I’m an electrician who joined a company who does a lot of industrial work bringing power to tons of motors, switch gears, smart panels and a lot of controls going back to multiple PLC cabinets. We have one guy who does the programming and another who does controls. We have tons of electricians none of which understand controls. You just brought me into the game. Being the first to understand both worlds in this company. I Might not be a professional in controls but I sure understand it now. Thank you my friend
This professor has done a great service to learner's. Although I am a programmer, I could never have given such clear explanation. Thank you Sir, Keep up the good work.
You can't ask for a better video tutorial. I understood everything you explained. i had to go back a few times, but I eventually got it. The pictures and the way everything was set up was perfect. Great video.
I am about halfway through this video, after having watched part 1. I have basically no PLC background, an amateur electrical background, and lots of programming background. I actually understand now how an input module isolates field wiring from PLC wiring. It became an epiphany as to how the whole process automation scheme works on a grand scale. When the normally open contact to the light bulb above my head became True, I was going "Wow. Wow!" My wife quirked an eyebrow at me. I said, "Honey, you don't understand. This transcends any religious experience!" Hyperbole, of course, and some of you more advanced people may sneer, but I am ever grateful to the folks at plcprofessor for having the heart to produce this video and the balls to make it freely available.
Excellent. This refresher has been exactly what I needed in a short but detailed package. You may count yourself amongst the "good guys" for doing this!
At my 57 years I went again to school to get my electrician carta proffesional II, I have a solar energy company and with your help I will pass the test next week. It is so nice explained, thank you Sir. Greetings from portugal
Thank you for the excellent teaching. This was very clear thanks to your 'foundations first' approach. The progression from relay basics to the more advanced PLC hardware really made this very understandable. You are a gifted teacher.
Taking PLC fundamentals at college, his video has thought me more than what I've learned in the entire semester !! Way to go professor, now I need to learn how to program
Thank you so much.. I am beginning a job in controls and have absolutely no experience. These videos have enabled me to learn the PLC fundamentals without going to school and better yet for free! Your dedication to online learning is much appreciated :) !!! Thank you
This video is top notch for training and educating. Thank you very much for taking the time to put these together. Thanks for sharing and doing such a great job of narrating and educating our technicians!
ok professor, i watched this video, and its starting to make sense now about the true if on, false if off, or true if off, false if on, your great, not knocking my instructor, but i can really understand you alot better than i can him, man your a godsend to me, and i may just have a chance at passing this class
plcprof, Again, this is a great video. I am reviewing these, but learning a lot in the process. I like what you have done and have encouraged others in my group to watch these also. Keep it going.
i vaiue all the information that your teaching me. Ive shared you site with my friends and hope they support you. With what your teaching me im sure i get a better job and my mind is always learning something new keep up the good work and God Bless You
Really helps those of us with a pre-existing knowledge of electricity and schematics. A great started video. I'd like to see more of his explanation videos of more in depth programming.
Jarn Hazir 🤣🤣🤣My computer science friends and I used to call it the "Jaba acshent" because every Java(the programming language) video tutorial I looked up was in an Indian accent, didn't know engineers had the same experience too😆. But Indians are the best, they are very knowledgeable, hardworking and keen on selflesly sharing their knowledge with the world 😊, I feel like you tube needs to have an Indians appreciation day on RUclips 💁♀️💁♀️💁♀️ (My main issue with indian videos wasn't so much the accent as it was the general expressionlessness both in voice tone and in facial expression, not sure if its a cultural thing, but with my attwntion span, the monotony was a huge barrier to learning) As well as a PLC Professor appreciation day, HE'S SIMPLY AMAZING.
No offense but I can't stand to Indian accent and engineering videos are all like that so I try to listen to them for and can't even stay for a minute listening.
I had a recruiter calling me the other day, had to turn down the interview opportunity because I couldn't understand the job description. no offense but damn
Just want to say thanks so much Professor for the teachings! Im in the process of wanting to advance in my job and electrical has always been my weekest point. Very well explained and I learned alot! Thanks Again, Kevin
thanks so much for putting the time and effort into something so powerful and beneficial such as plc progamming.I'm in the process of taking my PLC classes and th ese videos really helped me a lot. thanks professor and keep up the good work. you ROCKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKK.
I am currently in my 3rd week of plc class at the local community college pursuing a AAS degree in electronic and controls. I have been working in the automotive industry for 5 years as a setter/maintenance, and i have a good understanding of that side of things. After watching your first video and part way into the second, it is just all coming together at a rapid pace. Thank you! I just wonder why the instructor at the college does not take a similar approach, he seems to be all over the place.
I have been blessed with exposure to industrial automation in more ways than most, blessed with the opportunity to work on processes from every sector of industry, many years as a technician, then as an engineer and teacher. The Lord blessed me with a strong desire to teach what I learn and I learn everything in a way that I can explain it. Regardless, most things come with age and experience. Most of what I learned was not in a classroom.
Abdul Rahman Naik There is no other Living God but that of Abraham, Issac and Jacob and there is no other way to a right standing with the living God but through the perfect work of His Son Jesus the Christ. That perfect work of Jesus cannot be earned, it can only be accepted as a free gift of His Grace and Love to all of mankind.
Subhana Allah ...(All glory belongs to Allah) if one can wrap his head around the logic of PLCs, then one has the Logic open himself to Islam... If Allah favors one with guidance. AbduR-Rahman as far as PLCs go you have more of a advantage then most of us, after all Allah did your kin folk to bring us the "0" lol and the walking computer himself ... Dr. Naik may Allah bless him. Ameen !!! Dr. Naik calls us to worship the Creator instead of the created. Just the way Jesus, Muhammad, Abraham, Issac, Jacob and our father Adam (peace on them all) did. here we go, peace
This is excellent - thank you so much for your insight and step by step explanation. This has opened up my understanding as a Mechanical Engineer to PLC's. I sincerely appreciate your time and energy to help us understand. Kind regards, David
Thank you so much Prof. This is great now I have a clearer view of what a PLC is because currently I am only working on hardware of relays, contactors, solenoid valve and etc.. This will really help me a lot in stepping up to a new level and it's something to do with this feature of Programmable Logic Controller.
What is the class you are taking, if I might ask? After years of both controls engineering and teaching, I still learn something new every time I teach a class. Never stop learning, never stop visualizing your challenges. If you really want to understand something, try explaining it to someone else. You will be amazed at what comes to you when you are searching for the right word picture to illustrate a point.
I think its a great tutorial, I'm not sure if anyone caught that but I think that Hex : A0F1 is equal to Dec: 41201 because in binary it's 1010 0000 1111 0001. I'm a n00b so If I'm wrong please comment. Thanks so much professor and the entire audiences!
Lost me at 1:23 I'm old school too much terminology seems like you go to logic control plc writing everything is backwards you're making electrician be an instrumentation person and then you're making them an engineer then you're making a software Hardware developer that's a problem going to a job interview many companies want you to know the ladder programming I'm electrician I give you power you do whatever you want to do with it companies don't seem to understand that greatly don't want to pay you for it but you've taught me a lot so far my memory is mush I think this is what happened when you get three kinds of people trying to engineer design program in install one machine on paper you're very good teacher and thank you I watch your videos Another Day
Yes, you are correct. Unfortunately I normally mention to my classes that this is a representation and not a warranty of actual electronics. In reality there would be a myriad of components between the I/O wiring arm screw terminal and the memory bus. I just thought of a solution, I will make a note to myself to add a note on that section to mention the same. Thanks for the feedback, it all helps. Again, thanks...
It is correct, and I go on to explain why people confuse the input device state with the symbols in relay ladder logic. DO NOT THINK relay contacts when you are analyzing RLL. The NO symbol is true if the bit in memory is ON, the NC symbol is true if the bit in memory is OFF, True if On and True if Off are the symbols in RLL, not Normally Open and Normally Closed.

The pleasure is mine...Thank you for the vote of confidence :)
This is great professor explained in detail with plc. Programming THANK YOU FOR explanations.
PLC Professor, these videos are beyond fantastic. You have truly made a positive contribution to the world. Thank you.
You can't ask for a better video tutorial. I understood everything you explained. i had to go back a few times, but I eventually got it. The pictures and the way everything was set up was perfect. Great video.
The pleasure is mine...thank you.
Just watching these lectures now as I'm studying a degree in mechatronics and they're fantastic! Thank you so much for these

all lies electricity - plc is a system in switching mode by the transmission of light...
you said thank you for watching but we say thank you for teaching to understand basic information
Excellent. This refresher has been exactly what I needed in a short but detailed package. You may count yourself amongst the "good guys" for doing this!

The pleasure is mine...el gusto es mio.
Masterful teaching. Thank you for explaining the Fundamentals first.
God bless you for making this public and free of charge.
Thank you for the excellent teaching. This was very clear thanks to your 'foundations first' approach. The progression from relay basics to the more advanced PLC hardware really made this very understandable. You are a gifted teacher.
Thank you very much.. This is by far the best lesson on PLCs that I have found on Internet. Highly recommended!
thank you...
I've never had a thorough lecture like this....really downtown basics! Thanks so much prof!

Glad it was helpful!
Thank you for taking the time. I am beginning to understand. Your patience and persistence is making a difference.
Thank you, what your doing is truly helpful to mankind. The abundance of knowledge is changing my life.

amazing tutorial . I watched both the parts in one go. Simple and clear.
Awesome, thank you!
The most complete and detailed material that I´ve seen available to learners. Congratulations and thank you soo much professor.
I just wanted to say that I greatly appreciate all the work you have put into this 2 part introduction.
Sir, It's strange without introducing yourself in photo or picture you explain the PLC course in simple way, It's great.Thnx
plcprof, Again, this is a great video. I am reviewing these, but learning a lot in the process. I like what you have done and have encouraged others in my group to watch these also. Keep it going.
Plc Professor, you are the best. You make an interesting subject even more interesting. Thanks
The pleasure is mine...

Thanks for spend your time teaching other ones these two videos are really good, I´ve learned a lot.
Professor thanks very much for your efforts the detail and effort you go into for people with no experience is as good as it gets. Very grateful :)
Really helps those of us with a pre-existing knowledge of electricity and schematics. A great started video. I'd like to see more of his explanation videos of more in depth programming.
This is the first video I've seen on engineering by someone that doesn't have an Indian accent

Thank you very much i really enjoyed the ride and i dont recall the last time i learned that much from a youtube lecture.
You're very welcome!
Thanks for sharing very good presentation it's helpful
Very good explanation and demonstration.!! It is much more clear to me how the PLC logic works. Thank you
Great work. Excellent video for the PLC learners. Thanks a lot.

Thanks for the upload! :)
This is excellent - thank you so much for your insight and step by step explanation. This has opened up my understanding as a Mechanical Engineer to PLC's. I sincerely appreciate your time and energy to help us understand. Kind regards, David
This is great. I had a couple teachers like this in school. Very good, knew how to explain things to make people understand.
Another great PLC video...keep up the great teaching
Your explanation is great and easy to understand. Thank you sir.
Thank you so much Sir, for sharing this video with us. This is a big help for me as an industrial electrician.
thank you "plc professor" for the tutorial simple and effective.
Thank you, I am reentering the job market and this was great refresher. Good job.
Dear professor, thank you for giving us such a good training.
It's my pleasure
I appreciate, sir. always feel comfortable with your lectures. thank you very much❤
Your lectures are fantastic
came from military and just doing relays this has been helpful as a transition to civilian world with plcs
thank you...
Very good, sir. You are an excellent instructor, thank you.
The pleasure is mine...
Excellent video, thank you very much for your time dedicated to the development of video, Greetings from Mexico!!!
el gusto es mio...
This was an awesome presentation. Parts 1 & 2. Thank You!!!
PlcProfessor thank you very much for the free knowledge!!!
You are awesome!!!
Thanks you so much sir, for your video it so clear and educative keep it up, yearning to know more from you as programmer beginner.
Thank u so much I feel so confident now to approach PLCs without that fear ;)
This is absolutely excellent. Keep it up professor
Thank you sir. This was very confusing for me but you explained it in a very smooth way!! Thanks again.
Thank you for taking time to straighten out the tricky stuff right around1:00:00. Very helpful!
Thank you so much Prof. This is great now I have a clearer view of what a PLC is because currently I am only working on hardware of relays, contactors, solenoid valve and etc.. This will really help me a lot in stepping up to a new level and it's something to do with this feature of Programmable Logic Controller.
great video thanks so much, am learning so much continue to take your time for us, slow learners
thanks for an awesome explanation great job, greetings from a mexican !!!!
Thanks for the beautiful explanation. Great job..
Thank you for this information this was very helpful to me.
You are so welcome!
ABSOLUTELY THE BEST!! You have a teaching gift, sir.. THANK'S!!
Thank you for such a clear and concise explanation!!!
Pretty specific and with nice examples! I like it!
at 22.00 the hexadecimal number A0F1 should be 41201 in decimal. Great job on the videos.
Thank you so much for the videos. I watch tubalcain videos for my machine shop training and yours for my PLCs.
PART 1 was fantastic,let me try part2...Hope I understand this too..
AMMMAZING👐👐👐👐 Thank you so much, you're a beyond amazing video instructor. Thank you for the videos. Very very much appreciated.
Very well presented, Thank You.
Now that's what i call a professor !!!
Thank you.

Thanks so much professor and the entire audiences!
Thanks God for your detail tutorial about this matter.
HE is the one who gave it to me...
Teach by repetition. Great teacher, only way I could grasp some of these concepts.
nice work! keep on your good work. very fascinating!
Thank you sir , very good explanation.
You are welcome
Thank you professor it is a grate explanation, I going to kip washing until learning and programming.
Great Lecture, thank you Sir! One thing that was never explained (or maybe I didnt hear) is what does OTE means.
Excellent Presentation
Thank you! This classes really help me out.
I just can say . god bless you.

As a person who has dabbled in programming from time to time binary and hexadecimal are the ones I understand the most.
Yes, you are correct. Unfortunately I normally mention to my classes that this is a representation and not a warranty of actual electronics.

I just thought of a solution, I will make a note to myself to add a note on that section to mention the same. Thanks for the feedback, it all helps. Again, thanks...
Thank you so much you make it really easy to understand
Thank you, thank you so much for these clear explanations.
@plcprofessor Thank you! It's nice that you encourage to make brakes that's very helpful
Good video. Helped with the addresses being on or off.
It is correct, and I go on to explain why people confuse the input device state with the symbols in relay ladder logic. DO NOT THINK relay contacts when you are analyzing RLL. The NO symbol is true if the bit in memory is ON, the NC symbol is true if the bit in memory is OFF, True if On and True if Off are the symbols in RLL, not Normally Open and Normally Closed.
Nice intro lectures (both parts 1 & 2). Thank you!
Awesome video professor!😁
Glad you liked it!
