⚠️ *This video took a long time to make* if you would like to buy Paul a coffee to say thanks, link below: ☕

When I worked on a diesel-electric rig I asked what PLC meant, was told "Please Leave Connected". Lol.

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.

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

[hubertcumberdale]

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!

[RajanHeera]

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!!!!

[elcontrastador]

So thorough...I appreciate how long this takes to be so thoughtfully planned and produced. Kudos!

[matheusbatinga]

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.

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.

[felico]

I'm a recent Chemical Engineer working in industry and I found this incredibly useful. The examples you provided really helped consolidate my understanding

[Stasiek_Zabojca]

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.

That third example of the optimizer in the PLC controlling building temperature waa pretty neat.

[warrenscorner]

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.

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!

[Faz]

Hard to find videos like these which explain maximum content in a short span of time with excellent demonstration

[Xoulis]

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)

[Rotwold]

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.

[Shadowwand]

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!

[danielalexander]

Absolutely amazing, I’m a fourth year apprentice electrician and you don’t understand how simple that video is to understand compared to tafe

[lgninjalo]

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.
