Introduction to Programmable Logic Controllers (PLCs) (Full Lecture)

[@Durfadorfano]

These lectures are amazing. I have a BS in Electronics Engineering Technology and have worked on computers most of my life but mostly on the hardware side. I have now gotten a new job at a local factory as an electronic tech. Pays really well but industrial electronics is much different than consumer electronics.. Your courses are invaluable to me in relating the two footprints into my new function. Thank you.

Today I had cause to look into the history of the PLC only to discover that Dick Morley, Father of the PLC, passed just this last October and that Jan 1, 2018 will be the 50th anniversary of the day he penned the outline of what became the MODICON by the end of the year while nursing a hangover.

[@edschoenecker9470]

Hi, Jim. Thank you for sharing your knowledge and experience with the rest of us. If you could, I wonder if you would be willing to extend your generosity a bit further? I'm a Maintenance Tech/Industrial Electrician in the Chicago-land area. I'm looking to expand my skill-set/resume to include PLCs. However; I'm finding it difficult to nail down an in-person course to attend. As a Maintenance Tech, I have some familiarity working around "PLC peripherals", as I refer to them, but I have no experience with programming, editing, or otherwise maintaining a program. If you have a suggestion for a class/seminar, I would greatly appreciate it. I'm hoping to find one of the "boot camp" type classes that may be a week, or two long. I'm happy to travel where I would need to. Again, thank you for the wonderfully informative videos. If you do have a suggestion on a course, I thank you in advance for that, as well.

[@bigbadtech]

I do have a bunch of new PLC material planned but it's WAY in the future. In the meantime I'd check out solisPLC. A coworker has had some success with their training.

[@Macdiz]

If I could press a button and give someone a million subscribers, I would use it on your channel. Thanks for this shit, for real!

[@bigbadtech]

Thanks for the kind words. Do me a favor and let your friends know this resource is available!

[@Macdiz]

Jim Pytel I hear people asking for PLC and ladder logic videos and stuff on reddit.com/r/plc quite a bit, do you ever post there? This is a much better resource for a beginner than some of the stuff that those guys recommend, IMO at least, so I'll definitely tell people on there.

[@isaiahongonga3136]

I liked the tutorial. Big up

Hi Jim well-done I have learned alot. Thanks

I hate learning.

"I'm sorry, did I just blow your mind? ...Never have to rewire the system" Me, a mechanical engineer with no traditional electrical wiring experience: ah yes I see the computer is made out of computer Sarcasm aside these lectures are incredibly helpful for me in my career in automation right now.

For those wondering how computers or CPUs work on the electrical signal/binary level, here's a great playlist that really helped my understanding of what's going on in the background of CPUs and memory storage: kzbin.info/aero/PLowKtXNTBypGqImE405J2565dvjafglHU If you apply it to PLCs, you'll see roughly HOW the CPU "makes the decision" of what signals go where

[@bachirghendir4479]

Very good explain put if you have formation about programming completely plc

The best advantage of PLC over hard-wired relays: PLC is more fun.

[@jolyonwelsh9834]

I have only worked with hard wired relays.

[@wisconsinfarmer4742]

A-lot of people here are industrial maintenance people. Lets share pay, job title and years of experience. I’ll start. Title: Controls and instrumentation technician. Experience: 4 years on job in current position, 4 years maintenance mechanic/multi trade /electrician. 1 year college, no completed degree or certification. Pay: $36.98 Year: 2024

[@Mo-ti8ym]

im a mechanical engineering student... what is the minimum knowledge or courses must b taken before this course?

[@bigbadtech]

In a perfect world you would finish the entire basic electrical circuit analysis series (DC, AC, 3 Phase AC) and the motor control playlist ... however ... time may be a limiting factor. At the bare minimum I'd recommend at least paging through the motor control playlist: kzbin.info/aero/PLdnqjKaksr8qRPCFkU2Q8XQe0bfo99rs6

[@jean-claudenjeckforty4757]

Thanks for the video, it was educative. But the link is broken, when clicked on it they say page not found. Thanks once more

[@bigbadtech]

Yes, we're having some website issues at the school. Let me get in touch with our IT guy.

[@jacobcrawford2738]

The link for the study guide works but once you actually click on the study guide itself, it says page not found.

[@bigbadtech]

Thanks for letting me know. This isn’t the first time this has happened. Let me check w the school’s web guy.

[@johnware5312]

Basicly the same deal as program a eeprom.. Just done differently. Personally I think the make and brak symbyols are logically reversed... visually if there is NOTHING between the 2 vertical lines on the diagram its VISUALLY open and that arrow there VISUALLY shows connected...

[@michaelattai7390]

hi Jim. please i need certification in PLC. Please do you offer online certifed program on PLC?..... Advice me on my way forward please.

[@bigbadtech]

Sorry but I don't offer any formal certification. I do have a PLC playlist at: kzbin.info/www/bejne/j2axmIiZlMmroqM however it's still in development. There are a lot of PLC certification programs however I don't think there is an accepted industry standard. I'd recommend seeing which certifications are necessary for your particular industry and contacting these programs directly.

[@nikhilshere2682]

can u tell me types of relays ,transistors uses in plc?

[@bigbadtech]

Electromechanical relays and solid state transistors commonly make up the output elements of a PLC. When commanded to do so by the internal program these output devices will selectively enable output devices.

[@nikhilshere2682]

can i do some crash courses in this and which are they?

[@bigbadtech]

This playlist is still in development: kzbin.info/aero/PLdnqjKaksr8qxlMYRVTF2YzTm6RwtA7pc One day it'll be a complete course.

[@montyedgar6409]

Jim Pytel Your comment was two years ago. Is it now a complete course? Too, I just found your videos recently, and have been listening every day since! Thank you for putting these videos together!!!

[@bigbadtech]

@@montyedgar6409 Glad you're making use of these resources. Unfortunately, no the PLCs course is not finished yet. I've been finishing up the basic electricity and electronics series. Once this monkey is off my back my hopes are to return to PLCs and motors/generators, industrial wind power, and solar. Stay in touch! Until then here's all I've got for PLCs: kzbin.info/aero/PLdnqjKaksr8qxlMYRVTF2YzTm6RwtA7pc

[@SirFency]

OK I'm noticing something here that is kind of confusing. When you talk about an open circuit it usually means that there is power running through it. However in Ladder Logic it seems to be the opposite. Is this true or are people just using the open and close term incorrectly?

[@bigbadtech]

In electrical terms "open" means no path for current to flow whereas "closed" means a path is available for current to flow. For clarification maybe check out the "Switches in Series DC Circuits" lecture at: kzbin.info/www/bejne/pmqZpat4gpt6jas and "Switches in Electrically Controlled Systems" lecture at: kzbin.info/www/bejne/e3-mlYOpdp6DjsU

How Is This A Programming Language This Is Just Simple Electrical Circuits!

[@bigbadtech]

True dat! Ladder logic (LAD) programming language was specifically developed to look exactly like hard wire relay based ladder logic circuits. I hope cover other programming methods like sequential function charts (SFC) and function block diagrams (FBD) in later lectures.

[@jordangourley3955]

None of the pro plc talking points are correct except maybe the fact you can alter process without rewiring. Now that I have been working with both PLC and hardware relay control systems for years, I can tell you I prefer the old way. PLC hardware fails before relay/contactor wiring. It’s more expensive when you factor in the licensing requirements that almost every manufacturer implements to utilize their processors. The PLC manufacturers are deliberately building processors that are incompatible with previous generations of hardware/software (planned obsolescence). Got a single anolog input module that went down? Oh sorry that module is obsolete, you’re going to need a new processor, as well as all new modules for every rack slot. Bruh this shit is only 3 years old and it cost 50k to integrate and install. So on and so forth. Remember kids: Relays, contactors and starters are open source. And they’re open source forever.

[@bigbadtech]

Trust me I do feel your pain!
