One page of ST is equivalent to _pages_ of ladder/function block ST is quasi platform-independent - can't copy/paste those _others_ between platforms

[@ShaneWelcher]

Ladder, function block, & all programming languages are dependant on how they are written & what the code is for. That determines the length. Not sure why you are asking about is this equal to that. Code is code, logic is logic, theory is theory. Structured text is a programming language that is widely used in many programming softwares, not just PLC programming. Hope that helps

[@kurtklingbeil]

@@ShaneWelcher my main point is that ST is compact and portable across platforms No matter how complex the overall program, it will take way more rungs of ladder than lines of ST, and each line of ST occupies only 1/4 of the visual space of a rung... Functional Block can leverage the power of replicating a complex block of code a bunch of times

[@ShaneWelcher]

@@kurtklingbeil Yes, structured text is strong...however, it is a complex use for most people learning PLC programming which is exactly why I am trying to teach them & help

[@lonewolftech]

@@ShaneWelcher I can tell you from someone who’s in industry as a tech structured text isn’t used often and when it is it’s a cluster fuck to repair so we don’t use it and avoid anything with it. All our brand new equipment is all ladder so teaching them ladder is far more important first before they learn anything else. This language will NOT get you a job anywhere without knowing ladder fluently.

[@ShaneWelcher]

@@lonewolftech Depends on where you work. Structured Text is highly used in the paper industry. And with Rockwell Automation, it is used quite often. Please don't cuss on my channel when you have an opinion.

Hi l am looking chiller sequence ST program . Sequence incude based on load lift up and down equipments, equipment ranking and based on fault changeover equipment. Can some one help and support

[@ShaneWelcher]

Help with what exactly?

Many thanks from Brazil.

Hey Shane! Yes I agree with you, structured text is awesome. When I learned programming, I learned ladder - but you can’t do everything in ladder very easily. Like examining array data. So I ran into situations - how the heck do I do this? When I started to think outside of the box and not limit myself to ladder - structured text code often was an elegant solution

[@ShaneWelcher]

Glad to help, good to hear from you

[@ManuelMartinez-fx6ql]

Shane, what phyton course to start do you recommend?

[@ShaneWelcher]

Depends on what you want to use Python for. I took several course but they were all general, starting from beginner then use cases for advanced but haven't really for one that is niche dependant expect IT. I took David Bombal's courses for some IT stuff I was working on but again, make sure you pick something that has an end use case so the knowledge sets with you. Code with Mosh, David Bombal, a few Udemy courses. My favorite was just jumping in head first with GitHub

[@Markdias1]

Shane, Buying your course, we can download all the examples that you have done?

[@ShaneWelcher]

There are code downloads for examples in the course, however, a lot of the course is build as you go. This way you have solid knowledge

(14:50) Learn and share together....I did look for somebody with this mindset but....hard to find such type of people, at least for me.

[@ShaneWelcher]

Let me know how I can help
