PLC Programming In Instruction List According To IEC 61131-3, 5th EditionНазвание: PLC Programming In Instruction List According To IEC 61131-3: A Systematic And Action-Oriented Introduction In Structured Programming, 5th Edition
Автор: Hans-Joachim Adam, Mathias Adam
Издательство: Springer
Год: 2022
Страниц: 245
Язык: английский
Формат: pdf (true), epub
Размер: 24.5 MB

The book is written as a textbook and exercise book. This means that you will be introduced to new areas through explanation or examples. To consolidate your knowledge and to check your learning and success, we recommend that you do the exercises. Sample solutions are available for most exercises: Each exercise has a unique name under which the solution can be found on the authors’ website. An integral part of this book is the PLC simulation software “PLC-lite”, which was developed by the authors especially for this course. You can download it free of charge from the authors’ website. This gives you the opportunity to intensively test a control system that conforms to the standards, regardless of limitations with real systems. The scope of commands, data types, structures, etc. has been selected in such a way that the special features of programming in instruction lists according to IEC 61131-3 can be easily understood using the exercises from this book. In addition, “PLC-lite” contains a large number of processes as animated simulations. This allows you to test your programs in a practical and safe manner and to study the behavior of the controlled processes (even under extreme conditions or “errors”). Your PC is thus both a programming device and PLC automation device as well as a “technical system”.

Coherent Optical Wireless Communication Principle and ApplicationНазвание: Coherent Optical Wireless Communication Principle and Application
Автор: Xizheng Ke, Jiali Wu
Издательство: Springer/Science Press
Год: 2022
Страниц: 474
Язык: английский
Формат: pdf (true)
Размер: 17.6 MB

This book presents the key technologies of coherent optical wireless communication, covers topics such as beam coupling, signal optical polarization control and distorted wavefront correction. It discusses the principle of coherent optical communication and heterodyne detection conditions. In this book, the array coupling receiving technology and large aperture coupling technology are introduced to realize the spatial optical fiber coupling; simulated annealing algorithm, particle swarm optimization algorithm and SPO algorithm are used to control the polarization state of the signal beam; and the correction of distorted wavefront of the signal beam by adaptive optics technology and wavefront sensorless adaptive optics technology are analyzed, and the influence of beam mode on coherent detection performance is elaborated. Both theoretical deduction and experimental results are included in this book, which can help readers further understand the theoretical knowledge.
