In this program, you will be introduced to programmable logic controllers (PLCs) and how they are used to implement electrical and motor control circuits in industrial applications. This module explains how a PLC operates and the important relationship between electromechanical and PLC ladder diagrams.

The program also covers the important topic of I/O field device addressing and how field devices are known inside the PLC. Discrete input and output interfaces are discussed as well as how to install them and the actual PLC unit.

Thoroughly explained are the discrete programming instructions that are used in the implementation of electromechanical control using a PLC, which are the basic relay instructions. The operation of the basic on-delay and off-delay types of timers and how to program them in a PLC application is also addressed as well as the special considerations that you must take when implementing timer control programming.

You are presented with the implementation of PLC control from electromechanical control. The examples involve the control of motors as well as the implementation of Forward/Reverse control using a Fwd/Rev motor starter.

Explanations on how to go about to assign the input and output addresses that will be used in the PLC are presented. Also covered are the troubleshooting of PLC inputs and outputs as well as the CPU and how to implement basic PLC preventive maintenance.​

PLCs—What Everyone Needs to Know

  • Understanding PLCs will make your job easier.
  • Is your PLC system safely and properly installed—learn which sections of the control circuit must be left hardwired for safety reasons.
  • Now you will know why PLC use different number systems.
  • Understand PLC ladder symbology and power flow: continuity & logic.
  • Implement motor circuits (2-wire & 3-wire control), wiring and interfacing to magnetic starters, reversing motor control and interlocking.
  • Learn the PLC software instructions to convert an electromechanical (hardwired) system to a PLC-based system.
  • Know how to avoid possible timer control problems.
  • Trap the right timer contact in an electromechanical circuit during a PLC implementation.
  • If you're using PLCs to control motors, make sure you're implementing low-voltage protection—we'll show you how and help you avoid potential injury to personnel and equipment.
  • One small wiring mistake during troubleshooting will make things worse—we'll show you the right way to do it step-by-step.
  • Follow our step-by-step method of converting a hardwired relay system to a PLC-based system—do it quickly and do it right!
  • Troubleshoot the complete discrete I/O system—see it graphically—from power line problems to wiring connections to I/O modules to the detection of a bad field device.
  • Quickly pinpoint the problem is with the controller, the wiring, or a field device.
