Beskrivelse

Discover the basics of Ladder Diagram (LD) programming for Programmable Logic Controllers (PLC) with this beginner-friendly guide. It's designed to help those without an electrical background get started with PLC controls.

An accessible introduction to Ladder Diagram programming for PLC systems.

This book offers a comprehensive overview of PLC controls using Ladder Diagram, applicable across various PLC brands. It’s tailored especially for readers new to Ladder programming, making it ideal for learners without prior experience in this field.

Filled with clear illustrations and practical program examples, the content is based on real-world automation challenges. You'll find detailed coverage of:

• The background, advantages, and challenges of Ladder programming
• PLC hardware basics, sensors, and introductory Ladder programming
• Practical tips for creating well-structured programs
• Theory and examples involving flowcharts, block diagrams, and sequence diagrams
• Guidance on designing functions and function blocks
• Methods for organizing code into program modules and functions
• Sequencing techniques using SELF-HOLD, SET/RESET, and MOVE/COMPARE
• Complex programming examples for systems like pump stations, tank controls, and conveyor belts
• Steps for designing, developing, testing, and simulating PLC programs

The book follows the IEC 61131-3 standard for Ladder programming, but it also notes that different PLC vendors may interpret this standard differently. As a result, some examples may not function exactly as shown on every PLC type, and graphical symbols or instructions might vary.

Keep in mind, this is a beginner’s guide and does not cover advanced topics such as ARRAY, LOOPS, STRUCT, ENUM, STRING, PID, or FIFO.

Written by Tom Mejer Antonsen, an author with multiple publications and over 15,000 copies sold, this book is a reliable starting point for anyone eager to learn Ladder programming.
