Overview

PROGRAMMABLE LOGIC CONTROLLERS – PLC

Course Outcome

4 Modules

The complete course consists of 4 video modules and 2 PDF manuals which include self-assessment

Module 1 – Fundamentals of Automatic Control

At the end of this module learners will be able to:

  • Identify the 3 basic stages of a typical automatic control system
  • Describe the operation of a two state switch and a two state logic
  • Explain the operation of a two state relay, and describe the function as a control device
  • Explain the basic differences between a relay logic controller and a programmable logic controller

Module 2 – Relay Logic Devices & Ladder Diagrams

At the end of this module learners will be able to:

  • Identify typical symbols in relay ladder logic diagrams
  • Identify typical input, logic and output devices
  • Describe typical circuit operation from a ladder logic

Module 3 – PLC Hardware & Ladder Logic

At the end of this module learners will be able to:

  • Describe the purpose and function of I/O’s
  • Decipher address locations and devices involved in PLC ladder logic diagrams
  • Describe how a CPU processes input signals to control the state of outputs
  • Explain the basic differences between a relay logic controller and a programmable controller

Module 4 – The PLC as an Information Processor

At the end of this module learners will be able to:

  • Describe how the PLC processes information by a process called SCAN
  • Describe the basic operation of the CPU and its memory circuits
  • Describe the internal logic devices that exist in the virtual world of the PLC
  • Explain the operation of contacts, coils, timers and counters that appear in a typical PLC ladder logic diagram
