Download or read book A Safety Licensable Computing Architecture written by Wolfgang A Halang and published by World Scientific. This book was released on 1993-12-30 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the design of a low complexity, fault-detecting computer architecture for utilisation in programmable logic controllers (PLCs) for process control purposes. The cyclic operating mode of PLCs and a specification level graphical programming paradigm based on interconnecting application-oriented standard software function modules are architecturally supported. Thus, by design, there is no semantic gap between the specification, programming and machine execution levels enabling the safety licensing of application software by diverse back translation, an extremely simple but rigorous method.
