<div class="markdown_content"><p>Hi,</p> <p>in CoDeSys there is a very simple method to measure execution durations. </p> <p>FUNCTION TIME() returns the CPU time stamp. You can store it in a variable of TIME type, or as a DINT (TIME_TO_DINT converts to milliseconds). Later, after a second TIME() call, you can subtract the previous CPU time stamp.</p> <p>This way you could find the execution duration of your program. Then set task cycle to an appropriate value.</p> <p>Regards</p></div>
