  10. 10. SCADA/HMI building automation system advantages Using SCADA platforms for your building automation system allows you to get exactly the features and capabilities you want now and in the future as your needs grow. SCADA systems are powerful, robust and flexible. SCADA is robust Manufacturers, water treatment and other operations have been relying for decades on SCADA systems to control their processes.
  11. 11. Integratability  Over the years, users have demanded that SCADA system developers enable connectivity with the unlike systems and networks with their plants.  This openness is highly beneficial for building automation systems with the many diverse component systems to be integrated. Flexibility  SCADA systems are scalable and upgradeable. Reporting  Which reports do you want where at what time? Want to see status on all your systems from any web browser anywhere, even from your smartphone?  With SCADA, you can do it. As you can also, if you chose, enable control over remote connections.

  13. 13. System Concepts of SCADA Riz Jayro Lagang Stella Amor Hermias
  14. 14. System Concept of SCADA SCADA  is a kind of software application program used for the process control and gather real time from remote locations for exercising this control on equipment and conditions.
  15. 15. COMPOSITION  Input/output signal hardware System Concept of SCADA SCADA
  16. 16.  Network System Concept of SCADA SCADA
  17. 17.  Human Machine Interface (HMI) System Concept of SCADA SCADA
  18. 18. •Controllers System Concept of SCADA  Controllers
  19. 19.  Database (A structured set of data held in a computer, esp. one that is accessible in various ways) System Concept of SCADA
  20. 20. Communication and software  The SCADA consist of Hardware and Software components.  The hardware collects and feed data into a computer with SCADA software installed.  The data is then processed by the computer before presenting it in a timely manner. System Concept of SCADA SCADA
  21. 21. SCADA SYSTEM Signal hardware (I/O) controllers networks User interface (HMI) Communications Equipment and software
  22. 22. CONTROL/ MONITOR FUNCTION  A system or the complete site is usually spread over a long geographical distance, SCADA is the central system for control and monitor of such a site or system. System Concept of SCADA SCADA
  23. 23.  A Programmable Logic Controller (PLC) or Remote Terminal Unit automatically performs the main site control process.  The host control functions in most cases are limited to the capability of supervisory level or site override. System Concept of SCADA SCADA
  24. 24. SCADA SUBSYSTEM  HMI-is the apparatus which presents the process data to a human operator, and through this, the human operator monitors and control the process.  a supervisory(computer) system, gathering (acquiring) data on the process and sending commands(control) to the process. System Concept of SCADA SCADA
  25. 25.  RTU-connecting to sensors on the process, converting sensor signals and sending digital data to the supervisory systems.  PLC-used as field devices because they are more economical, versatile, flexible, and configurable than special purpose RTU.  Communication infrastructure connecting the supervisory system to the RTU. System Concept of SCADA
  26. 26. System Concept of SCADA
  27. 27. System Concept of SCADA
  28. 28.  Data Acquisition begins at the RTU or PLC level and includes meter readings and equipment status reports that are communicated to SCADA as required.  Data is then compiled and formatted in such a way that a control room operator using the HMI can make supervisory decisions to adjust or override normal RTU (PLC) controls. System Concept of SCADA SCADA
  29. 29. Remote Terminal Unit (RTU) Jose Kiimer Bagabuyo Ronald Anthony Santos
  30. 30. What is RTU? Remote Terminal Unit
  31. 31. What is RTU? An RTU monitors the field digital and analog parameters and transmits data to the Central Monitoring Station. It contains setup software to connect data input streams to data output streams, define communication protocols, and troubleshoot installation problems. An RTU may consist of one complex circuit card consisting of various sections needed to do a custom fitted function or may consist of many circuit cards including CPU or processing with communications interface(s), and one or more of the following: (AI) analog input, (DI) digital input, (DO/CO) digital or control (relay) output, or (AO) analog output card(s). SCADA
  32. 32. RTU  a microprocessor-controlled electronic device that interfaces objects in the physical world to a distributed control system or SCADA (supervisory control and data acquisition) system by transmitting telemetry data to a master system, and by using messages from the master supervisory system to control connected objects.  Another term that may be used for RTU is remote telemetry unit, the common usage term varies with the application area generally.
  33. 33. Two basic types of RTU: 1. Single board RTU 2. Modular RTU SCADA
  34. 34. Single board RTU which is compact, and contains all I/O on a single board. The single board RTU normally has fixed I/O (eg.16 digital inputs, 8 digital outputs, 8 analogue inputs, and say 4 analogue outputs).
  35. 35. Modular RTU which has a separate CPU module, and can have other modules added, normally by plugging into a common "backplane" (a bit like a PC motherboard and plug in peripheral cards) is designed to be expanded by adding additional modules.
  37. 37. Architecture 1.1 Power supply 1.2 Digital or Status inputs 1.3 Analog inputs 1.4 Digital (control) outputs 1.5 Analog outputs 1.6 Software and logic control 1.7 Communications 1.7.1 IED communications 1.7.2 Master communications SCADA
  38. 38.  RTUs differ from programmable logic controllers (PLCs) in that RTUs are more suitable for wide geographical telemetry.  RTUs, PLCs and DCS are increasingly beginning to overlap in responsibilities, and many vendors sell RTUs with PLC-like features and vice versa.  In addition, some vendors now supply RTUs with comprehensive functionality pre-defined, sometimes with PLC extensions and/or interfaces for configuration.  Some suppliers of RTUs have created simple graphical user interfaces GUI to enable customers to configure their RTUs easily. In some applications data loggers are used in similar applications. Comparison with other control systems SCADA
  39. 39. Remote monitoring of functions and instrumentation for:  Oil and gas (offshore platforms, onshore oil wells).  Networks of pump stations (wastewater collection, or for water supply).  Environmental monitoring systems (pollution, air quality, emissions monitoring).  Mine sites.  Air traffic equipment such as navigation aids. Applications of RTU SCADA
  40. 40. Remote monitoring and control of functions and instrumentation for:  Hydro-graphic (water supply, reservoirs, sewerage systems).  Electrical power transmission networks and associated equipment.  Natural gas networks and associated equipment.  Outdoor warning sirens. Applications of RTU SCADA
  41. 41. FUTURE TRENDS IN SCADA Julius Jay Sinados
  42. 42. FUTURE TRENDS IN SCADA First generation: "Monolithic“ Second generation: "Distributed“ Third generation: "Networked"
  43. 43. First generation: "Monolithic"  In the first generation, computing was done by mainframe computers.  Networks did not exist at the time SCADA was developed.  Thus SCADA systems were independent systems with no connectivity to other systems. Wide Area Networks were later designed by RTU vendors to communicate with the RTU.  The first-generation SCADA system was redundant since a back-up mainframe system was connected at the bus level and was used in the event of failure of the primary mainframe system. FUTURE TRENDS IN SCADA SCADA
  44. 44. Second generation: "Distributed" The processing was distributed across multiple stations which were connected through a LAN and they shared information in real time. Each station was responsible for a particular task thus making the size and cost of each station less than the one used in First Generation. FUTURE TRENDS IN SCADA SCADA
  45. 45. Third generation: "Networked" Due to the usage of standard protocols and the fact that many networked SCADA systems are accessible from the Internet, the systems are potentially vulnerable to remote attack. FUTURE TRENDS IN SCADA SCADA
