In this video, you will learn how to create a function block for a retentive on-delay timer. Retentive timers keep their elapsed time and do not start from zero once their input gets off and on. CODESYS does not have Retentive on-delay timers and in case you need one, you should create your own.
It is quite important to pay attention to the order in which the program rungs/branches appear. You can try to exchange their position and see that the timer will not work as you expect.
