Hi everyone,

In CoDeSys, timing and scheduling can be accomplished in several ways, including through the use of time-delay functions, task configuration, and timers.

    Time-Delay Functions: CoDeSys supports several built-in delay functions, such as SLEEP, DELAY, and WAIT in the Structured Text (ST) programming language. These functions can be used to introduce a delay into the execution of your program.

    Task Configuration: In CoDeSys, tasks are used to organize and schedule program execution. Each task can contain one or more programs or function blocks, and each task can be assigned a priority and a specific execution interval or event.

    Timers: IEC 61131-3 includes several timer function blocks, such as TON (Timer ON Delay), TOF (Timer OFF Delay), and TP (Pulse Timer). These timers are used to delay the execution of parts of a program or to create repeating operations.

    For example, the TON timer starts timing when its input condition becomes true, and it sets its output to true after the specified time delay. The TOF timer, on the other hand, starts timing when its input condition becomes false, and it sets its output to true for the specified time delay.

Remember that the timing and scheduling mechanisms you use depend on the specifics of your application and the programming language you are using. Always refer to the CoDeSys documentation and your hardware's specifications for the best practices and limitations for your specific situation.
