The implementation of a low-cost FATEK PLC-based three-floor lift system is described in this study. Elevator systems are critical for vertical mobility buildings, and their control methods have been revolutionized by the use programmable logic controllers (PLCs). To motion lift, we DC geared motor. In example, push buttons used to direct elevator desired floor. scenario, ladder diagram program...

The task of safeguarding systems is to bring processes from dangerous into safe states. A special class of safeguarding systems are emergency shutdown systems (ESD), which, until now, are only implemented in inherently fail safe hardwired forms. Despite their high reliability, there is an urgent industrial need to replace them by more exible systems. Therefore, in an earlier work, a dedicated p...

Under the present regime of globalization and liberalization, quality enhancement and cost reduction are two major steps to enhance productivity in major Industries. We focused on the very practical, safe, economical and rewarding strategies i.e. the application of LOW COST AUTOMATION. In Industry which uses of automation, a sequence is followed in the manufacturing of number of products of the...

High availability interlocks and controls are required for the ILC (International Linear Collider) L-Band high power RF stations. A new F3 (Fast Fault Finder) VME module has been developed to process both fast and slow interlocks using FPGA logic to detect the interlock trip excursions. This combination eliminates the need for separate PLC (Programmable Logic Controller) control of slow interlo...

Many industrial companies and researchers are looking for more efficient model driven engineering approaches (MDE) in software engineering of manufacturing automation systems (MS) especially for logic control programming, but are uncertain about the applicability and effort needed to implement those approaches in comparison to classical Programmable Logic Controller (PLC) programming with IEC 6...

This paper describes the application of an adaptive predictive expert (ADEX) control solution to the attemperation process for superheated steam temperature control in the ScottishPower coal-fired power station at Cockenzie near Edinburgh in Scotland. The project comprised two phases, the first of which was a trial to establish the feasibility and potential benefits of ADEX compared with the ex...

We report on the use of the SPIN model checker for both the veri cation of a process control program and the derivation of optimal control schedules. This work was carried out as part of a case study for the EC VHS project (Veri cation of Hybrid Systems), in which the program for a Programmable Logic Controller (PLC) of an experimental chemical plant had to be designed and veri ed. The intentio...
