Ai 150 architecture

  1. 1. Industrial Automation Automation Industrielle Industrielle Automation Control System Architecture 1.5 Architecture de Contrôle - Commande Leittechnik-Architektur Prof. Dr. H. Kirrmann ABB Research Center, Baden, Switzerland2012 February, HK
  2. 2. 1.5 Control System Architecture1 Introduction 1.1 Automation and its importance 1.2 Applications of automation 1.3 Plants and controls 1.3.1 Open loop and closed loop control 1.3.2 Continuous process 1.3.3 Discrete process 1.3.3 Dual plants 1.4 Automation hierarchy 1.5 Control System Architecture Industrial Automation Control System Architecture 1.5 - 2
  3. 3. PrincipleThe control system is a communication system consisting of controllers and links.The structure of the control system should reflects that of the plantIdeally, each unit of the plant should have its own controller,interacting with the controllers of the other, related units,mirroring their physical interaction.Example: Airbus: a wing is delivered with its own computers. Industrial Automation Control System Architecture 1.5 - 3
  4. 4. Example: Power plant control - 1980 (!)Control systems look similar Industrial Automation Control System Architecture 1.5 - 4
  5. 5. Busses and processors in industrial plants instrument bus (mimic board) open network, WAN Operator panel disk Mimic board Process pictures Process Data Base workstation bus Logging station station plant network (500m .. 3 km) – includes control networkprocessor pool P P P C P P C P PLC nodes node bus (multi-processors) I/O MEM I/O MEM BC fieldbus (30m..2 km) directly coupled control backplane bus input/ stations output sensor bus sensor bus (0,5.. 30 m) transducers M plant (Werk, usine) valve thermo-couple position motor Industrial Automation Control System Architecture 1.5 - 5

  16. 16. Centralized (Hierarchical) Control Architecture Central Computer (Mainframe) Group Group Group PLCs Control Control Control Sensors, Actors plantClassical, hierarchical, centralized architecture.The central computer only monitors and forwards commands to the PLCs Industrial Automation Control System Architecture 1.5 - 16
  17. 17. Decentralized Control System (DCS) hierarchical(vertical communication) engineering operator data logger workstation workstation peer-to-peer (horizontal communication) plant bus controller controller controller controller field bus plant all controllers can communicate as peers (without going through a central master), restricted only by throughput and modularity considerations. Note: Honeywells "DCS™" stands for "Distributed Control System", it is not a decentralized control system, but a control system for the process industry.

  19. 19. Hierarchies aresimple and traditional Industrial Automation Control System Architecture 1.5 - 19
  20. 20. but Distributed ControlSystems reflects a more complex world.... Industrial Automation Control System Architecture 1.5 - 20
  21. 21. Assessment1. Draw a typical hierarchical control system showing busses and controllers2. How does the network hierarchy relate to the plant control hierarchy ?3. What is the difference between a centralized and a decentralized control system ? (can this difference be seen from the outside ?) Industrial Automation Control System Architecture 1.5 - 21
