Programmable Logic Controller based on reconfigurable logic

2009 15th International Symposium for Design and Technology of Electronics Packages (SIITME), 2009
The paper presents an idea of a Programmable Logic Controller for binary control implemented in an FPGA device with use of custom designed implementation tools. It is an extension of previously proposed architecture that is mainly limited by hardwired connection. Based on connection resources available in FPGA the new architecture is proposed. Possible

Simulation of programmable logic controller

Computers & Industrial Engineering, 1992
Abstract The development and test of a PLC control program takes time, increases equipment down-time, and might damage hardware due to program errors. All of these problems can be eliminated if there is a computer simulation system for testing control programs off line.

Modeling programmable logic controllers for logic verification

IEEE Control Systems, 1994
Verification method has been developed for determining the safety and operability of programmable logic controller (PLC) based systems. The method automatically checks sequential logic embedded in PLCs and provides counterexamples if it finds errors. The method consists of a system model, assertions, and a model checker.

Programmable logic controllers

The technical means that have now become the basic ones for building modern process control systems, such as programmable logic controllers, are considered. Section I consistently outlines the structural and architectural principles of controller design and operation, and provides an overview of devices available on the foreign and domestic market ...

Virtualization of programmable logic controllers

Eletrónica e Telecomunicações, 1999
Programmable Logic Controllers (PLC) are widely used in industry, This implies that more and more people must be trained in order to obtain enough knowledge to develop, mantain and upgrade applications involving PLCs, from simple motor commands to sophisticated process controllers. (...)
