Ridiculously underrated channel. I haven't had any formal or professional training when it comes to PLCs, I just sort of picked it up from others at work and seem to have a knack for it. I wrote a program about a month ago and needed like 7 contacts all in series, funnily enough the first thing i tried was the backwards wiring haha made sense in my head at the time but it didn't work on a schneider smart relay so then opted for the virtual relay method. You've got a great PLC series going on. Thanks a lot from the UK.
For decades, the thing that has thrown me off the most about PLA's and PLC's is the terminology. Even the schematics of old EM pinball machines were split into two formats: the actual schematic and the ladder diagram. This is how ladder logic was born. I always found it easier just to write a truth table to a PROM. Then in the 70's we had CPU's like the 6502 or 6800. Now we have Arduinos. Dedicated PLC's seem commercial and superfluous.
i love how you persist and maintain the terminologies used with different things....And not skip from one to another. it sort of embeds it into memory (atleast for me) when i think back on your videos. great channel.. question: the N/C on I1 presents as a N/O contact on the rung.. and the N/O on I2 also presents as an open contact but on input I2. is this correct? how do i diffuse the confusion with these? I'm fairly new to PLC's but have electrical experience and schematics, but this boggles me a bit
Check out the "Basic PLC Instructions" lecture at: th-cam.com/video/ic9crSVVF9Q/w-d-xo.html Long story short there is a difference between the electromechanical nature (ie: NO vs NC) and the programmed instruction (make vs break) and you are free to choose which combination you want.
Everytime time when I think of latching, I would stress on how does I1 which is normally closed gets back to its original state after being pressed to stop the continuity. So thanks for explaining the spring and cylinder process.
I would avoid using 'safety' in any context unless referring to a safety rated system. I still see people trying to use standard PLC's for safety operations. At least explain that this is not a true safety rated system.
This channel really made PLCs easier to understand and much more intuitive
Amazing engineering videos without the indian accent, it's pretty rare to find on TH-cam thank you.
hahaha

Excellent lectures by the way. These are some of the best I've seen.
You my friend are a true wordsmith. For this I’m extremely thankfull
Amazing Lecture! You have amazing teaching skills. Keep up your hard work!
awesome lecture.

Great lecture ty
The contact limit you talk about must apply to programmable relays. I've never seen that in any other PLC unless it's very old.
You did great - thanks 😀
Good lecture. Thanks you
