Programmable Logic Controllers: Architecture and Applications

The aim of this study is to set out all the information necessary and sufficient for the understanding of the PLC considered as machine, as system and as tool. It is also intended to set the PLC in the context of existing technology: wired logic technology and information processing technology. This is an introductory text in which particular attention has been paid to normative concepts, by putting forward several definitions in the vocabulary of logic controllers, and to methodologies of project management, in which competence and experience will lead as directly as possible to practical working systems.
