Introduction
In past, human was the main method for controlling a system.
More recently electricity is used for control and earlier electricity control is based on relays.
The development of low cost computer has brought the most recent revolution.
PLC is a work house of industrial automation.It is important because all production process go through a fixed repetitive sequence of operation that involve logic step and de ....etc

Introduction

In the fast developing world, height of the buildings increased tremendously and the lift has become more of a necessary rather than luxury. When the number of floor increased the control mechanism required for the lift will become more complex. Programmable Logic Controllers are widely accepted industrial control device. With the growth in technology PLCs are now capable of advanced data manipulations, communications ....etc

1. INTRODUCTION
Programmable logic controllers (PLCs) are members of the computer family capable of storing instructions to control functions such as sequencing, timing, and counting, which control a machine or a process. The PLC is composed of two basic sections, the Central Processing Unit (CPU) and the Input/Output (I/O) interface system. The PLC measures input signals coming from a machine and through the internal program provides output or control back to the machine.
Ladder logic is the programming language used t ....etc

INTRODUCTION :-

PLC is a digitally operating electronic apparatus which uses a programmable (through dedicated language such as Relay Ladder Programming) memory for the internal storage of instructions for implementing specific functions such as logic, sequencing, timing, counting and arithmetic to control through digital or analog input output modules, various types of machines and processes.
The programmable controllers (PC) have developed as the heart of the automation of the industries. The PCs offer a number of advantages over th ....etc

ABSTRACT
Development of a traffic light control system using PLC (Programmable
Logic Controller) is the title of this project. This project is divided into two parts
which are hardware and software. The hardware part for this project is a model of
four way junction of a traffic light. Each lane has two limits switch (input) function
as a sensor. Three indicator lamps with different colours (Red, Yellow and Green)
are installed at each lane for represents as traffic light signal. This limit switches and
indicator lamps are connect ....etc

COMPLEX PROGRAMMABLE LOGIC DEVICE


As chip densities increased, it was natural for the PLD manufacturers to evolve their products into larger (logically, but not necessarily physically) parts called Complex Programmable Logic Devices (CPLDs). For most practical purposes, CPLDs can be thought of as multiple PLDs (plus some programmable interconnect) in a single chip. The larger size of a CPLD allows we to implement either more logic equations or a more complicated design. In fact, these chips are large enough to replace dozens of the pesky p ....etc
