Ladder Logic vs. Other Programming Languages: A Comparison

[@Donnner93]

Started my 2 year Automation-Engineer education today, and have been following you guys a while now - Very excited to become one of the people!

[@JKTCGMV13]

3:30 Thank you for addressing maintainability. Too many people don’t think about that aspect of programming.

[@realpars]

Our pleasure!

I have worked as an Automation Engineer for 40+ years. this is a great review and evaluation of PLC programming. Very thorough and truthful. I agree with everything they have shown you.

[@realpars]

Thank you very much!

[@tommyhuffman7499]

Very excited that you made this video! Fascinating topic.

[@realpars]

Glad to hear that, Tommy! Happy learning

I have been working as an automation engineer for almost two years. Our company uses B&R PLCs. We have been straying away from using IEC languages, ladder logic is completely gone with only some structured text still present in some projects. We have almost completely moved to C/C++. I find it interesting how many still use these older languages, I guess it is fine for simple projects. I can't imagine trying to implement something like a neural network in anything other than C/C++. These older languages just can't keep up with the amount computation we are doing for some of these systems from a performance standpoint too. C/C++ also offers control of the PLC at the lowest level, allowing for some of the most dynamic and versatile programs. But with great power comes great responsibility. Anyways I wanted to see if anyone else has been seeing a shift in languages as automation advances.

Thank you for sharing that! Hopefully others in the community can chip in on that.

[@BeeFree_BK]

Thank you and it is really helpful to understand PLC languages~

[@realpars]

You're very welcome!

[@klebermarcio1317]

Your explanation is amazing! Congrats!!

[@realpars]

Glad it was helpful!

[@syufrijal]

Nice information about comparation ladder diagram and other programming languange...very helpful

[@realpars]

Glad it was helpful!

[@matty9217]

Thanks for your coolest videos! It's really helpful.

[@realpars]

You're very welcome! Glad to hear that our video courses have been helpful

[@yukreszi1994]

Hi, can you explain about End of Line Resistor ?

[@realpars]

Hi there, Thanks for your question! It's a bit off-topic for this video, but we have covered the topic a bit in our explanation of DeviceNet. You can check that post out here: realpars.com/devicenet/?fbclid=IwAR12d7sqdLCuBBD1EC0anQXKt4epCUsh41Weqp0hrbItEcx764Y39yHlFOE. Hopefully it helps!

[@876_FIRE]

Clear and concise

[@IngDzib]

many thanks realpars

[@realpars]

Our pleasure!

How does this compare to Frege's logic?

[@realpars]

Hi there, I'm not familiar with Frege's logic. Would you be able to elaborate a bit more?

[@tricky778]

@@realpars it's a historical logic for formal reasoning, but it looks a lot like a ladder diagram. Maybe it's just that both represent some kind of information flow so no surprise they look similar

[@MarsShare123]

Can i know what the meanings as "looping "

[@realpars]

Hi there, Thanks for your question! Looping is repeating the same piece of code multiple times. In PLC programming, imagine that you have to move the value 0 to every element in an array of 100 elements. You could write a program with 100 move instructions or you could write a loop which executes the same command 100 times to move the value 0 to each element of the array. Does that make sense?

[@GuyFromJupiter]

3:30 Careful now! You don't want to upset the true PLC gurus! This is 100% true though. You have plenty of tools at your disposal, and limiting yourself to a single one for all situations is dumb. Use the right tool for the job!

[@shakaranwar2708]

So helpful ❤️❤️ and first comment 😉

[@realpars]

Glad to hear that!

[@johnneenee5847]

Good explanation

[@realpars]

Thank you very much!

[@spacexnix]

I use ST language. It's much more convenient for me.

[@bcar456]

It is not about you, it is about what is suitable for the company.

[@GregoryBirulkin]

Can you make any money at this?

[@mattozx6rr]

Yes and lots of it if you are good at it on multiple platforms.

[@flyte9844]

Great video ! Using the right tool for the right job is the way to go. Don't do math in ladder please 🥹

[@realpars]

Thank you very much!
