This playlist is an absolute gold mine and you promote well thought out, clean code which is always a plus

the pointers, references and data type conversions explanation was nice and neat!.. some time ago I struggled with those concepts.

Thank you Jakob for making this tutorial! High quality content.

I wish more PLC developers would watch your tutorials. It would make life so much easier. I have seen so much code that is made up of tons of arrays and they are all over the place. Makes it so hard to read and troubleshoot. Structures are the Bee's knee's. A little planing ahead of time can make the code so much easier to read, troubleshoot and makes it more portable.

Thanks Jacob looking forward for part 6. Everyone in my company is waiting for this tutorials.

Thanks! Part 6 should hopefully be published soon!

Lost it a *contemplating about life* in the closed captions. Chef's kiss. I'm a seasoned vet with Rockwell PLC & SCADA products and have plenty of experience with Wonderware's System Platform, but now getting into the thick of it with TwinCAT and needed something to jumpstart. This series is impeccable so far!

*contemplating about life* ... I love that small brilliant details in subtitles:)

Thank you very much for your videos! I come from the robot sector of automation and start now with PLC/Beckhoff programming. Your explanations help me really a lot!

Very instructive that you show how you search for functions to use and try different things, rather than just show it all done. I also spend more time searching for the best methods than in typing code. I have followed engineers who just hack in TwinCAT, such as copying the same code multiple times, changing a few numbers in each section rather than have a single loop. This was even with code I provided them and said "just add a loop to use it for the 8 units". Then I am stuck having to make changes 8 different places when filling in for them during hurried testing with people waiting. "Ready, fire, aim" is all too common in industry and what managers usually demand to meet arbitrary schedules and budgets.

Watching this course for my bachelor's. Very useful and informative. Also, love the Kraftwerk shirt.

Great! great! content from video 1.....Thank you for this

Tack så mycket och hälsningar från Finland!

Really great content and I love your inspriring comments about software development. I just recently started PLC programming and can confirm the joy of solving problems. Very excited for your next video about FB and maybe OOP concepts? I got a glance on OOP from you TC Testing videos and now want to use more of this in my code.

Thanks !!! Jakob for very useful and content nice explanations ....

Thanks Jakob great content

So instead of creating a copy of DS_Event using pass by value, but we actually just use DS_Event once in MAIN and save the memory without declaring another copy of DS_EventThanks for relating that. Took quite a while to relate it with C++. Because i learn C++ before and this comparison in the video was rather helpfulIt take a while for me to simmer and get it how to use it correctly.

I just started watching your tutorials and couldn't find any more episodes. Then I saw that they were not there yet and it made me sad :(

Great content, Jakob. Coming from other languages where a more functional style of programming is encouraged, it is interesting to me that generally passing by reference is preferred in ST. Passing by reference in other languages would result in side effects and mutating values outside of the function block's scope, resulting in less predictability, especially when debugging. Is the reason for preferring passing in by reference purely because of the real time performance implications of PLCs in controls engineering?

you are the best

I wonder if I could create a function in TwinCat 3 just by typing the syntax into the editing area rather than selecting item from menus like POU here in this case.

When would you use actions instead of methods or functions?

Can you explain the difference between " := " and " => " and why we use one instead of the other?

Hi, I have problem. I have the same code like you but after start PLC the dtTimeStamp doesn't change. I have DT#1970-1-1-0:0:0 and I have no idea how to repair that.

if I write function code without reference so where data of TimestampWithSystemTime going? VAR_INPUT stEvent: ST_Event; END_VAR

Why can't I switch back to run mode after connecting to the Beckhoff PLC🤔

Just do as it says in the message.

Also there is an actual limit to how much you can input (or was at least). Hard to change to pointer once as calling the function crashed the PLC 😅

Hi Casper! A limit of what you mean?

@casperriess6364

A limit on how many input bytes a function (properly also a FB) can have. If I recall I was inputting a massive string array for conversion to byte array. (Might have been a structure, anyway it was crazy big) Then, when it was called it would crashed the PLC. They might have fixed it, it was more than a year ago. But try making a function were you input alot of data and see when(if) it crashes

@JakobSagatowski

Did you input the data as a REFERENCE TO string array? Because otherwise yes, there is a limit that is the limit on the stack size (which is configurable).

is not a bug, is a function!!! hahah Typical comment from an IT, lucky me i am electronic engineer old analogical school .. now i ought to learn this rubbish.. but is entertain. at least it has logical sense,... mostly.

All of the functions here are obsolete and this instructional example is no longer useful. Edited: Turns out it IS working, but the IDE will give a lot of ??? in the function, however, the end result does still work and the D/T Stamp in structure instance does update as it should.

17:48 use Win key+Space bar to switch languages. You even did it by accident 19:25 20:05 you also don't need to google google in chrome lol. Just type in the query directly. You even did 23:09 y google google before haha
