Common trends in the development of component base of the present automation

Abstract

The paper is concerned with the research of the possibilities for applying programmed logical controllers (known as industrial controllers) in safety-critical systems. A two channel structure, "2-out-of 2", is offered due to which a concrete solution is presented that shows the application of industrial controllers for realization of technical appliances with "fail-safe" behavior. By analysing the offered structure, we aim to present indicators of reliability and safety. Research has been done of the indicators that have been drawn to our attention, and the results are discussed.
