Basic PLC Instructions (Full Lecture)

In this lesson we'll define the make, break, and output enable instructions common to most PLCs as well as differentiate between electrical continuity as required by traditional hardwired relay based ladder logic and logical continuity as required by most PLCs. Pay attention to this lecture as it establishes fundamental ground rules about common PLC program instructions that, if misinterpreted, can be disastrous. (Full Lecture)

The 8 states considered from 21:10 are very simple if you put it in a written table and mark the columns according to their "Normal" "Deactivated" or "Activated" states.  What must upset first timer electricians is that they probably don't get taught or don't have an inclination to learn about simple digital electronic switching. One would think it should be a compulsory part of an electrician's study syllabus.

[Sundasher]

Hallelujah!! I knew he was out there somewhere, the guy who can ACTUALLY explain this in a logical and concise manner... you are THAT guy. No unnecessary rambling!! Thank you!!!

[wonders]

Jim, your presentation of basic PLC programming is so crisp and articulate, right to the point. Simply genius! God Bless you!

[PattiHoff-biwx]

I'm an electrician just jumping into the automation/controls side of things and here teaching myself how to program when work is slow. Thank you so much for providing such well explained classes on YT for free. Definitely have to mentally separate NC/NO and XIO/XIC! (which reminds me of my instructor as an apprentice making us state "The common is not the neutral." over and over again.)

[troubleshooting]

I started out as an electrician in a factory and converted old manual operated hydraulic and pneumatic machines into plc electrical operated automatic ones! I was 17 at the time!! 😲

[bladedance]

Really Helped watching a second time for those who are lost you are not alone. My tip is watch other videos after this then come back and watch for a second time!

[Michael-jpjw]

Holy smokes! This has got to be THE BEST lecture introducing PLCs. Definitely will "put it in my pipe and smoke it!"

[jesseamaya]

I'm an industrial compressor technician and I routinely have to wire and rewire control boards. I did not know I was using ladder logic until I watched your video (several times). I just purchased a plc and several modules with the intent of training myself on how to program them. Your video is clear and concise with clear and easily understood illustrations. Thank you.

[airman]

I taught at a community college....primarily hydraulics and pneumatics. I'm now retired and I still check out your videos. Thanks for being such a dedicated instructor. I really appreciate it! Simply great, no doubt!

[pabloetchepare]

I'm so happy for the first time in my life to start learning about PLC's . Thanks :)

[keithclark]

I just started learning PLC and only have view a few videos. This video is great! I love the way how important it is to Jim. Someone like this are the ones you want to learn from. Detail, detail, detail...you have to be detail to be good.

Mr. Patel: THanks a million, brother.

[jaltoorey]

ur great. i came for EXACTLY this video with ALL of the tone and ALL of the sentiments and the driving it in my head. I can't learn this the other way teachers would try to teach. You are talent. Thank you dearly and kindly.

[markangelocaban]

Thank you for this video i have refresh my plc programming subject way back 2008..

[jacquesbouchard]

Thank You so much!!! I struggled a freaking lot with this mechanical vs logical concept, you made it much clearer now ! I should have found your channel sooner!

[adwayduttagupta]

Awesomely explained. 30 minutes of my life was worth it.

[TheElectromagno]

I have never seen a good explanation about Plc like this lesson did. Thank you very much.

[quynhnd]

Thanks you so much.
I didn't understand this problem before; thanks to you, i understood this problem.

[GovernmentAcid]

MAN, thank you for making this so clear & understandable. I'm currently in an AAS program for Electrical Engineering Technology (currently making A's in all of my classes, largely because of the solid foundation in circuit analysis that this channel gave me), and I take PLC's next semester, before graduating Spring of 2023. I think I was always a bit intimidated about taking PLC's, because I always knew that it was one of the final classes I would take, and I think I was just afraid somehow that there would be a sudden difficulty spike from one section to the next, and largely thanks to the foundation that I found on this channel, I don't think that'll be the case. I'm also lucky to be in a program that makes construction of logic-based circuits really intuitive as well, and I've been able to get a lot of lab practice with those using just simple breadboard kits and various IC's and other electronics components. Anyways, thanks again, and this content is really stellar for someone who's just learning & wants to get a solid foundation.

this presentation is a testament as to why unified standard system should be used with these things, instead of each branch using their own symbology
the -] [- and -]/[- in particular, when the thing could have been written as -] [- and -] [o-, which would instantly make much more sense for anyone being remotely familiar with symbols for logics in electronics
