Chapter 14, Problem 18RQ

Program Plan Intro

Programmable Logic Controller (PLC):

• PLC is a specialized computer used in industrial segments to control machines and process.
• PLC is program that consists of a set of instructions that resembles the controlling functions needed to perform specific tasks.
• The function of PLC is similar to that of a relay and hence, in an industrial segment a relay is greatly replaced by a suitable PLC.
• When compared to general Personal Computer (PC), a PLC is available in small and tiny sizes.
• The basic architecture of a PLC consists of an input-output interface module and a small Central Processing Unit (CPU) that runs by controlling programming language.

Motion Control:

• A motion control system is used to provide accurate positioning, velocity, and torque control for a variety of motion applications.
• A basic PLC motion control system includes a programmable controller, motion module, servo drive, servomotor, and the machinery being controlled.
• An axis of motion refers to each motor controlled in the system.
