This training manual is a structured collection of 100 practical programming examples for industrial controllers (PLCs) using Structured Text (ST) in accordance with the IEC 61131-3 standard.
The material follows a "from simple to complex" approach, covering all key automation tasks: from basic logic and timers to advanced algorithms for pumping stations, conveyor systems, and integrated production lines.
Key features:
Fully functional code with variable declarations and comments in Russian.
10 thematic sections covering a complete range of industrial applications.
Adapted for CoDeSys and TwinCAT development environments.
Verified for compliance with the IEC 61131-3 syntax.
Perfect for self-study, course projects, and practical work in industrial automation.
