewer (times can be configured). Offline trend features: Offline data display no permanent connection required. Longer periods of time (days,months). Data acquisition in the automation system. The data is uploaded to the management level at regular intervals or as needed. Alarm management One of the most important functions of a building automation and control system are the automatic alarms for faults in the building services plants. 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 alarms with up to 256 alarm priority levels: Basic alarm (for alarms not requiring user interaction). Simple alarms (for alarms requiring acknowledgment). Extended Alarms (alarms requiring acknowledgement and reset). Alarm messages 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 / 72

20 DESIGO INSIGHT further separates alarms in a customized manner so that each user receives only those alarms corresponding to the area of responsibility. 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 with pop-up windows and audible and visual signals. Alarm routing Alarms are transferred on the basis of time, priority and/or plant type, using a truly 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. Alarm messages on the PXM20 operator unit and on the DESIGO INSIGHT management station Scheduler / Calendar One of the basic functions of a building automation and control system is time control of procedures and processes and ensuring energy efficient operation. Scheduler programs ensure that the heating and lighting are switched off automatically at the end of the workday, 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 / increasing the service life of plant 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. Time-switching operations in the DESIGO building automation and control system are implemented per the BACnet standard, using the BACnet objects "Schedule" and "Calendar". The function allows 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 operated system-wide from the user-friendly operator units PXM20 and PX-WEB and from the DESIGO INSIGHT management station. 20 / 72

21 Scheduler program on the DESIGO INSIGHT management station and on the PXM20 operator unit For safety reasons, schedules and calendars are stored in the automation station, so that in the event of a network or PC failure, the automation level can continue to operate autonomously. Access rights Freely-definable 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 this important information. 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 (edit). 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. The following access classes are supported in the DESIGO system: Internal Extended service Basic service Administration Extended operation Standard operation Basic operation Information flow under control Moreover, the Scopes function allows you to freely adapt the amount of information on the management station to meet the needs and competencies of individual users with regard to building area. Customizing the environment to each user ensures clear areas of responsibility, so simplifying cooperation between the various user groups. 21 / 72

22 Communication - Networks Communication standards specially developed for building services technology BACnet, LonWorks and KNX S mode (EIB) DESIGO Terminal Server DESIGO WEB DESIGO Terminal Server DESIGO WEB BACnet certification Connection of legacy systems Compliant devices can be interconnected at low cost using the BACnet (Building Automation and Control network) open communications protocol. 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. For the exchange of information among its own system components, DESIGO uses three standard protocols, recognized worldwide: BACnet, LonWorks and Konnex (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 PXM20 BACnet operator units and DESIGO INSIGHT. DESIGO/IP uses LonTalk or PTP (point-to-point, modem or null-modem) as the transport medium. At the room automation, DESIGO RX communicates per LonWorks standard or KNX S-mode (EIB). DESIGO Terminal Server and DESIGO WEB make optimum use of the advantages of modern IT technology for the benefit of building services. Properly selected and used, they have a significant influence on the ability to fine-tune the running of the building and on the comfort and satisfaction of building users. This reduces maintenance and upkeep costs. DESIGO Terminal Server provides all the functions of the management system in the form of terminal services over the network. These services can be accessed simultaneously by different users in independent sessions. In addition to operation and monitoring programs for the day-to-day operation of the plant, engineering tools are also provided, allowing modification and expansion of the system while it is running. This makes the DESIGO Terminal Server the optimum solution for professional building operators who need unrestricted access to building data via their intranet or extranet, from any location. DESIGO WEB is a genuine Web solution based on Microsoft IIS (Internet Information Server). The programs for operation of the management system are mapped to ASPs (Active Server Pages) in special interfaces optimized for Microsoft Internet Explorer. All DESIGO PX BACnet servers were submitted to the BACnet Interest Group Europe (BIG-EU) for compliance testing on the BACnet standard DIN EN ISO and successfully certified. A well-known testing institution conduced the comprehensive testing. DESIGO PX devices comply with the B-BC profile (BACnet Building Controller) and DESIGO INSIGHT largely comply with the B-OWS profile (BACnet Operator Workstation). DESIGO is compatible with the legacy automation systems UNIGYR, VISONIK, INTEGRAL and SIMATIC S7 and allows their seamless integration. Changes in use, system expansion and retrofit projects can all be handled in gradual stages. 22 / 72

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 or quantity of data accumulated, or manually by the user. Report Viewer The Report Viewer allows the user to select existing report templates to manually start momentary value data acquisition. A report is then generated with the values for the plant data defined in the template at the time the data is recorded (snapshot function). Pre-selected reports can even be automatically executed together with the Reaction Processor. The reports displayed on-screen can be printed or stored as PDFs for documentation purposes. An export to CSV file format allows for additional evaluation of recorded data values in other programs (Microsoft Excel, Microsoft Access) Filters Filter criteria for searches may be entered to display only the data the user desires in the reports (address masks wildcards, by plant, data point type, time, date, etc.). Standard report templates The following standard report templates available with DESIGO INSIGHT: Reports to record alarm and fault states (active, unconfirmed, etc.). Reports to record logbook entries (alarm, system and user events). Reports to record plant states (manual override, maintenance requirement, room measured values, actual values, setpoint settings, etc.). Customized report templates The Report Builder tool creates customized templates for customers requiring their own template reports. The report function with standard report templates is included as part of the basic license; the Report Builder, however, requires a separate license. 32 / 72

33 Create and query reports via Web With the appropriate access rights, a DESIGO WEB client PC user may select existing report templates on the DESIGO INSIGHT computer via the Web Report Viewer and start momentary value recording. The generated report is displayed in DESIGO WEB and can be saved or printed as a PDF file and downloaded from the Web Server to the client computer. Reaction Processor The Reaction Processor is an event program capable of system-wide monitoring of plants and processes for the occurrence of certain criteria (events) such as time, date, changes of values or exceeding limit values. The Reaction Process triggers preconfigured (re) actions when one (or a combination) of the criteria are met. The user can define the entries in the Reaction Processor. Global time scheduler with calendar function DESIGO INSIGHT has a global time scheduler with calendar functions on the system management level to execute reactions at predefined times of the day (time schedule) or on certain days (calendar / date). You can even control plants and devices on the automation level accordingly without time and calendar functions! Primary application for the Reaction Processor Reaction Processor automates a user's routine work. The Reaction Processor includes a global scheduler / calendar program at the management level for plants integrated at the automation level without a timeswitch. Automated control and switching of plants based on events occurring and monitored during operation. Automated start up and routing of reports. Operation and monitoring with Web technology DESIGO WEB and DESIGO Terminal Server make optimum use of the advantages of modern IT technology for the benefit of building services. Properly selected and used, they have a significant influence on the ability to fine-tune the running of the building and on the comfort and satisfaction of building users. They distribute building information to the person who needs it, and in the exact location where it is needed. In addition to flexibility of operation, both solutions contribute substantially to a reduction in the day-to-day costs of modifications, expansion, maintenance and data backup. Both solutions are based on software standards and are therefore compatible with today's IT security strategies (firewalls, Virtual Private Networks (VPN) etc.).
