This paper is presented to introduce a system constituting of a PLC (Programmable Logic Controller) that is connected to the level switches which is monitoring the level of the tank. This system saves the tank from over flowing which increases the safety and efficiency. The levels are considered as an input to the PLC and the pump is controlled by the output of PLC which pumps out the solvent or any...
HTML5 [1] has been recently evolution in web technologies which enables user to create web based control system user interfaces (UI). These user interfaces can work on cross browser and cross device compatible. Control system studio (CSS) Operator Interfaces (OPI) allow user to create user interfaces with drag and drop fashion. These developed interfaces developed in CSS BOY[2] can be seamlessly display...
Today, in most automatic process control applications in industry are used PID controllers. It is very important for the students to understand how work these controllers and how important it is to make an optimal tuning of these controllers. This paper presents a solution which permits to study and understand PID controllers. This solution is a closed-loop speed control system in a centrifugal load...
The present paper intends to highlight the utility and importance of programmable automates in the control of the industrial processes. The paper presents the programming of a Siemens CPU 313C PLC in Ladder Diagram language and the making of a graphical interface for an interactive simulation with the help of a touch screen HMI of a concrete plant. The application allows the control and the simulation...
Inertia drivers, for a power plant are High Tension drives (HT Drives) / Drive turbines. Various machine parameters are acquired into the DCS (Distributed Control System)/PLC (Programmable Logic Controller) for monitoring / interlock / protection. Winding and Bearing temperature signals are acquired into the DCS/PLC as RTD signals. Higher plant uptime with reduced spurious tripping of HT Drives is...
In order to access a high level processing, scalability and reliability, one needs to process machine level data in high level data processing and makes a connection between them (make them coherent). This paper is intended to monitor Delta PLC 14SS in .NET frame work, c#, by monitoring a glazier machine, it is aimed to describe how to address and to access inputs, outputs and memories of PLC which...
The current situation of environmental resources requires their efficient usage through efficient process control. But, process control can not be achieved without an essential component: the communication between all devices, such as sensors, controllers, actuators, programming stations etc. The aim is to achieve the irrigation process of plants in greenhouse conditions. Therefore, it is submitted...
