This paper presents a design and implementation of a monitoring and control system for the three-phase induction motor based on programmable logic controller (PLC) technology. Also, the implementation of the hardware and software for speed control and protection with the results obtained from tests on induction motor performance is provided. The PLC correlates the operational parameters to the ...

reversible logic circuits have found emerging attentions in nanotechnology,optical computing, quantum computing and low power design. a programmablelogic array (pla) is a universal circuit which is used to implement combinationallogic circuits. the main part of a pla is its and array. in this study we propose twotypes of optimized reversible programmable logic array (rpla) circuits. the firstty...

With the explosive growth of data at edge in Industrial Internet Things (IIoT), devices are increasingly performing more processing tasks to alleviate load on cloud servers. To achieve this goal, Programmable Logic Controllers (PLCs) gradually transitioning into PLCs. However, efficiently executing a large number computational memory-limited PLCs is significant challenge. Therefore, there need ...

In this paper, the application of the Hierarchical Interface-based Supervisory Control method to controlling a large scale manufacturing example is presented adopting a layered organizational hierarchy of a factory. The generic and easily maintainable implementation using programmable logic controllers, a personal computer and TCP/IP over Ethernet for communication is explained in detail. To as...

M achinery controls have evolved from simple hardware circuits to ever more complex hardware and software systems. Although still used, relays have been supplanted by programmable logic controllers (PLCs) and more recently safety-rated PLCs. Control systems use increasingly sophisticated complex integrated circuits, microprocessors and firmware. This has allowed great advancements in many respe...

In this paper we present a new tool for editing, visualizing, and implementing Signal Interpreted Petri Nets (SIPNs). SIPNs are used to formally specify control algorithms for Programmable Logic Controllers (PLCs). The presented tool allows to automatically transform a graphically edited SIPN into PLC code using the standardized PLC language Instruction List. The tool was implemented using DiaG...

Sequential function charts are a popular formalism to specify programmable logic controllers. However, in the absence of the controlled system, verification of sequential function charts can only consider the controller’s behavior, but cannot tell anything about the controlled system. In this paper we propose an extension of the language to additionally model the continuous dynamics of the cont...

Artists continue to search for new methods of creation of artworks. The trend to interactive multimedia installation work requires systems that allow participants to interact in subtle ways. The paper describes a number of non-conventional interfaces to computer mediated art works achieved using small Programmable Logic Controllers (PLC) called ‘Stamps’. These are programmed in BASIC and can be...

Moby/plc is a graphical design tool for PLC-Automata, a special class of hierarchical real-time automata suitable for the description of distributed real-time systems that are implementable on a widely used hardware platform, so-called Programmable Logic Controllers (PLCs). In this paper we sketch the modelling language in use and some features of Moby/plc, like several validation methods and c...

Programmable Logic Controllers (PLCs) have been used to control industrial processes and equipment for over 40 years, having their first commercially recognised application in 1969. Since then there have been enormous changes in the design and application of PLCs, yet developments were evolutionary rather than radical. The flexibility of the PLC does not confine it to industrial use and it has ...
