Structured texts serve several important purposes: 1. Programmable Logic Controllers (PLCs): Structured Text (ST) is used in PLC programming to handle complex control logic, making it accessible to developers familiar with high-level programming languages like Python, Pascal, and Java. 2. Data Interchange and Standardization: Structured text formats, such as XML, JSON, and YAML, facilitate data exchange between different systems and ensure data integrity when transferring information across networks or software applications. 3. Improved Readability and Maintainability: By enforcing a consistent structure, structured texts make code and data easier to understand, manage, and update, reducing the likelihood of errors and inconsistencies. 4. SEO and Content Management: Structured content helps search engines crawl, categorize, and rank content, improving its visibility and click-through rates.
