Abstract: As we all know that energy consumption has increased a lot and sources of energy are limited, it has become mandatory to conserve power. Energy crisis is one of the critical issues. The street lighting is one of the largest energy expenses for the city, accounting for upwards of 35-45% of a municipality’s utility budget. An intelligent lighting control system can reduce municipal street lighting costs as much as 70%. The main aim of the proposed system is the intelligent gleam control of street lights using PIR sensor to optimize the problem of power consumption. Street lights are being replaced by LED’s and controlled by Programmable Logic controller (Siemens S7-200 PLC). The main difference from other controllers is that PLC’s are toughened for severe conditions and have the feature for extensive input/output (I/O) arrangements. This system can save a large amount of electricity compared to the existing one.

Abstract— As the world is globalized day by day, so the demand of automated machines has increased rapidly. In industry or any power plant boiler hold a significant contribution. To control it industry need uninterrupted monitoring at frequent interim. But there have number of restriction to measure various stage of boiler by worker. In this paper there has been designed and implemented an automated boiler control system using programmable logic control system (PLC) to exceed respective errors. The main operation of this project is to start and stop boiler system automatically according to set value. There has used sensor to measure the temperature and control it by sending this signal to PLC. Moreover, the boiler system can run for a certain period using the ON-OFF push button.

Abstract— This paper presents real time control of process through Programmable Logic Controller using SCADA and MATLAB OPC Toolbox. It uses KEPServerEX.V4 from Kepware technologies as OPC DA Server that works on server client architecture. In this SCADA and MATLAB are acting as clients. The design and implementation is carried in three phases. In the first phase PLC based application has been designed, and then SCADA application were developed and integrated with process through OPC server. Finally, MATLAB SIMULINK model is designed for accessing real time process data. The realization of the test system has been validated using Mitsubishi FX2N 32MR PLC, CitectSCADAv2 and MATLAB. The control of process and results of test system show efficient and reliable exchange of real time data between PLC, MATLAB and SCADA.

Abstract—This paper presents CLIK, a new remote attack on the control logic of a programmable logic controller (PLC) in industrial control systems. The control logic defines how a PLC controls a physical process such as a nuclear plant. A full control logic attack faces two critical challenges: 1) infecting the control logic in a PLC at a field site and, 2) hiding the infection from engineering software at a control center since the software can obtain the infected logic from the PLC and reveal it to a control engineer. The existing academic efforts only (partially) address the former. CLIK is a first practical control-logic attack that deals with both challenges successfully. It modifies the control logic running in a remote target PLC automatically to disrupt a physical process. CLIK also employs a new virtual PLCapproach that hides the malicious modifications by engaging the engineering software with a captured network traffic of the original (uninfected) control logic. It is fully implemented on real hardware/software used in industrial settings and is made publicly available for academic research on control logic attacks1. CLIK consists of four phases and takes less than a minute to complete an attack cycle. As part of the implementation, we found a critical (zero-day) vulnerability in the password authentication mechanism of a target PLC, which allows the attacker to overwrite password hash in the PLC during the authentication process and gain access to the (protected) control logic. We have disclosed the vulnerability responsibly to the PLC vendor who has already patched the vulnerability

Abstract: In this advance era, automatic sorting is highly desirable in approximately every industry. Its main objective is to reduce human efforts and time which can ultimately raise its efficiency. However, perfect sorting machine is still in progress which should be flexible and compatible in design. In this work, the proposed sorting machine is able to corporate compatibility by using conveyer belt and proximity sensors to detect type of material i.e. wood, metal or plastic and also identifies size of material in three different ranges and finally sort the material separately in assigned basket by using pneumatic cylinder (controlled by Programmable Logic Controller (PLC)). The proposed multi sorting system is able to sort nine objects of nine different ranges are sorted with 100% accuracy within the time interval of 0.5 seconds. The proposed model could be implemented in any industry whose applications are mechatronics based engineering system. This model can also produce list of sorted objects through enabled sorting program commands.

Abstract - In the previous 20 years transformer warming is a noteworthy issue in creating station, substation, circulation locale and different territories. The primary driver of overheating are Insulation overheating, Corona overheating, Liquid overheating, Arcing is overheating, screen testing overheating. Because of this it causes numerous issues, for example, Coil harm, bursting of transformer, Block of wind, and so forth. To lessen the warmth which is created from the transformer, to trip the transformer when it is in over warmth condition and the stop the absolute circuit for upkeep period a we have built up this task dependent on Programmable Logic Controller.

ABSTRACT The proposed system provides an analysis of simulation and components required for the anti-corrosion process with the help of the PLC (Programmable Logic Controller). In this paper, automation control process is carried out for anti-corrosion purpose. The manual process is very complicated and time consuming.

The complex motor system is composed of a DC motor, driver & a tachogenerator. The main objective is to achieve a satisfactory time response of the system output under external load acting. The PI controller is designed in the programming environment on a previously identified non-linear motor system. Then the PI controller is embedded in the Programmable Logic Controller. Finally the effectiveness of the controller is tested in both simulation mode & experiments.

Automation can be defined as the technology by which a process or way is performed without human succor. automatic control, is the use of various control system for operating equipment such as machinery, processes in industries, boilers and electrostatic precipitator, switching on communication networks, navigation and stabilization of ships, aircraft and other applications and vehicles with trifling human intervention. Some processes have been completely automated. The motor speed is controlled via the driver as an open loop control system. To make a more accurate closed loop control of motor speed we will use a tachometer (revolution-counter, tach, rev-counter, RPM gauge) to measure the speed and feed it back to the PLC, which compares to the desired value and take a control action, then the signal is transferred to the motor – via driver – to increase / decrease the speed. We will measure the speed of the motor using an incremental rotary encoder by adjusting parameters (PLC, driver) and also, we need to reduce the overall cost of the system. Our control system will be held using the available Siemens PLC. In addition, we will monitor motor parameters via SCADA system.
