Introduction
The 20th century was the period that companies built the rich lives through the mass production, bulk consumption and destruction. The 21st century is the period that the environment and industrial revolution live together with our conscious of environmental problem caused from those results. This is the word our president ....etc

PLC BASED DOOR OPEN AND CLOSE SYSTEM



WORKING PRINICIPLE:
The microcontroller based Door locker is an access control system that allows only authorized persons to access a restricted area. The system is fully controlled by the 8 bit microcontroller PLC. The password is stored in the EPROM so that we can change it at any time. The system has a Keypad by which the password can be entered through it. When the entered password equals with the password stored in ....etc

in this project PLC is used to control the flow of lubricating oil at specified level , this can be done to on bearing, journals and other engine part by installing a transducer near to it , automatically controlling the lubrication of a bearing can be performed either by a stationary installed vibration servo or by measuring the real amount of grease being fed into the bearing . The figure shows a flow transducer unit installed directly in to the grease point. The unit closes/opens a switch which can be used to monitor the real grease flow. ....etc

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

CHAPTER 1
INTRODUCTION
A traffic light is a collection of two or more coloured lights found at some junctions and pedestrian crossings which indicates whether it is safe and/or legal to continue across the path of other road users. In the United Kingdom, traffic lights are widely used both on major roads and in built-up areas. Their numbers have increased exponentially since they were first invented in 1868.
The operation of standard traffic lights which are currently depl ....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
