What is Structured Text?

Structured Text (ST) is a high-level programming language commonly used in industrial control systems and programmable logic controllers (PLCs). It provides a structured approach to writing code, allowing for efficient development and maintenance of complex control algorithms. ST follows a block-structured syntax, similar to Pascal or C languages, making it highly readable and easy to understand.

To illustrate the practical application of Structured Text, let’s consider an example scenario: controlling the temperature of an industrial oven. Using ST, a programmer can develop a set of instructions that monitor the temperature sensor data, adjust heating elements based on predefined criteria, and log any deviations or errors encountered during operation. This helps ensure precise control over the manufacturing process while maintaining safety standards.

Implementing Structured Text offers several advantages in industrial controls:

  • Increased efficiency: The modular structure of ST allows for reusable code blocks, reducing duplication of effort and minimizing potential errors. Developers can create libraries containing frequently used functions or routines that streamline future projects.
  • Enhanced readability: With its clear structure and limited use of special characters, ST improves code readability compared to other programming languages commonly used in industrial automation. This facilitates easier debugging and maintenance by both original programmers and subsequent users.
  • Flexibility: Programmers have the freedom to mix different programming paradigms within their ST code, such as procedural or object-oriented approaches. This flexibility enables customization according to specific requirements without sacrificing performance or stability.
  • Interoperability: PLCs from various manufacturers support Structured Text as part of their standard programming languages. This ensures compatibility with different hardware platforms and simplifies integration into existing control systems.
