Hi everyone,

CoDeSys is an automation software designed according to the IEC 61131-3 standard, and as such, it includes a wide set of commands defined by this standard. CoDeSys supports five different programming languages: Ladder Diagram (LD), Function Block Diagram (FBD), Structured Text (ST), Instruction List (IL), and Sequential Function Chart (SFC).

Each language has its own specific set of commands, but generally, the commands in CoDeSys can include:

    Arithmetic Commands: These commands are used to perform arithmetic operations such as addition (+), subtraction (-), multiplication (*), division (/), and modulus (%).

    Logical Commands: These commands are used to perform logical operations such as AND, OR, XOR, and NOT.

    Comparison Commands: These commands are used to perform comparison operations such as equals (==), not equals (!=), greater than (>), less than (<), greater than or equal to (>=), and less than or equal to (<=).

    Control Commands: These commands are used to perform control structures such as IF, ELSE, CASE, WHILE, REPEAT, and FOR.

    Block and Function Calls: These commands are used to call predefined or user-defined functions and function blocks.

    Variable Assignment Commands: These commands are used to assign values to variables.

    Time Functions: These commands are used to wait for a specific amount of time or execute an operation over a specific time interval.

This is just a start, and there is more functionality and more complex commands available. For more information on the CoDeSys command set and language features, refer to the CoDeSys documentation and manuals.
