advanced plc development

Technological advances in recent years have resulted in the development of the programmable logic controller and a consequential revolution of control engineering.

This website covers :-

  • The basic architecture of PLCs and the characteristics of commonly used input and outputs to such systems.
  • A painstaking methodical introduction, with lots of illustrations, of how to program PLCs, whatever the manufacturer, and make use of internal relays, timers, counters, shift registers, sequencers and data handling facilities.
  • Consideration of the standards given by IEC 1131-3 and the programming methods of ladder, functional block diagram, instruction list, structured text and sequential function chart,
  • To assist the visitor to develop the skills necessary to write programs for programmable logic controllers, many worked examples, multi-choice questions and problems are included.

Aims

This website aims to enable the reader to:
  • Identify and explain the main design characteristics, internal architecture and operating principles of programmable logic controllers.
  • Describe and identify the characteristics of commonly used input and output devices.
  • Explain the processing of inputs and outputs by PLCs.
  • Describe communication links involved with PLC systems, the protocols and networking methods.
  • Develop ladder programs for the logic functions AND, OR, NOR, NAND, NOT and XOR.
  • Develop ladder programs involving internal relays, timers, counters, shift registers, sequencers and data handling.
  • Develop functional block diagram, instruction list, structured text and sequential function chart programs.
  • Identify safety issues with PLC systems.
  • Identify methods used for fault diagnosis, testing and debugging.
