ABSTRACT : One of the challenging factor in factories, for the proper functioning of the machine for the long duration with efficiency is to keep certain parameters within a specific range. Thus, in this paper, we have designed a ladder diagram for running PLC with the objective to automatically control the hydraulic system. Our main requirement is to design a PLC which can be connected to hydraulic system to implement the parameters and operations like Temperature detection, Pressure detection, Lubrication, Automatic machine operation and Oil level detection. The mentioned parameters and operations can be sensed and operated through PLC without any manual checking and operation. This saves more power to industries by reducing the power consumption.

INTRODUCTION In the last decades, the machines used in the industries were operated manually. So keeping its certain important parameters in a specific range was difficult. Also they can not be checked out frequently. This results in improper functioning of the machine. Also, the machines cannot work efficiently for a long time. For example, if the temperature of the oil goes beyond the desired value it will affect the machine function. Hence the machine accessories cannot withstand this high temperature. This leads to the damage in machine and the durability of the machine also gets reduced.

    Next plc designs, manufactures, and distributes clothing and home furnishing and accessory items to nearly 330 Next retail stores and through the company 's Next Directory mail order sales catalog. Almost all of Next company-owned stores are located in England and Ireland. After ending a brief international expansion--in 1999 the company closed its seven company-owned foreign stores, including its five U.S. retail stores--Next has shifted its international strategy to brand expansion focused on franchising. Next operates franchises in some 20 international markets, especially in the Middle Eastern and Far East Asian markets. The difficult economic climate in the Asian markets in the late 1990s has curtailed the Next franchise expansion, however; after building to 43 franchised locations by 1998, the company entered 1999 with just 35 franchise stores.…

    There are 3 types of PLC, unitary, modular and rack-mounted. A unitary PLC is a stand alone unity, it has no room for expansion and works on its own. They are useful for automating activities such as stress testing. For example the stress testing of a hoist, instead of paying someone to manually control the hoists up and down movement leaving time in between each motion a PLC could be used instead. It could be set up to perform a number of cycles of movement of the hoist by the use of limit switches at the top and bottom of its movement to detect when to change direction. The time to wait between movements can be set so that the motor doesn't get strained. Other safety features could be added, for example, a set of sensors could be installed around the hoist to stop it's movement if some one comes too close to it. It would also be easier to set the parameters of the test and change them easily for testing a different hoist or piece of equipment. It would have to keep its functionality to a small scale as it can't be upgraded at all. A large variety of inputs and outputs could be used as most PLCs support analogue and digital. This would mean you could have temperature sensors in use on the analogue and through-beam sensors on digital. It is likely that this type of PLC would be mounted somewhere near the object it is controlling, most likely to a nearby wall.…

    [PID] FundamenInstrumentation and process control can be traced back many millennia. Some of the early examples are the process of making fire and instruments using the sun and stars, such as Stonehenge. The evolution of instrumentation and process control has undergone several industrial revolutions leading to the complexities of modern day microprocessor-controlled processing. Today’s technological evolution has made it possible to measure parameters deemed impossible only a few years ago. Improvements in accuracy, tighter control, and waste reduction have also been achieved.…
