    Hi,
    what device are you using? There could be manufacturer's libs that do it.

    As general advice I will use the classical way of embedded system: create a variable and count cycles (assuming that your process is in ciclic task).

    Another way could be to use the Task configuration > Monitor tab.

    Hi Francesco,

    Thank you for your reply,

    I used SysTimeRTC library to get the PLC time.
    I wrote a if function a boolean variable true then freeze the start time in a date_time variable.

    Warmest regards,
