This study is about the development of a control system design using Programmable Logic Controller (PLC) system which gives food to the fish with a blower method. To perform fish feeding system automatically the control system will include PLC system, touch screen, emergency button, terminal block, speed controller, relay NY-2N, and power supply 240V. The component of the input systems are auto...

As a result of the production powder processing causes lot dust around machine and factory. This course can cause pollution. Dust needs to be collected using Collector (DC) machine. The controller on DC at PT. xxx is often damaged in control unit requires repairs cost Rp. 5,000,000 per unit. In facts there are about 10 units machines PT.xxx that must work all. Because their controllers, mainten...

Theproposed system provides an analysis of the simulation and components required for the implementation of an automated level control system by the help of Programmable Logic Controller (PLC).Supervisory Control And Data Acquisition(SCADA) was established and the HMI was created. The proposed model can effectively supervise level control in multiple tanks. Three level sensors were used to prov...

A boiler plays a significant role in processing industry, particularly chemical industry. It requires proper adoption of control techniques for supplying accurate temperature, pressure, steam, and water flow to produce chemicals. An uncontrolled can shut down the whole process. Therefore it continuous monitoring system avoiding such shutdown. In past few decades, relay logic, embedded or proces...

In this article, we present an implementation of a low-memory footprint model predictive control (MPC)-based controller in programmable logic controllers (PLCs). Automatic code generation standardized IEC 61131-3 PLC programming languages is used to solve the MPC's optimization problem online. The designed for its application realistic industrial environment, including timing considerations and...

Programmable logic controllers are the main controllers in the today’s industries; they are used for several applications in industrial control systems and there are lots of examples exist from the PLC applications in industries especially in big companies and plants such as refineries, power plants, petrochemical companies, steel companies, and food and production companies. In the PLCs there ...

We present an algorithm for synthesizing real-time controllers specified in a subset of the interval temporal logic duration calculus. The synthesized controllers are given in terms of programmable logic controller (PLC)-automata, which are an abstract description of programs of polling machines. PLCautomata can be implemented directly on PLC’s, a special kind of polling real-time controllers t...

Among all kinds of possible faults in a manufacturing system, operational faults occur most often (about 70%). Efficient diagnosis of these faults is critical for improving the availability and productivity of the manufacturing system. This paper presents a hierarchical diagnosis model based on fault tree analysis and two other diagnosis models respectively based on the logic and sequential con...

This paper deals with the identification of discrete event manufacturing systems that are automated by a programmable logic controller (PLC). The behaviour of the closed loop system (PLC and Plant) is observed during its operation and is represented by a single long sequence of observed input/output signals vectors. The proposed method follows a blackbox and passive identification approach; it ...
