Hi everyone,

In CoDeSys, as it's based on the IEC 61131-3 standard, it supports a variety of data types specified by this standard. Here are some data types used in CoDeSys and how they are used:

    Elementary Data Types: These are the simplest data types and directly represent basic values or states. Among these types are:
- BOOL: A boolean data type representing a true (TRUE) or false (FALSE) state.
- BYTE, WORD, DWORD, LWORD: Respectively 8, 16, 32, and 64-bit integers.
- SINT, INT, DINT, LINT: For signed integers, respectively 8, 16, 32, and 64-bit integers.
- USINT, UINT, UDINT, ULINT: For unsigned integers, respectively 8, 16, 32, and 64-bit integers.
- REAL, LREAL: Represent floating point numbers, REAL offers 32-bit and LREAL offers 64-bit resolution.
- STRING, WSTRING: Represent strings and wide strings.

    Derived Data Types: These are more complex data types that are based on the elementary data types or use other derived data types. Among these types are:
- Array: Represents a sequence of items of the same data type.
- Struct: Can contain items of different data types, each item is given a name and accessed by that name.
- Union: Similar to structures, but all items in a union share the same memory space.
- Enum: Represents a predefined set of values.

    Complex Data Types: These are user-defined custom data types and usually represent the properties of a specific function block or an object.

Each of these data types in CoDeSys allows you to store and process data of specific types in your code. The data type used can significantly impact the functionality and efficiency of your code, so it's important to make a careful decision about which data type to use.
