PLC Controls with Structured Text (ST): IEC 61131-3 and best practice ST programming

Description

IEC 61131-3 and best practice ST programming This book gives an introduction to Structured Text (ST), used in Programmable Logic Control (PLC). Further the book can be used for programming in Siemens Structured Control Language (SCL) and for Programming Automation Controls (PAC) CONTENTS - Background, advantage and challenge when ST programming - Syntax and fundamental ST programming - Widespread guide to reasonable naming of variables - CTU, TOF, TON, CASE, STRUCT, ENUM, ARRAY, STRING - Guide to split-up into program modules and functions - More than 90 PLC code examples in black/white - FIFO, RND, 3D ARRAY and digital filter - Examples: From LADDER to ST programming - Guide to solve programming exercises Many clarifying explanations to the PLC code and focus on the fact that the reader should learn how to write a stable, robust, readable, structured and clear code are also included in the book. Furthermore, the focus is that the reader will be able to write a PLC code, which does not require a specific PLC type and PLC code, which can be reused. The basis of the book is a material which is currently compiled with feedback from lecturers and students attending the AP Education in Automation Engineering at the local Dania Academy, "Erhvervsakademi Dania," Randers, Denmark. The material is thus currently updated so that it answers all the questions which the students typically ask through-out the period of studying. The author is Bachelor of Science in Electrical Engineering (B.Sc.E.E.) and has 25 years of experience within specification, development, programming and supplying complex control solutions and supervision systems. The author is Assistant Professor and teaching PLC control systems at higher educations. LinkedIn: https: //linkedin.com/in/tommejerantonsen/ Review: Into to Structured Text - PLC Primer - Reference - This is a good book and an excellent first step in Structured Text. (ST) I can say very many good things about the book and I do wish there was more but I will not focus much on the negatives as respectfully the subject is new to me and also I respect the author has crafted a fine, very direct piece that is intended to educate within a scope and NO, not everything is possible in 124 pages!! I work on Beckhoff and took their class and realized I didn't know enough ST to properly read code and troubleshoot...I bought this book DURING the class. Again I give my opinion here but kindly and respectfully to the author as the book fulfilled its objective and most of what I would say would improve but again is NOT criticism. The reading can be dry...at first I thought author style and perhaps Danish...so if English is not first language may sound different to us. However, realize the book written in Danish and translated...so that has added to the problem. The long experience of author could be better used with slightly more background on expressions, datatypes, variables, and showing those more simply and including assignment operators...it was page 71 before I knew => was OUTPUT. Some color and side tips and diagrams would make it more pleasant and easier to read...your brain fights to digest code examples when not used to PLC code or ST then too much rereading and question marks. BUT, this is 124 pages, black and white, with good examples and you learn what you came for. Could be better organized, stylish with color and clearer, better examples but I learned from it and I would recommend it for anyone wanting to understand ST using any PLC. Review: Basic Syntax Reference Only - Reasonable reference to ST programming language syntax. Does not provide much information about how to properly structure a PLC program using the ST language. Does talk about good programming practices in general but not very in depth.
