The DESIGO building automation and control system: the open system

DESIGO is an up-to-date family of freely programmable management and automation stations for the full spectrum of 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, high-performance open databases and open communications make DESIGO a financially wise investment in the future.

The scalable system: for all projects sizes

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 • LONWORKS and KNX S-mode (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.As it moves into the future, the DESIGO system takes both the automation systems of today and the VISONIK, INTEGRAL and SIMATIC S7 systems, and integrates them seamlessly. Changes in use, system expansion and retrofit projects can all be handled in gradual stages.

6 / 76

The DESIGO system topology

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.

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 TX-I/O modules and the PTM-module, 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.

Figure 1 Overall topology of the DESIGO system

One of the key benefits of DESIGO is its scope for gradual expansion, from the smallest systems through to large, distributed systems. Scalability is illustrated by further examples of topologies in the appendix.

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. 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

measured values 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 TX-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.

Figure 3 Trend Viewer on DESIGO INSIGHT management station and PXM20 operator unit

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 to allow the analysis of transient response patterns, for example.

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

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 by Trend Viewer (times can be configured)

• 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

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.

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.

Time schedules 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 time schedules 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 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 time schedules can be operated system-wide from the user-friendly operator units PXM20 and PX-WEB and from the DESIGO INSIGHT management station.

Figure 5 Time schedule 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.

Saving energy and increasing the service life of plant

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.

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 classes of access are supported in the DESIGO system:

• 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.

Freely-definable access rights

Communication networks Communication standards: specifically designed for building services

With the BACnet (Building Automation and Control network) open communications protocol, compliant devices can be interconnected at low cost. The worldwide BACnet standard was developed specifically for the needs of building services, under the auspices of ASHRAE (the American Society of Heating, Refrigerating and Air-Conditioning Engineers). BACnet networks provide all subscribers with access to all the data and functions of the connected devices.

For the exchange of information among its own system components, DESIGO uses three standard protocols, recognized worldwide: BACnet, LONWORKS and 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 BACnet PXM20 operator units and DESIGO INSIGHT.

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 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.

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 the operation and monitoring programs for daily 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.

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.

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.

DESIGO is compatible with the communications resources of 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.

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 is entered 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

Figure 10 Alarm 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.

Figure 11

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:

• Time schedules and exceptions (e.g. at night, switch to the printer in the security guard's office)

• Responsibility for the site (e.g. send a fax to the company responsible for maintaining the air conditioning)

• Urgency of the alarm (e.g. only call resident engineer by pager in the case of high priority alarms)

Figure 12

Criteria for the transfer of alarms

19 / 76

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.

Figure 13 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.

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-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 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.

Technical View User View System View

22 / 76

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:

• 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.

Figure 16

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 with password protection, or exported via SQL..

Event Handler

23 / 76

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 or quantity of data accumulated, or manually by the user.

Report Viewer

Report Viewer allows the user to select an existing report template and utilize it to start the acquisition of momentary data values. A report is then created for the plant data defined in the template. The values shown are a "snapshot" of the data at the time when it was recorded. In conjunction with Reaction Processor application, it is also possible to initiate preselected reports automatically.

For documentation purposes, the on-screen reports can be printed or saved in PDF format. If exported into a CSV file, the logged data values can be evaluated in other programs (e.g. Microsoft Excel or Microsoft Access).

Filter options

In order to display only the data actually required by the user, queries can be based on filter criteria entered by the user (e.g. use of wildcards in the address mask, searches by plant, data point type, time, date etc.).

Search queries can be saved for repeated use.

Standard report templates

The following standard report templates are supplied with DESIGO INSIGHT:

• Reports on alarm and fault states (active, unacknowledged, acknowledged etc.) • Reports on log entries (alarm, system and user events) • Reports on plant states (manual control, maintenance required, measured room

values, actual values, setpoint settings etc.)

Custom reports

Report Builder is an application for customers who need to create their own report templates to take account of special requirements. The basic license does cover use of the reporting function with standard templates, but a separate license is needed for use of Report Builder. .

Log and trend data archiving

24 / 76

Creating and displaying reports via the Web

A user working at a DESIGO WEB client PC can use Web Report Viewer to select existing report templates on the DESIGO INSIGHT computer and to start the logging of momentary values. The report generated in this way is displayed in DESIGO WEB and can be downloaded from the Web server to the client computer as a PDF document for saving or printing.

Reaction Processor

Reaction Processor is an event program capable of monitoring plants and processes throughout the system for the fulfillment of certain criteria (i.e. the occurrence of specific events). If one (or a combination) of these criteria is fulfilled, Reaction Processor initiates the appropriately preconfigured reactions.

Global time scheduler with calendar feature

To enable reactions to be carried out at predefined times of day (time schedules) or on particular dates (calendar/date), the management level of DESIGO INSIGHT includes a global time scheduler with calendar features. In this way, equipment and devices at the automation level can still be controlled on the basis of time or date, even if they do not have their own time schedule or calendar functions.

Every monitored event has an entry in Reaction Processor, with the following format:

If condition(s): "XYZ" fulfilled (event), then start action(s): "a,b,c" (reaction). Users themselves can define these entries in Reaction Processor.

Reaction Processor can monitor the following events: • Time:

Reaction triggered when a specific time is reached.

• Value Change of value (COV, On/Off) as the trigger.

• Combinations of date, time, value, comparison.

• Date: Date (e.g. public holiday as the trigger

• Comparison: Out-of-limits value, greater than, smaller than

Reaction Processor can trigger the following (re)actions: • Override current values in the plant

e.g. setpoint adjustment or switch-control of plant

• Start the creation of a report: Batch commands (with several steps) are also possible

• Start third-party programs Third-party programs are started via command line

• Send report to recipient X, Y or Z via file, e-mail or printer

• Delay Reactions executed after a delay

• Time Scheduler/Calendar For plant/devices without their own time scheduler/calendar functions

Main uses of Reaction Processor

• Reaction Processor can be used to automate repetitive routine user activities. • For plant integrated at the automation level without a time clock or time schedule,

Reaction Processor includes a global time scheduler and calendar program. • Automated open-loop and closed-loop control and switching of plant, based on the

occurrence of events monitored while the plant is running. • Automated initiation 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 leading software standards and are therefore compatible with today's IT security strategies (firewalls, Virtual Private Networks (VPN) etc.).

DESIGO Terminal Server

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 the operation and monitoring programs for 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 DESIGO Terminal Server the optimum solution for professional property managers who need unrestricted access to building data via their intranet or extranet, from any location. All the user requires is a simple, standard network-compatible terminal device such as a PC, Net PC or Web pad with a Microsoft operating system. The terminal device must be a "Thin Client", i.e. one on which no other software components are installed.

Security is a priority: Remote access from client devices is via Microsoft Remote Desktop Web Connection with the highly encrypted Remote Desktop Protocol (RDP)5.0 which uses RSA's RC4 cipher with the option of 40, 56 or 128-bit encryption.

DESIGO Terminal Server is based on the Windows Server 2003 operating system with the Terminal Server component, and runs on standard server hardware. The hardware and software specification depends on how intensively it is used, with the number of users requiring simultaneous access being a decisive factor.

26 / 76

DESIGO WEB

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.

Functions in DESIGO WEB: • Operation of graphics (Plant Viewer) • Operation of data points (Object Viewer) • Alarms and log (Alarm Viewer, Log

Viewer)

• Trend data (Trend Viewer) • Time schedules (Scheduler)

This makes DESIGO WEB the optimum solution for those responsible for technical services (such as the house engineer, building operator or security staff) who track the daily running of the building and need easy access to all the key functions. In addition, it makes new options available, enabling selected building data and user access to be allocated relevantly to tenants and users of the building (e.g. room operation, time schedules and display of room conditions).

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 operator units

Room users and building operators all benefit from an extensive range of operator units which can be used for targeted modification of room conditions or of the whole plant.

19660Z19_02 Figure 23

The right operator unit in the right place: • Monitoring and operation via PX-WEB:

In the event of faults in the plant, DESIGO PX transmits SMS messages and e-mails and allows remote diagnostics via Web client.

• For the house engineer: With optimized operator units, it is easy to check the functioning of the building services plant or to take account of changes in occupancy by modifying the comprehensive time schedules.

• For building users: Optimized operator units provide simple and direct local operation of the plant. So, for example, the room temperature in a meeting room can be adapted to individual requirements, simply and without fuss.

A family of freely programmable automation stations

With its modular system design, DESIGO PX can be ideally adapted to specific requirements and needs, making cost-effective DDC technology a possibility even in small HVAC systems. Whether for new buildings or modernization projects, investment costs are limited to the system components that are actually needed. This innovative system strategy allows phased expansion of DESIGO PX into a building automation and control system as and when required.

DESIGO PX is based on industry standards designed not only for the present but also for communications technologies. BACnet / LonTalk or Ethernet IP are not mere "buzzwords" to us. On the contrary, they emphasize the openness of our systems and our use of the latest communications technology for maximum overall efficiency. Our consistent and coordinated use of standard technologies ensures straightforward and cost-effective integration of third-party systems and components.

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 is ideal for connecting stand-alone third-party systems or open automation 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.

Vendor-neutral protocols: Vendor-specific protocols • BACnet • LONWORKS • KNX S-mode (EIB) • Profibus

• SIMATIC S7, S5 • SIPORT NT (access control) • AlgoRex (fire detection system)

DESIGO SX OPEN

SX OPEN is an innovative integration platform used to connect OPC-based third-party systems to an open BACnet network. SX OPEN forms a powerful bridge between OPC, and BACnet by replicating an OPC client in OPC and a BACnet server on BACnet.

The functions extend far beyond simply mapping and transfer of OPC items to BACnet. For example, the freely programmable level of SX OPEN, at which functions can be interconnected, allows the following:

• Direct mapping of OPC items to BACnet objects, for display and operation by BACnet clients

• Grouping of OPC items to create standard integrated BACnet objects • Event-driven transfer of alarms in the BACnet network • Peer-to-peer communication with other BACnet servers

SX OPEN is especially suitable for the integration of OPC-based third-party systems where there is a need to interconnect functions locally (peer-to-peer communication). It fully compensates for the disadvantages of simple SCADA technology.

The modular software package can be run on standard PC systems with Windows operating systems. Industrial control-panel PCs with no rotating parts (e.g. Siemens micro box) offer reliability, easy maintenance and minimal down time.

Features • BACnet server to BACnet 135-2004

with BACnet/IP • Data objects supported: Analog Input

and Output, Binary Input and Output, Analog and Binary Value, Multistate Input, Output and Value, Device, Notification Class

• Read and write access in accordance with BACnet rules of priority

• OPC Client Data Access 2.05a

Vendor-neutral protocols Vendor-specific protocols, e.g.

OPC server with data access for

• LONWORKS • KNX S-mode (EIB) • M-bus • Modbus • PROFIBUS

• OPC server with data access for third-party systems (e.g. BMA, EMA, access control, video, industrial PLCs, other)

53 / 76

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 LONWORKS devices, LONWORKS 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 for the connection of KNX S-mode (EIB) devices, KNX S-mode (EIB) networks and the DESIGO RXB and RXL room automation systems, and Synco 700

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.

Vendor-neutral protocols: Vendor-specific protocols • BACnet • LONWORKS • KNX S-mode (EIB) • M-bus • Modbus

DESIGO PX BACnet server As an open, native BACnet system, compliant with BACnet standard 135-2001, DESIGO PX is a high-end BACnet server, suitable for connection to higher level BACnet management systems. Each DESIGO PX automation station represents a complete, independent BACnet server in the network.

Technical features: • Open, native interface based on ISO

16484-5, optionally with BACnet/IP, BACnet/LonTalk or BACnet/PTP, depending on device

• European character set ISO 8859-1 • Data objects supported: Analog Input

and Output, Binary Input and Output, Analog and Binary Value, Multistate Input, Output and Value, Schedule and Calendar, Trend Log, Device, Notification Class

• Follows the B-BC device profile (freely programmable controller)

• Up to 1600 simultaneous BACnet COV subscriptions (simultaneous event-driven requests by BACnet clients for values)

• Read and write access in accordance with BACnet rules of priority

• The data points are read with an EDE data point list , and transferred to third-party systems

DESIGO PX automation station

The DESIGO PX automation station has been tested for BACnet compliance, and is authorized to bear the BTL mark issued by the BACnet Testing Laboratory.

DESIGO PX is listed as a BTL-tested device on the BIG EU Web site.

DESIGO PX OPC server

As an open, native BACnet system, DESIGO PX can be set up as an OPC server by use of additional drivers (BACnet Client/OPC Server). A higher-level OPC client of a third-party system then has read and write access to the automation station.

Due to technological constraints when mapping BACnet to OPC, usually only the main BACnet objects are mapped, together with between three and five of their main properties. This is because each individual item of information has to be set up in the OPC as a separate OPC item. Although access to major BACnet objects such as the Scheduler, Calendar and Trend Log is set up in the OPC server, these are not normally implemented in the higher-level OPC client, and can only be implemented at high cost. In respect of functionality and economic efficiency, direct integration with BACnet is always preferable.

PX LON

PX LON connects LONWORKS networks to DESIGO and maps LONWORKS network variables to BACnet data points.

Main functions of PX LON: • Compression of DESIGO RXC room

controller and third-party device data • Maps DESIGO RXC applications to

BACnet for operation and monitoring (grouped as HVAC, lighting and blind control functions)

• Higher-level control and optimization functions, such as room and zone-based groups, time control, and system functions such as changeover, summer/winter compensation etc.

• Alarm handling, device monitoring • Trend storage

PX LON maps RXC applications in such a way as to produce a room view. This enables the rooms to be grouped together, for shared occupancy programs, or for shared commands for the control of lighting or blinds, for example.

PX M-bus

PX M-bus connects the M-bus consumption meters to the DESIGO system and maps meter readings and device-related meter information to BACnet data points.

Main functions of PX M-bus • Measurement of consumption data and

remote monitoring of max. 250 consumption and heat meters or up to 2,000 BACnet I/O objects

• Compression of data from consumption and heat meters at the automation level

• Alarm handling, device monitoring • Trend storage to record meter readings

PX Modbus

PX Modbus connects Modbus devices or networks supporting the Modbus protocol as specified by Modicon to the DESIGO system and maps their data points to BACnet data points. PX Modbus is particularly suitable for integrating industrial controls or chillers and linking them to the automation process.

PX KNX

PX KNX connects KNX S-mode (EIB) networks to DESIGO and maps KNX S-mode (EIB) group addresses to BACnet data points.

Main functions of PX KNX • Compression of the data from the

DESIGO RXB room controllers and other KNX data points at the automation level

• Mapping of DESIGO RXB, RXL, Synco 700 and other KNX applications to BACnet for operation and monitoring (grouped as HVAC, lighting and blind control functions)

• Higher-level control and optimization functions, such as room and zone-based groups, time control, and system functions such as changeover, summer/winter compensation etc.

• Alarm handling, device monitoring • Trend storage

57 / 76

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 for the 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.

Figure 33

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.

58 / 76

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.

Figure 34 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.

• 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" (inputs and outputs) of various blocks.

Libraries

PX Design incorporates comprehensive libraries in which the functions, function blocks and compounds are stored. The libraries contain images of actual plant, aggregates and components in a structure which can be used equally for design engineering, control, operation and monitoring and display.

The automation level: SIMATIC S7 for industrial applications

With the SIMATIC S7 automation stations, Siemens Building Technologies offers a complete and consistent automation strategy for all types of building. A versatile range of communication options combined with a modular design enables these automation stations to be tailored to virtually any task, making them ideal for industrial applications.

The key benefits of SIMATIC S7: • Standard communication via Ethernet

TCP/IP, PROFIBUS DP, KNX S-mode (EIB), LONWORKS

• Distributed peripheral devices with DESIGO I/O or SIMATIC ET 2000

• S7 WEB for operation, display and maintenance

• Software library with standard and tested modules

A comprehensive software library is available, with standard and tested function blocks for all tasks associated with heating, ventilation, conditioning and other building services. The modular software blocks from this library can be freely combined, and configured with the necessary operating parameters, as required for the individual customer’s plant.

The communications network is critical to the operation of the building services and is therefore of special importance. For optimum industrial communications, we offer components and networks which ensure continuity from the management level to the field level. In our view, open system connections to office networks via TCP/IP are just as self-evident as the integration of third-party components via a wide range of protocols and special link modules.

SIMATIC S7 modular automation station

SIMATIC S7 is the modular automation station for all standard HVAC plant. The modular, fan-free design, simple implementation of distributed structures, and user-friendliness of SIMATIC S7 make it the convenient and cost-effective solution for a wide range of functions.

Several CPUs with different levels of performance, plus an extensive range of modules with numerous convenient functions enable the user to select only the modules actually required for the application concerned. If the required function is later extended, the automation station can simply be upgraded as required, by adding further modules.

A SIMATIC system comprises:

• A central processing unit (CPU): Various CPUs are available for different performance requirements, including CPUs with integrated inputs/outputs and associated functions, and some CPUs with an integrated PROFIBUS DP interface.

• Signal modules (SM) for digital and analog inputs/outputs • Communication modules for bus coupling and point-to-point connections • Power supply modules for connection of the SIMATIC S7 to a supply voltage of

AC 120/230 V or DC 24 V Use:

• Connected to Ethernet TCP/IP system bus • Stand-alone, with touch panel TP177B

Local operation and monitoring

The SIMATIC OP7/OP17 operator unit is used for local operation and monitoring of the SIMATIC S7 automation stations. It provides access to all data points and the associated parameters (e.g. messages and switch commands) in all plant. The SIMATIC OP7 operator unit has a four-line text display, and the SIMATIC OP17 unit an eight-line display. Normally the unit is built into the control panel door.

The SIMATIC operator units enable the user to locate faults, operate and optimize the operation of plant, and modify switch times.

The advantages: • Clear and uniform operating philosophy

for easy operation • Easy-to-understand user guidance,

with plant view, aggregate view and data point view.

• Common alarm displays with user guidance

• Up to 4 SIMATIC S7-300 or SIMATIC S7-400 automation stations may be connected

• Password protection

Web-based operation and monitoring with S7 WEB

When it comes to operation and monitoring in the field of building automation, S7 WEB sets new standards. A standard Web browser (e.g. Internet Explorer) can be used to operate and monitor the SIMATIC S7 automation stations (SIMATIC S7-300/S7-400) via the LAN, intranet or Internet. The hardware platform is represented by the standard communications processors.

Operation takes place using standardized dialog boxes in HTML format. TCP/IP communications make it possible to operate and view heating, ventilation and air conditioning plant from any standard PC with a Web browser.

S7 WEB allows the user to locate faults from anywhere in the TCP/IP network and to operate and optimize the operation of the plant.

The features: • Modern, forward-looking design • Engineering supported by software

tools • Easy to operate, with uniform and

intuitive guidance of the user through the graphical hierarchy and operating philosophy

• Common alarm displays with user guidance

• E-mail transmission • Plant graphics • Access from any location via LAN,

intranet or Internet • Use of any standard PC with a Web

browser, without installing special software

68 / 76

The field level: SIMATIC ET 200S

In conjunction with SIMATIC S7, digital and analog inputs and outputs can be linked to the central control system via the PROFIBUS DP field bus system.

The peripheral devices can perform central control sub-functions independently. Sections of the plant can be tested and commissioned in advance. In the event of an error, standalone elements can continue to operate autonomously.

The distributed peripheral devices for SIMATIC come in different sizes, formats and protection classes, and optionally, even with a freely programmable CPU. ET 200S is particularly suitable for building automation and control tasks.

Key benefits: Less wiring is required, and the plant is significantly more flexible and reliable. The extensive range of modules and the uniform approach, throughout the system, to engineering, mounting and programming mean that ET 200S can be used as a universal peripheral device system. The peripheral-device modules can be combined as required.

Network gateways to DESIGO I/O, LONWORKS and KNX S-mode (EIB)

Based on SIMATIC S7, Siemens Building Technologies offers an integration platform based on SIMATIC S7, for communication at the automation level. SIMATIC S7 is connected to the standard communications systems, LONWORKS and KNX S-mode (EIB) of the building automation and control system, by means of two network gateways, the DP/LON Link and the DP/EIB Link. This is the means by which the LONWORKS and KNX S-mode (EIB) field buses are integrated into PROFIBUS DP. In addition to the network access described, other means of access, such as the DP/AS interface link are also available.

Gateway from PROFIBUS DP to DESIGO I/O

The DP/P-bus link integrates the proven DESIGO P-bus input/output modules into SIMATIC S7. Within the SIMATIC system, the DESIGO I/Os (PTM modules) are treated as standard PROFIBUS DP data points and can therefore be accessed in the SIMATIC system.

Gateway from PROFIBUS DP to LonWorks

The DP/LON link integrates the LONWORKS bus of the building automation and control system into the standard communications system, PROFIBUS DP. For the individual room control range, DESIGO RX, the most commonly used applications are available for automated engineering.

Gateway from PROFIBUS DP to EIB The DP/EIB link is used to connect the two open standard communications systems PROFIBUS DP and the building automation bus, EIB. The DP/EIB Link is especially designed for tasks associated with control of lighting and blinds in the context of the electrical installation.

The construction of the device makes it suitable for installation in control panels and sub-distribution boards.

69 / 76

SIMATIC S7 automation software

Highly modular software blocks permit maximum flexibility for the solution of complex individual tasks. Off-the-shelf "Typicals" (typical block configurations) are available for components associated with heating, ventilation and air conditioning. Standard tasks can be implemented efficiently and reliably using these Typicals. The Typicals, themselves, are composed of software blocks and can therefore be modified as required. In this way, the software combines flexibility with efficient engineering.

Software blocks

Software blocks are general control blocks which offer the user the scope and flexibility of a programmable logic controller (PLC). These blocks include logic blocks, time elements and calculator blocks.

Special control and calculator blocks for building automation and control are also available. Examples include twin-pump control, start-up control, enthalpy calculation and the calculation of heat quantity.

Input and output modules ensure the logging and control of field devices and equipment such as heating coils, fans etc.

Optimizer blocks enable the plant to be operated at the specified comfort level while consuming the smallest possible amount of energy. These blocks include the following, for example: time scheduling, Optimized Start/Stop Control (OSSC), enthalpy conversion, summer night ventilation, optimization of the h,x chart, maximum demand control.

Third-party peripheral-device blocks allow the user to obtain full access to the data in the third-party system and field devices.

Typicals

Air-handling components (such as heating coils, cooling coils, fans, dampers and air washers) are available for quick creation of ventilation and air conditioning systems. The blocks include components such as heating circuits and boilers, ideal for the automation of heating systems. The continuously expanding library of "Typicals" also includes components for chillers and special applications.
