The general building dispatch system is designed to integrate all life support systems of buildings: heating, ventilation, air conditioning, access control, video surveillance systems fire alarm etc. The integration of all these systems provides additional comfort, safety and improves energy efficiency.
Receiving all information in a single center allows you to increase the efficiency of the maintenance staff and, as a result, reduce the cost of operating the building.
Controllers for building management
Implementing DESIGO™ does not require quick, minute-to-minute investments. Already installed automation components can be completely adapted to your needs. This allows you to limit your investment to the features you need right now. Thanks to the modular structure of DESIGO INSIGHT, you can expand your system at any time.
The DESIGO™ building automation and control system is open, which means it is possible to integrate third-party systems at any level of the DESIGO™ system.
DESIGO™ allows you to integrate automation systems and components that support OPC, BACNet, LON, EIB, KNX, MOD-bus and M-bus interfaces. This ability allows DESIGO™ to be used for expansion and modernization existing systems automation without replacing automation equipment.
To exchange information, DESIGO™ uses standard exchange protocols at all levels of automation.
Maintaining energy efficiency and cost optimization in buildings is also a mandatory feature of all systems. The Siemens DESIGO building control and automation system satisfies all the above requirements in the best possible way. DESIGO creates a comfortable working environment in the building, and at the same time it is easy for maintenance personnel and service technicians to work with. The system automatically or under operator control carries out control and monitoring tasks. DESIGO is not limited to the control of heating, ventilation and air conditioning systems - it is a comprehensive integrated building management system covering all building services (lighting, blind control, safety and security, access control and energy distribution).
DESIGO™ provides a user-friendly, intuitive interface at all levels of the system. The local operator console offers an easy-to-understand, intuitive interface that allows you to obtain information even in graphical form.
Work with the control station is based on the principles of MS Windows organization. This means that operating personnel can learn how to optimally use the dispatch system in a short period of time.
A remarkable feature of DESIGO INSIGHT is that the application complies with industry standards at the level of structure and components. Therefore, the software is designed for Windows, allowing you to fully use the functions of these operating systems.
Using DESIGO™ WEB, the dispatch system becomes accessible via the Internet. This means that the dispatch and control function can be accessed via an Internet browser at any time and from anywhere in the world. This new degree of freedom allows for more efficient control of life support systems.
The use of BACNET, LON, PROFIBUS and Ethernet TCP/IP Technologies provides maximum flexibility as building use changes and helps you make better use of your workforce.
Each level of the system operates autonomously and independently of the upper level. This makes commissioning simple and guarantees minimal system downtime. The implementation of the DESIGO system provides the following functionality, the list of which is constantly expanding:
Optimal indoor climate
Systems can be integrated into the system refrigeration units, hot water supply, ventilation, heating boilers and pumping stations. It is possible to configure all building subsystems as a whole to optimize their operation, control and data collection.
Integrated Building Management Security Systems
DESIGO allows you to combine data from the subsystem of security alarm systems, access control and video surveillance in one system and presents the resulting security information in a clear and convenient form.
Modern projects often require the integration of power supply, conversion and distribution installations. In addition to detailed data on electricity consumption, the user also receives visual information about the current state of his energy installation and accurate fault diagnosis. Direct control and optimization of energy consumption together with ventilation and heating systems is possible.
The DESIGO system can easily integrate the control of doors, elevators and escalators, as well as special solutions for any commercial purpose, such as hotel room management systems, etc.
The DESIGO system uses the open communication protocol BACnet (Building Automation and Control Network) to exchange information between DESIGO PX automation stations and the control plane.
BACnet, the global standard of the future, was originally developed specifically for building installations, but is now widely used for fire safety and security systems. For direct integration into existing communication infrastructures, DESIGO uses BACnet over LonTalk and BACnet over Ethernet/IP. When it is necessary to connect specialized controllers of the DESIGO RX series to control the microclimate in individual rooms, LonWorks or KNX standards are used, which are ideal for these purposes.
To organize the cost-effective operation of modern buildings, it is necessary to carefully consider the planning, implementation and maintenance of all engineering equipment at the project stage. The DESIGO integrated building automation system integrates different types of building equipment into a single functional module that manages, monitors, records and analyzes all systems and processes.
General data on the condition of building equipment is transferred from DESIGO to the Computer Asset Management (CAFM) program. The benefits are obvious: the ability to reduce operating costs, protect capital investments in the long term, and enhance site safety and security.
DESIGO INSIGHT - accessible representation of complex processes in building control
The processes occurring at the level of the building automation and control system are very complex, so here important role plays a clear graphical representation of information. The same is true for direct and precise work. DESIGO INSIGHT makes it easy to communicate complex processes to the user.
DESIGO INSIGHT is used for centralized collection, processing and evaluation of alarm signals from all integrated systems. Using a powerful alarm routing system, alarms can be sent via SMS, fax, e-mail or pager to operators, wherever they are and regardless of whether the control station is serviced or not.
DESIGO INSIGHT software is fully integrated to process real-time data trends as well as historical data, providing process visibility and rapid optimization of plant parameters.
Universal, convenient operation of all building systems increases transparency, reduces maintenance costs and allows the use of less qualified personnel. Even an inexperienced worker always receives hints on what to do from DESIGO.
DESIGO INSIGHT can be used in projects of any size: from small buildings with a few data points to giant building complexes with many thousands of data points. In an office or industrial building, hotel or hospital, DESIGO INSIGHT is the right solution to satisfy any need for automation and visualization of building processes.
The coordinated and targeted use of standard technologies and an integrated SCADA system will allow third-party systems to be easily and cost-effectively connected to DESIGO INSIGHT via BACnet, OPC (OLE for Process Control, OLE - Communication and Object Implementation) or using a web interface, etc.
Thanks to various standard interfaces, DESIGO can be integrated cost-effectively into customer systems such as asset management or service management. Another feature that simplifies the engineer’s work: data from DESIGO INSIGHT can be moved to MS Office applications for further analysis.
The DESIGO INSIGHT control station is based on a variety of standard technologies such as ActiveX, DCOM, OLE and MS SQL server. That's why it can be used directly on your PC and easily integrated into a modern business environment.
To collect alarms and fault conditions, report templates are available for plant operating status log entries. They can also be selected and filled in via DESIGO PX - a scalable automation system.
Versatility in the true sense of the word: DESIGO PX monitors and controls heating, ventilation and air conditioning systems and other systems serving buildings. You can see, on the one hand, that the range of automation stations and operator panels is very large, and on the other hand, that the level of openness of the system is very high.
The innovative and intelligent DESIGO TX-I/O family of modules for DESIGO PX modular controllers combines many years of experience with cutting-edge technology to optimally meet all the requirements of modern modular controllers for building subsystem control. The benefits of the new line of DESIGO TX-I/O modules are clearly revealed not only during the design and implementation of the system, but also during its operation and maintenance.
Programmable Controller Family
The DESIGO PX family of freely programmable automation stations allows the most flexible implementation of the most complex algorithms, incorporated by technologists into the design of the building's engineering equipment. Supporting system functions such as alarm reporting, scheduling programs and data trending are widely used to meet the most demanding building maintenance requirements. Automation stations operate autonomously and decentralized. Data transmission is organized via the open BACnet protocol via LonTalk or Ethernet/IP. The controllers are presented in two versions: compact and modular series.
DESIGO PX Compact Series
The compact series automation stations support communication using the BACnet protocol via LonTalk or IP and have terminals directly on the controller base for connecting peripheral equipment.
DESIGO PX Modular series with DESIGO TX-I/O
At the design stage, automation stations of a modular series are flexibly equipped with the required number of input-output modules, or it is possible to add modules when expanding the system during the commissioning and operation process. Specialized modules of the DESIGO TX-I/O series are connected to automation stations via a data bus. This line of modules has a modern design, takes into account the convenience of placement in the automation panel, has a compact design and is flexible in setup and programming. Some types of input and output modules allow installations to be controlled manually, thereby simplifying setup and maintenance work.
- Modular design: communication via BACnet via LonTalk or IP, built-in web server and remote control;
- flexible distribution of data points;
- optional - manual control with built-in diagnostic functions, including LEDs or LCD display, automatic connection to the data bus;
- interface terminal block;
- optimal adaptation to building systems.
For programming, commissioning and maintenance of automation stations, comprehensive software with many specially developed application software blocks. Programming is based on graphical program blocks and application modules created in the DESIGO XWORKS programming environment. The graphical user interface of the software ensures the efficient work of service engineers. Commissioning is made easier with support functions such as event logging, reporting and trend analysis.
The DESIGO PX series is created on the basis of many years of experience of hundreds of leading experts in the development and implementation of building automation products. Software DESIGO XWORKS and the applications for building subsystems have been extensively tested in the laboratory, proven to work in a huge number of projects and guarantee a high level of quality not only now, but also in the future.
DESIGO WEB - operational control of the building at any time of the day from any access point.
Malfunctions and malfunctions of the installation always happen at inconvenient times for you. The building operator must be able to immediately monitor the building processes at any time and from any location. Modern Web technology makes this easy to do.
Global exchange of information regardless of time and place
With DESIGO WEB, the building operator can take advantage of global information exchange via Intranet or Internet, regardless of time and location. DESIGO WEB identifies installation failures at any time of the day or night, and can inform you about this using modern Internet- technologies. If necessary, alarm messages can be sent via SMS, fax or email. The installation's graphical interface, automatic HTML reports, trends and statistics are now available to the building's chief engineer at any time of the day!
The engineer responsible for the trouble-free operation of the building must be available at all times. Even if he is outside the building, when the set temperature or pressure in the pipeline reaches a critical point, the system will instantly notify him via SMS, fax or email. If necessary, corrective actions can be taken immediately: directly from handy devices such as a mobile phone, laptop or personal computer.
DESIGO PX-WEB - the optimal solution for small installations
To service buildings with typical and standard installations, there is no need to install additional software. It is enough to use the hardware module with the DESIGO PX-WEB web interface.
This cost-effective solution for small systems allows users to operate the system through a web browser, just like using a local operator console on site. The pre-configured web server is directly built into the hardware and therefore no PC web server is needed.
DESIGO RX - optimal comfort in individual rooms
In practice, each room requires special conditions, which must be created by a building control and automation system. DESIGO RX offers maximum openness and flexibility to meet different space requirements, taking into account possible room redevelopment.
If individual offices, shops or restaurants need to create comfortable climatic conditions, then DESIGO RX controllers will be indispensable. DESIGO RX is a modular, adaptable room automation system for controlling hair dryer units, radiator heating, VAV boxes, as well as room lighting and motorized blinds. As an additional option, it is possible to connect third-party equipment using the LonWorks or KNX protocols. Thanks to the use of global standards LonWorks and KNX, investors' investments will be protected in the long term. DESIGO RX can be quickly and cost-effectively adapted to any new customer requirements.
Flexible use of space plays an increasingly important role in modern buildings. To quickly and easily redesign a space without changing wiring, you can use DESIGO RX equipment. In this case, it is only necessary to change the software connections between the controllers and the room units. There is a large library of ready-to-use room applications that are easily downloaded to the controllers.
Thanks to the use of wireless communications, DESIGO RX equipment can be easily installed in areas with strict architectural requirements. Universal operator units for controlling lighting, blinds and climate control systems have received awards for excellent design at international exhibitions. DESIGO RX meets the latest technical requirements for lighting and climate control in individual rooms.
Direct integration into the DESIGO building control and automation system provides a high level of transparency in the operation of premises.
The use of Lon technology allows for decentralized control, which increases the reliability of the system. An alternative is KNX technology, which is widely used in Europe to collect information and control electrical installations.

Dispatch system designed for remote display of the collection and storage of work data technological equipment building or production process, it transmits information about the parameters of ongoing processes, operating modes of engineering systems, and emergency situations. The dispatch system interface allows the operator to remotely set the operating modes of the system as a whole or individual equipment.
The requirement for dispatch systems in modern buildings is determined by SP 31-110-2003 “Design and installation of electrical installations of residential and public buildings.” VSN 60-89 “Communication, signaling and dispatching devices for engineering equipment of residential and public buildings. Design standards” - regulates the design of dispatch systems.
Thus, the main purpose of the dispatch system is to centralize control and management of the building.
Sometimes confusion arises when a building management system is defined as a BMS building management system. This is due to the fact that controllers and SCADA software of BMS systems are used in dispatching. However, the dispatch system is the interface part of the intelligent building system; it only displays information on the console and allows the operator to manually control part of the processes, albeit remotely. Algorithms for optimal and economical interaction between building subsystems must be developed by the automation project and programmed in control controllers, only then the operator is freed from making most routine decisions.
The dispatch system is not a full-fledged system automation! It performs functions related to display - “supervisory control” and manual remote control - “supervisory control” of engineering systems.
Typically, the functions of the dispatch system include:
- Collection of data from devices and visual display of processes occurring with the building’s engineering equipment (for modern systems, using SCADA);
- Timely detection of emergency situations, accident prevention;
- Generating and sending alarm messages to responsible persons;
- Remote control of engineering systems devices;
- Collection and storage of instrument readings in automatic or manual mode;
- Presentation of data in graphical and tabular form;
- Maintaining reports on energy consumption, generating reports automatically and at the request of the operator;
- If necessary, transfer data to a higher priority remote control.
The dispatcher's console displays information flow from the following systems:
- Supply and exhaust ventilation;
- Air conditioning and refrigeration;
- Heating;
- Heating supply (ITP or boiler equipment);
- Water supply, water treatment, sewerage;
- Elevator and escalator equipment;
- Power supply and electric lighting;
- Fire alarm and building security systems;
- Sound control systems;
- Fire automatics (smoke ventilation and fire extinguishing);
- Other systems related to production or process control.
Parameters of the temperature of outside air, chilled water to/from the ventilation system, chilled ethylene glycol, heated heating water can be displayed; chilled water or ethylene glycol pressure values of ventilation and air conditioning systems; control valve positions; engine power circulation pumps or fans; ; data on filter clogging; alarm about the threat of freezing of air heaters; information about the condition of elevators, supported by video data; state of circuit breakers in electrical panels, etc.
Equipment control in dispatching is limited to the ability to enable certain operating modes, for example, system start-up mode in winter or summer, maximum performance mode, emergency shutdown of the installation, manual switching from the main to the backup pump, etc. In theory, the dispatcher has the ability to control each of the devices that have a drive, but in practice, one person physiologically will not be able to manually control a large engineering system.
Such a system is managed 24/7 by qualified personnel who have completed specialized training courses. In addition, for each system during the design, commissioning and operation process, technologists develop action protocols for possible emergency situations.
Capabilities of modern dispatch systems
Modern dispatch systems are increasingly implemented on controllers and software of BMS systems. This leads to a large number of software options for customizing their functions. In general, dispatch systems should provide:
- An up-to-date and complete picture of the state of all engineering systems at any time;
- Convenient and intuitive graphical interface;
- Quick response to emergency situations;
- Possibility of issuing emergency messages on the monitor screen, printer, remote computer, mobile phone;
- Registration of all system events, which in many cases makes it possible to determine the cause emergency situation, its culprit, and also prevent its occurrence in the future;
- Connect to the system remotely via an Internet browser;
- Quick and adequate response to changing environmental conditions;
- Automatic calculation of engine hours, equipment time between failures and warning of the need for maintenance and preventive maintenance;
- Wide range of systems management capabilities, which allows reducing the number of maintenance personnel;
- The ability to collect statistical information, form samples, and compare cost forecasting graphs.
The difference between a dispatch system and a building automatic control and dispatch system (ACS)
The main differences between the functions of the engineering equipment dispatch system and the automatic building control system are visible in the diagrams below. Typical scheme for dispatching engineering systems of a facility
Typical scheme for automation and dispatch of facility engineering systems (synonyms: BMS, intelligent building)
Thus, The dispatch subsystem is only part of the BMS building management system.
Equipment and software for dispatch systems
The task of dispatching is to display information and provide control capabilities; therefore, the main elements of the dispatching system are operator software and interface converters, often installed in automation panels of engineering equipment.
As a rule, modern automation controllers have the ability to work with SCADA software of the dispatch system; they are also interface converters. The software provides the implementation of such functions as:
- Displaying information in the form of mnemonic diagrams with real-time display of measurement values, values of controller settings, various icons and other graphic objects;
- Generation and issuance of emergency messages;
- Maintaining archives (trends) for all hardware signals and calculated process variables;
- The ability to correct the operation of the system without stopping it;
- Ability to search and filter archive records according to a number of selection criteria; the ability to generate reports based on user-defined templates; viewing archived information in the form of graphs and tables;
- Possibility of creating schedules, multi-level access and other functions of computer control systems.
Data transfer from the local automation system to the SCADA dispatch system can be carried out directly or through the OPC (Open Platform Communication) server interface. Wherein OPC server is a translator between the language that the installed equipment understands and the language of the dispatcher software interface.
The main goal of the OPC standard was to provide the ability collaboration automation tools operating on different hardware platforms, in different industrial networks and manufactured by different companies.
After the OPC standard was introduced, almost all SCADA packages were redesigned as OPC clients, and every hardware manufacturer began to supply their controllers, I/O modules, smart sensors and actuators with a standard OPC server. Thanks to the advent of interface standardization, it became possible to connect any physical device to any SCADA, as long as they both complied with the OPC standard. Developers have the opportunity to design only one driver for all SCADA packages, and users have the opportunity to select equipment and programs without the previous restrictions on their compatibility.
IP equipment
90% of modern dispatch systems have the ability to exchange information over IP networks. Data conversion into the appropriate protocols occurs either directly in the controllers, or on top-level servers (Schneider Electric Automation Server), or through gateways, for example, Xenta-911.
With the reduction in cost of IP equipment, the functions of data transmission to the network are gradually spreading to field devices (valves, frequency converters, etc.), however, this solution is still more expensive in any case, and also requires the development of a stable and safe SCS on site, this is true it's an expensive undertaking.
IP equipment for automation and control systems of engineering systems is selected depending on the requirements for its functions. As a rule, it is enough to have a software interface between the dispatch system and the enterprise’s IP network, and it becomes possible to connect additional information to the SCADA system. In particular, for visual monitoring of important nodes or premises from the control center, IP cameras of industrial television or security systems are connected to the system.
Development and design of dispatch systems
The design of the dispatch system is carried out as part of a set of drawings of the building automation and dispatch system. The signals output to the dispatcher console are determined by the developers of the building system technology.
Design standard: VSN 60-89 “Communication, alarm and dispatch devices for engineering equipment of residential and public buildings. Design standards"
A dispatch system project will usually contain the following sheets:
As part of the dispatch project, an automated dispatcher workstation is also being developed. Depending on the scale of the system, it can be equipped with:
A shield with a printed mnemonic diagram(at present, such systems are becoming less and less common in production);
PC with SCADA program installed;
PC with web interface to the system server controller (example: automation server Schneider Electric);
PC with installed SCADA system with access to several monitors and a monitor wall.
Automation of building engineering systems pursues an important goal - automatic control of all communications existing at the facility. The alternative option, which involves manual control, is hopelessly outdated - it is necessary to conclude contracts with personnel, constant control over all parameters and indicators, the risk of the human factor increases significantly, and one mistake can lead to serious consequences, including accidents.
Were you able to achieve optimal temperatures? Is the system maintaining normal pressure? Does the voltage meet the stated parameters? Are the volumes of coolant in the operating circuit sufficient? This is far from full list questions to be answered automated system.
The exact set of functions of the complex depends on its type and configuration. Our company’s specialists are ready to design and install systems of any complexity. Most simple options perform the following tasks:
- Controlling the functioning of modules that make up heating, ventilation and air conditioning systems, reading their performance indicators, checking for compliance with standard values;
- Actuation of dampers and valves, if necessary;
- Safety guarantee. For example, if the system detects the immobility of air masses, the heating elements are turned off. If water heating begins to freeze, the temperature of the coolant automatically increases, which eliminates the formation of ice in the circuit, which can provoke ruptures and complex restoration work;
- Protection of working modules from activities under increased load, errors during the connection process, short circuits, excessive heating;
- Assessment of the condition of working modules;
- Adjusting productivity in accordance with current needs, which ensures the most comfortable conditions at the facility, and also eliminates the overconsumption of energy resources;
- Constant monitoring temperature conditions in each of the controlled premises;
- Changing operating parameters in accordance with specified algorithms without the need for human intervention.
Automation and dispatching of building engineering systems contributes to achieving maximum safety of their work and minimizes the number of accidents. If the automation detects serious deviations from standard indicators, a corresponding signal is sent to the control panel, where the operator or microprocessor makes a decision on further actions. For example, if a sensor detects that the pressure in the water supply has seriously dropped, the emergency section is switched off. If a threat of failure is detected heating element due to a critical increase in temperature, voltage is no longer supplied to it.
Commands are sent from the control panel to change the operating parameters of the system in accordance with external conditions. For example, it becomes cold in a heated room - this is diagnosed by a temperature sensor, and a command is sent to increase the boiler power. If deviations from standard voltage parameters are observed in the autonomous power grid, stabilizers or more powerful modules and backup generators are activated.
