i am rahul yadav btech electrical engg. final year.
i have got the project on topic Design of plc based process control system.
i have got the problem statement but i am facing the difficulty in implementing it.
problem statement is: To make a ladder logic program for controlling the motion of conveyors used in packaging industries used for packing products in boxes kept on conveyor.The conveyor has to stop with certain time delay till the product gets filled in the box. if the box is not filled in that duration then it should ....etc

AUTOMATIC TEMPERATURE CONTROL IN VACUUM BRAZING FURNACE USING P.L.C

ABSTRACT
The main objective of this project is to maintain & control temperature uniformly of the two zones in vacuum brazing furnace and braze similar or dissimilar components using certain chemicals, for the given specifications of a job
Brazing alloys used for brazing the components of gas turbines and aerospace applications contain nickel as the base material. Nickel has highest affinity for oxygen. Incase if components are brazed using nickel ....etc

I. INTRODUCTION
Over the years the demand for high quality, greater efficiency and automated machines has increased in the industrial sector of power plants. Power plants require continuous monitoring and inspection at frequent intervals. There are possibilities of errors at measuring and various stages involved with human workers and also the lack of few features of microcontrollers. Thus this paper takes a sincere attempt to explain the advantages the companies will face by im ....etc

Introduction
Traffic signals are the most convenient method of controlling traffic in a busy junction. But, we can see that these signals fail to control the traffic effectively when a particular lane has got more traffic than the other lanes. This situation makes that particular lane more crowdy than the other lanes. If the traffic signals can allot different time slots to different lanes according to the traffic present in each lane, then, this problem can be solved easily.
We, in this project work, i ....etc

Control of Boiler Operation using PLC – SCADA
Abstract––This paper outlines the various stages of operation involved in the conversion of a manually operated boiler towards a fully automated boiler. Over the years the demand for high quality, greater efficiency and automated machines has increased in this globalised world. The initial phase of the paper focuses on passing the inputs to the boiler at a required temperature, so as to constantly maintain a particular temperature in the boiler. The Air preheater and Eco ....etc

PLC-Based Monitoring Control System for Three-Phase Induction Motors
The article presents a monitoring and control system design and implementation for the three-phase induction motor based on programmable logic controller (PLC) technology. the operational parameters of the motor is correlated with the the speed requested by the user by the PLC. This is done in both the during normal operation and under trip conditions. Tests prove that a higher accuracy in speed regulation is provided by the induction motor system driven by inverter a ....etc
