Professional PLC Programming Guide for Structured Text (ST)
This comprehensive technical manual provides practical instruction in Structured Text (ST) programming for Programmable Logic Controllers (PLC). Compatible with all major PLC brands including Siemens Structured Control Language (SCL) and Programmable Automation Controllers (PAC), this guide follows IEC 61131-3 standards.
What You'll Learn
The book covers fundamental ST programming syntax through advanced applications, with more than 90 PLC code examples demonstrating real-world implementations. Topics include CTU, TOF, TON, CASE statements, STRUCT, ENUM, ARRAY, and STRING operations. Advanced sections cover FIFO buffers, random number generation (RND), 3D arrays, and digital filtering techniques.
Practical Programming Approach
Learn to write stable, robust, and reusable PLC code that works across different PLC types. The guide includes detailed instruction on variable naming conventions, program module organization, and function development. Practical examples demonstrate conversion from LADDER logic to ST programming, making it accessible for programmers transitioning between languages.
Structured Learning Path
Each chapter provides clear explanations of PLC code with programming exercises designed to build practical skills. The material addresses common challenges in ST programming and provides solutions based on industrial best practices. Focus on creating readable, structured code that can be maintained and adapted for different control applications.
Industry-Tested Content
Developed and refined through feedback from automation engineering students and lecturers at Erhvervsakademi Dania, Denmark. The content addresses typical questions and challenges encountered during PLC programming education and professional practice.
Author Credentials
Written by Tom Mejer Antonsen, Bachelor of Science in Electrical Engineering (B.Sc.E.E.) with 25 years of experience in control solutions and supervision systems. His background includes 7 years of Pascal programming and 12 years developing PLC-based systems. Currently serves as Assistant Professor teaching PLC control systems at Erhvervsakademi Dania, Randers, Denmark.
This technical manual serves as both a learning resource for students entering automation engineering and a reference guide for professionals working with PLC control systems. The emphasis on vendor-independent, reusable code makes it applicable across various industrial automation environments.
