Can you please give some real world examples of when it makes sense to incorporate periodic tasks that don't need to be continuously scanned? Great video!
So much details here, had to stop and rewind many times. I'm also going to agree with a commenter below in you giving a or several examples of a process or more that may not need to be scanned on every scan of the processor. Assuming you were running a industrial water purification system at a plant site with chemical feed systems, what would you put on periodic task that don't need to be on continuous? I can say having seen many logic ACD file for many of our OEM company various projects, there aren't usually any periodic tasks. There is very much just one continuous Task, Mainroutine and many other rungs in that routine with a JSR in the main rung. I've seen as much as 25+ rungs under that one Mainroutine each separated for processes. Analog I/O mapping, Digital I/O mapping, Equipment Logic routine, Permissive etc. Never usually periodic tasks i've seen. I'm just a junior programmer so i'm not sure what the answer is for that in our logic programming. So an example or few would be great. However, i'm going to take a guess in that Events could be Safety Process Shutdown logic routines where things need to stop fast and quick in the event of safety issue.
Hi Guru nice video, I have one question, the order of execution of the periodic tasks (who executes first and who then) goes from top to bottom? Or dependding of the time scan and the prioriti? Thanks!
Hi Manuel, thanks for your comment. You have the ability to set the priority of the tasks by right-clicking the task --> Properties -->Configuration. From here you can set the priority of the task (the lower number yields a higher priority therefore it will execute first). Hope that helps.
One doubt I got is if the program cyclic scann happens in the period indicated o set, I mean if we indicated 10 ms, it means that if it would happens in 10 ms even if the program to scann is too big? Or it takes weteaver it would be, and wait 10 ms and then start again

Nice example to make people easy understanding!!! Great job!

I'd like to see this example as well. Great videos

Very good. Now I can make blinking without timer.😀😀
Thanks for good explanation.
GREAT 👏👏👏
THANK YOU VERY MUCH SIRJI🙏
Very good
