Күн бұрын

In this lesson we'll perform a brief overview and orientation to the programmable logic controller or PLC. We'll discuss the purpose and basic parts of a PLC and discuss different types of PLCs and PLC specifications. Additionally, we'll discuss the differences and advantages of PLCs over traditional hardwired relay based ladder logic. (Full Lecture)

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.

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 6 жыл бұрын

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.

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: kzfaq.info/sun/PLdnqjKaksr8qRPCFkU2Q8XQe0bfo99rs6

Sorry but I don't offer any formal certification. I do have a PLC playlist at: kzfaq.info/get/bejne/j5t-mriUxMrcnHU.html 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.

@SirFency 6 жыл бұрын

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 6 жыл бұрын

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: kzfaq.info/get/bejne/pp9mp9tzspyrh30.html and "Switches in Electrically Controlled Systems" lecture at: kzfaq.info/get/bejne/e7Rzl7Okpp-0iJc.html

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

@bigbadtech 5 жыл бұрын

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 8 ай бұрын

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.
