Distributed Control System

  1. 1. Distributed Control System Group D Louay Sirwi 213627 Abdallah Jafar 214973 Dr. H. Shabaik SE – 401
  2. 2. Introduction <ul><li>(DCS) was Introduced in the late 1970’s </li></ul><ul><li>Monitor and control distributed equipment with remote human intervention </li></ul><ul><li>Dangerous zones and far areas </li></ul>
  3. 3. What is a DCS? <ul><li>A Distributed Control System integrates the PLCs and process controllers of a process line into a coordinated, interactive system. </li></ul><ul><li>Enables you to manage the process as a complete system </li></ul>
  4. 4. DCS Architecture Instruments, sensors, and actuators PLCS and local control loops Data Acquisition and Interface Control rooms and SCADA Internet Remote access
  5. 5. Types of DCS <ul><li>Several types, like: </li></ul><ul><ul><li>Smart DCS </li></ul></ul><ul><ul><li>SixTrak IPm </li></ul></ul>
  6. 6. Smart DCS <ul><li>Developed by Honeywell’s MICRO SWITCH Division </li></ul><ul><li>Advanced industrial control system that’s open at both the controller and device levels to maximize freedom of choice for users </li></ul><ul><li>can interface with both PC controllers and PLCs </li></ul>
  7. 7. Smart DCS <ul><li>Some applications: </li></ul><ul><ul><li>Food processing equipment </li></ul></ul><ul><ul><li>Material handling </li></ul></ul><ul><ul><li>Conveyor Systems </li></ul></ul>
  8. 8. SixTrak IPm <ul><li>A powerful DCS controller based on flexible open standards and packed with a wealth of features that only LINUX can provide such as: </li></ul><ul><ul><li>Internet & internal Intranet Accessible by The SIXNET I/O Tool Kit </li></ul></ul>
  9. 9. Choosing DCS systems <ul><li>Reliability </li></ul><ul><li>Compatibility and operatibility </li></ul><ul><li>Graphical interface </li></ul><ul><li>Control algorithms (PID, ON-OFF, Fuzzy, Neural networks, etc.) </li></ul><ul><li>Processing speed and cycle time </li></ul><ul><li>Ease of configuration </li></ul><ul><li>Ease of use </li></ul><ul><li>Support and upgradeability </li></ul><ul><li>Cost </li></ul>
  10. 10. Network Configuration <ul><li>Configuration: Geometric physical form of the connections of the nodes and links of the network </li></ul>
  11. 11. 1. Star <ul><li>All communication is through the central unit </li></ul><ul><li>If central unit failed, all network will fail </li></ul><ul><li>Lots of wiring </li></ul><ul><li>Full control of data flow </li></ul>
  12. 12. 2. Ring <ul><li>Any node can have a direct contact with other </li></ul><ul><li>No two nodes can send at the same time (o.w. there will be a collision) </li></ul><ul><li>If one node fails, all network will fail </li></ul><ul><li>Data sender/receiver are distinguished by the addresses. </li></ul>
  13. 13. 3. Bus <ul><li>All nodes have a direct connection with each other </li></ul><ul><li>Failure of nodes doesn’t affect the network </li></ul><ul><li>New nodes can be easily added </li></ul><ul><li>Data sender/receiver are distinguished by the addresses. </li></ul>
  14. 14. Properties of distributed systems <ul><li>Robust </li></ul><ul><li>Flexible </li></ul><ul><li>Secure </li></ul><ul><li>Emergent behavior </li></ul><ul><li>Less expensive installation and better reliability. </li></ul><ul><li>Less expensive to expand . </li></ul><ul><li>Data highway is used to replace wire from sensor to DCS and to the control valve. </li></ul><ul><li>It could do analog and discrete control. </li></ul>
  15. 15. Disadvantages: <ul><li>Component cost </li></ul><ul><li>A distributed system can be somewhat difficult to maintain </li></ul><ul><li>Programming them is not easy </li></ul><ul><li>Computing power per node is limited </li></ul>
  16. 16. Some manufacturers of the DCS: <ul><li>Honeywell </li></ul><ul><li>ABB Control, Inc. </li></ul><ul><li>Eaton Electrical, Inc. </li></ul><ul><li>Mitsubishi Electric Automation, Inc. </li></ul><ul><li>Phoenix Contact, Inc. </li></ul><ul><li>Rockwell Automation </li></ul><ul><li>Schneider Automation, Inc. </li></ul><ul><li>Siemens Energy & Automation, Inc. </li></ul><ul><li>Square D Company </li></ul><ul><li>WAGO Corporation </li></ul>
  17. 17. Companies in Saudi Arabia that uses DCS <ul><li>SAUDI ARAMCO </li></ul><ul><li>Ghazlan Power plant </li></ul><ul><li>SABIC </li></ul><ul><li>Almost all factories in Jubail and Yanbu </li></ul>
