Great video!
Are you considering (or do you already have made) a video on PID control?
That'd be awesome! Greetings from Spain!
Great video, thank you.
Soutwoods city
I'd love a video on the PID loop as well. I'm struggling with wrapping my head around tuning, and I seem to keep getting the Ziegler-Nichols method wrong.
Hello everyone 🙌
When I worked on a diesel-electric rig I asked what PLC meant, was told "Please Leave Connected". Lol.
🤣
😂😂😂😂😂
hahahahaha
The fact you got to work,on diesel rig and had to ask what a plc was says everything
@@chrisyboy666 considering most diesel rigs don't have them your comment says everything.
I watched the whole playlist on, " The Electrical Engineering Basics," and I thank you Paul for the visuals and the accompanying explanations that make this subject much easier to understand. Your videos and playlists are well done; Keep up the outstanding work! I look forward to increasing my learning and understanding through your other playlists.
This guy is a GENIUS teacher....
Another advantage, or disadvantage depending on which side you are on, of PLC's is the ability to download a virus and destroy your adversaries centrifuges. Excellent video and great animation.
References XD
“No more enriched uranium for you today”
I try my very best to avoid connecting my PLC projects to a network unless I absolutely have too, and even then I use something called a VLAN to isolate them from the wild wild west (er, I mean internet). Even then, if someone REALLY wants to break your stuff, I can imagine a virus that infects your computer, and then eventually infects your PLC when you connect via USB (or other) to push an update. In the real world, security is never 100%. Its a function of how much money and time you spend defending your system divided by how much someone malicious is willing to spend to break in!
That actually depends on the way it is integrated.
and people wonder why they hate us
I would like to see more about PID
I am too
Right! Me 2
Don’t take that brief explanation on current, past or future. Not exactly what they do and the whole goal is to reduce cycles or constant changes

Super cringe to act like you're the one making these videos.
"Thanks for the input."

@@tannerholmes1587 Thanks for the input
So thorough...I appreciate how long this takes to be so thoughtfully planned and produced. Kudos!
I love you. From now on, I will worship you. I literally have an exam next week on PLC's and because of the pandemic, we didn't have a lot of time to work with them. Thank you so much for the informative video. Keep up the good work!!!!
Awesome content. I'm a beginner in the field of industrial automation and your videos are a must watch for me and my colleagues; I always share the videos with them so we can discuss. Thank you very much for the high quality content and please keep posting.
I just started an electronics programs at a local tech school. I can not thank you enough for the videos you make. They have been directly related to the material I am learning and have definitely been a study aid for tests. So thank you for walking people thru the magic of electricity and helping a noobie like me learn!
Send us some questions when you have a chance!
@@rylandallas9907 I’m also in electrical engineering tech school
This is more electrical than electronic dude
Values from sensors / actuators is almost never taken from 0 volts or 0 mA etc. The standard is 4-20mA. It's due to the risk of not knowing whether for example a temperature sensor is reading correctly or if it's faulty. Always passing current to the sensor is a simple and effective way to avoid the problem.
i just wrote the same and read this after, lol :D
As someone who works for Siemens this is not true
@@stevenurban5909 wtf are you on about? 4-20mA is a safety feature...need a live zero mate otherwise how do you know if it's fucked or on 0? If it's reading 4mA, you know it's not fucked and the sensor is on 0
@@chilipalmer2195 looks that way 😂
Ok I'm dumb but basically you're saying minimum 4mA to ensure its ok and 0 signifies faulty right ?
I loved to program PLC controllers in school! Those things are so awesome. When I got bored I started to make some music with relays on/off sound by making it switch in the right time.
Let me guess: Now you work for a relay manufacturer to build his stand at trade fairs like the Hannover Messe. Every single relay manufacturer there did exactly this with teir relays.
@@KarlKarpfen No, not really. Programming CNC machines and making things on them is more interesting thing for me and that's the way I chose. But sometimes I miss programming PLC's.
Where did you go to schook to kearn PLC? And programming them
@@Slimbo_85 Technical school in Poland, mechatronics.
@@Stasiek_Zabojca interesting. I'm doing mechatronics right here in Kenya and will be learning PLCs
I am an apprentice in the United States and I just want to say that these are the best videos I have ever watched. Thank you for putting these together and making them easy easy to understand. They Are actually priceless when it comes to growth in in my field and that is amazing
Talking about old electrical substations, had a fellow apprentice when I was young who was careless with his elbows and blacked out I guess about a thousand homes by slightly bumping one of these old mechanical relays, was hilarious to me because well, it wasn't me. :D
I dig this video. As usual you are spot on. I would just like to mention that the PLC scan cycle can also be asynchronous, where the outputs are turned on as soon as the rung preceding them gets a logical true, rather than after the execution of logic. Logix5000 controllers are asynchronous, for example, while Productivity controllers are synchronous. It can make a pretty big difference in your logic and lead to undesired results, so it is always worth finding out which type of scan cycle your controller has via the manual or a call to tech support.
That third example of the optimizer in the PLC controlling building temperature waa pretty neat.
Thanks for breaking this down so well. Too often education gives definitions that are only understood if you already understood it to begin with. Thanks again.
Hard to find videos like these which explain maximum content in a short span of time with excellent demonstration
Glad it was helpful!
I work as a maintenance technician at a food industrial plant. They basically gave me the responsibility to take care of our two new robot tray stacking a product unloading devices. A company controls engineer for the robot's manufacturer help me realize changing code for a machine that runs on more than 2 axis takes a lot of knowledge and patience. I have a ton of respect for these automation specialist!
Are they FANUC robots?
@@Battttt may as well say that, they were made by Schneider packaging.
@@kirkjackson3306 haha chill out im just wondering whether youre gonna have a shit time or not 😹
@@Battttt I'm chill I was I just answered you question
There’s always another to our god complexes 😂 those guys are too smart
I'm a former aluminum smelter production worker. I worked around industrial equipment and machinery that ran off PLCs. I learned how to fix my equipment and machinery by learning how my machines cycled. This allowed me to find the missing inputs or outputs to figure out what was broken and needed replaced to get up and running quickly.
I lost my 13 year career after my plant closed July 2020. There was a news story about how my former planet may reopen.
Ask for a raise!
@@aaronjoseph1777 Why'd it closr
Hawthorne?
My god i cant describe how much i love PLCs. In school i was the only student being enthusiastic about wiring them and programming them ( we used Ladder)
The best video I saw about PLC! Well-explained.Thank you!
4:00 You killed me with the suitcase! 😆
Best way to explain for the begginers and students
Please please continue with these plc videos!!!!
PLCs compared to PCs are more simple, used within industrial tech. Thanks for the video
Wouldn't be surprised if they still used Motorola CPUs in the lower end gear. But yeah they are meant to have just enough bytes to be able to perform it's task. When programming for critical applications it's good to know what every byte is doing in the machine 👍
Depends, the PLCs I'm currently programming are running Win10. The PLC functionality runs in isolated cores. You can have a single device run both the PLC software and the HMI as well.
@@Rotwold or even Z-80 derivatives. It doesn't take much CPU power to check a bunch of input sensors 20x a second...
Absolutely amazing, I’m a fourth year apprentice electrician and you don’t understand how simple that video is to understand compared to tafe
Ty so much for making these videos. I'm a maintenance mechanic looking to step up my game!
Great video! Excellent explanation for someone who knows very little on PLC's.
Awesome! I've always wondered how PLCs work. Thanks!
I love the way you keep it easy to understand, thanks!
Excellent video with nice explanation and examples! One of my favorite channels! Thank you very much!
Really a sound video on PLC introduction...
4:03 That luggage delivery system animation seems about right. The only thing missing is a forklift or luggage cart running over the suitcase to properly compact the contents.
Wish this video was available when I was doing PLC'S in my engineering course.
me2 :)
Same here, I’ve never had it so comprehensively yet simply explained.
Best way to learn PLCs is to just buy one and play with it on your own. Build a traffic light. AutomationDirect has some cheap starter kits to get your off the ground. Overall, PLC programming is like welding, despite what everyone tells you, its not as intimidating as it seems, but then again, theres still a difference between a farmer who welds and a certified, union welder. Its the same with PLCs.
@@michaelmolter6180 how much would a setup cost?
@@imbatman2011 Take a look at the C0-00DD2-D. Its really the most basic, least expensive ($69 + free shipping) option to start with. Youll need a 24 VDC power supply. They sell those (and also one that specifically attach to the PLC if you prefer) or you can get a cheap one on ebay or something. All the I/O is 24 VDC. Another option from the same product line has relay outputs which would be more useful for controlling thing like Christmas tree lights or other 120 VAC loads.
This type of logic is also very common in Scripting like Lua, where Event Handlers respond to changes in input values or states, they perform functions based on other inputs and variables, and produce some sort of result. Excellent video!
Have not heard of LUA before, will check it out - thank you.
@@fevtronx3664 It's implemented in many solid state controllers as a scripting language for parsing Inputs, and I bet some PLC's actually execute LUA Code.
Things like
Create Var Lobby Set Point = 80
Create Function Event Handler Input 1{
Create Var Lobby Temp = Input 1.Value
IF Lobby Temp > Lobby Set Point THEN run Function (Lobby Temp )
}
Obviously that isn't really a LUA Command, but you can kind of see what I'm talking about. And of course the Set Point can change depending on time of day or date etc.
Great. In addition to automation engineering series, could you explain the operation of SCADA and PID in your upcoming videos?
I worked at PepsiCo Chicago with AB 5/40 , 5/25 , 5/15 , SLC 500, SLC 504 , MODICON 984 ,484 . Great machines great, experience !!
very nice video.. hope to see PID, DCS amd SCADA lecture soon sir. Appreciated your effort and the channel as well.
Thank you very much sir for providing us with valuable course of knowledge at our fingertips!
It seems like every time I have a question about something in engineering, this channel has a video about it.
for this I went 4 years to scool. Thanks for the good videos
Very instructive video on a topic of specialised interest.
More than thirty five years back, I have seen industries using CNC machines such as lathes and machining centres, programmed to produce precision components. In some cases, conventional lathes were converted to CNC like capabilities by interfacing with PLC. I guess that programming for producing a precision component must be more complicated than mere climate control in a building.
Great video. Can't imagine how long it took to put this together. One little side note on batteries. You sort of leave the impression that the battery will allow the PLC to function in the event of a power loss. I'm sure you are aware that the battery simply continues to provide power to the RAM memory so that the program is not lost if power should fail. But the PLC would immediately power off. And for some PLCs, the battery also powers the real-time clock so that the date and time will continue to increment while the unit powered down. Again though, great video.
Thank you for writing this addendum, that makes more sense on what the exact roles, limitation and capabilities are for the PLCs.
This is such a great explanation! Thank you
Great explanation of basics for pics. Clearly understood!
Very detailed and informative yet easy to follow.
Your channel is truely amazing. Super informative.
This top tier quality video and explanation as well wow.....
Keep up the good work
Thanks so much am an industrial mechatronics student and this video has helped me alot
Thanks a lot fir such an amazing Video. Found it extremely helpful as an Mechanical Engineer.

Well explained! Thank you!
These are very helpful. We use PLC’s in our Hydrogen Dispensers. Because hydrogen can be so volatile, numerous safety measures, boundaries, limits etc, both temperature, speed and pressure related, must all be controlled simultaneously. Only a PLC can do this!
We are just now getting started on that stuff in my engineering class. Going to be fun to program one to control a robot arm.

I used to work for a process control software company called Intellution back in the mid to late 90s. We developed SCADA software and had a product called FIX Dynamics. I wrote some cool communication drivers to talk to various PLC's. We had a driver toolkit called the OSDK: OPC Server Development Kit and I was the one that put the OPC support in it. I wrote a couple of Allen Bradley drivers, a Modbus driver, etc.
Back in the late 90's I was a software/network engineer working for an automation company. We used Intellution Fix and I think iFix was just released. I remember installing and setting up the OPC Server to communicate with the PLCs. Allen Bradleys mostly, if I remember correctly.
@@clarkdavison4766 That's really cool. I worked at Intellution from 1995 until 2000 (I think). I was responsible for putting the OPC capability in all of the drivers. I wrote the OPC Server Client driver which was pretty cool and allowed us to bring in data from any OPC Server. I wrote both the ABR which was the Allen Brandley RSLinx driver and the ABC which was the Allen Bradly Cyberlogic driver (yes I lobbied hard to NOT call it the ACB driver). I added some really cool features in those drivers and they were able to get incredible performance. I remember talking with one of the chief architects of the RSLinx software and I showed him the ABR driver and he indicated that they couldn't even get the throughput that I was getting because of all of the multithreading and queue optimization and stuff that I designed. Anyway, if you were using iFix and OPC with Allen Bradley then you were using software that I designed and wrote. I hope it worked for you... lol.
I always wanted to learn about PLC's
Please carry on your work 👍
