Question
Chapter 12, Problem 4RQ
Program Plan Intro
a.
Programmable Logic Controller (PLC):
- Programmable Logic Controller (PLC) is a specialized computer used in industrial segments to control machines and process.
- PLC is program that consists of a set of instructions which 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.
Sequencers:
- PLC sequencer performs ON or OFF output patterns using sequencer instructions.
- The sequencer output instruction is used for controlling the output devices.
- PLC sequencer instructions are used for controlling machines which provides a stepped sequence of repeatable operations.
- It simplifies the ladder program by allowing the user to use a single or pair of instructions for performing complex operations.
- Various sequencer instructions can be programmed based on the PLC manufacturer.
