High-level, textual programming ideal for complex mathematics and data manipulation.
If you are opening the CODESYS 3.5 manual for the first time, prioritize mastering these foundational concepts. The Device Tree vs. POU View
: Managing user permissions, project encryption, and secure communication.
Efficient programming relies on reusable code. The manual details how to use standard libraries (like SysTime or Util ) and how to create your own custom libraries. It also defines standard data types (INT, REAL, STRING, TIME) and user-defined data types like structures (STRUCT) and enumerations (ENUM).
