Excellent explanation. I like the ways you explain as a person who has tons of engineering experience. Thank you.

Awesome video - very concise and thorough walkthrough of the different timers, a couple of which I've never wanted to mess with because I didn't understand well enough. Thanks for all the quality content you put out!

I'm not sure if this is the scope of the question or not but I wanted to take a crack at it. In the processor the CPU has a digital clock everything in the PLC is timed on this clock. One good thing to look at to get an understanding of how this works is to look up timing diagrams and digital logic. I'm not sure if this is what you meant here or not, but just thought I would take a try. By the way great video, as always. I find myself watching your videos more often than not on my way to work, because you have a way of explaining things to where I always gain some sort of insight even from the basics. Are there something I haven't thought about or something that I can't gain from the textbook. I hope people see the value that you are really adding to their life with the content that you create, it really will change someone's life. Thanks as always Tim

Thank you so much. Keep uploading informative videos. You're a big help.

Great video, I didn't know about timer TT bit. You didn't explicitly mention how to handle an input that only goes true once (a momentary push button), to start the timer, and doesn't stay on. It wasn't immediately obvious to me that I had to add a branch below the momentary input to XIC the timer TT, which will only stop the timer when it's done counting.

I have always wondered why they hide the TT bit. Thanks!

What a grat explanation! Thank you very much! That's the way to explain things. Keep it up!

In the event of a black out or brown out condition will this program force an operator to press a reset button to continue, thus providing low voltage protection?

Hi Tim

I work as an electrician at a slab factory in Scotland and I am trying to add an external timer for our hydraulic press so the operator can adjust the press time without me having to go in through the plc. Do you have a video that would help with this? Or could you point me in the right direction?

Many thanks

Hi tim greetings

Can timers count floating numbers?

I mean, in the Preset of the timer, for example, place a value of 2.4s.

 it's possible??.

Thank you so much sir for nice explanation

Great videos Tim and Amber! I am having some trouble. I'm trying to get back into programming after about 25 years of not doing it and your videos have been very helpful. I'm able to communicate with the MicroLogix 1200, but when I try to download a different program to the PLC it gives me fault ( no response from processor at selected path/ node! Diagnostic Status failed: 0x4 ). Can you tell me what I'm doing wrong?

Dear Sir, thank you for your great videos. In this lesson you say that we can use timers to count for example how many times the Motor runs ON, but as you know we can only count as Max. for 9 hours, so how can we count the Motor run time if this Motor runs for Weeks or Months or longer than that ?

Where I can get video where you get TOM connect in parallel reply name of video or link plz

Can PLC control the application installed under Windows?

It's a bit hard to understand having only a computer simulator to run rpograms, nevertheless very interesting, thanx!

[jordanlong]

how did you stop it on exactly 800 haha.
