Can we used previously developed libraries in twincat also within PLC++?

What is meant by Command Line interface?

What does the IO mapping look like on disk? are they plain text files as well? that would be magical

don't waste your time on this solution. every power restart erases the program from the controller. until they solve this problem it's a waste of time on this fun. I wasted a few days and now I have to start my project from scratch.

Very exciting. I have 2 questions. 1: How do properties change - do we perhaps have the "traditional" auto-implemented properties", or do we still require set/get assign/read a variable? Do we now declare them in text and have get/set accessors more traditional way in the code part (assuming yes)? And a sub question is, can you now access properties of structured types directly when doing property access or do you still need to have the property be a REFERENCE TO. Example - IF myFb.MyStructProperty.Value THEN ... - does this compile and work if it is declared as MyStructProperty : MyStruct and not MyStructProperty : REFERENCE TO MyStruct 2: Does online monitoring for methods with return type work? If your method returns an object, sometimes you might want to do a direct access to that object, instead of setting another variable to it. This however does not display correct values when doing monitoring, with either 'call' or 'variable' attribute. Example : If myFb.Method().Value THEN .... - It would be really neat if you can see the .Value online, and just like above, does this need to be a reference type or no? Some little features I would really like to see work. Great video :)

My employer paid about 30K USD for the licenses for me to use Allen Bradley RSLogix software at work. Insane prices.

Endlich plain text code! Der Frust wegen Versionskontrolle auf XML Müll hat endlich ein Ende.

My expectations are growing! Can't wait to test it out for myself. Thanks for the peek!

Great video, very promissing future is comming:D I wonder if it's PLC++ then if it will be possible to write "nCounter++" instead of "nCounter := nCounter + 1" ?

Why Germany? Why do you have to make life so hard?!? -Jakob Sagatowski

Currently, what annoys me in TwinCAT are properties (get/set), specifically that if you want to see their value online, you have to add a pragma to each one. Please, Beckhoff Jesus, make it so this isn’t necessary in the PLC++ 😂

There is one thing where Siemens stands out as better than Beckhoff: DB (Data Blocks). I’m curious if Beckhoff has done anything about retain/persistent variables. Siemens has the snapshot option. It would be great if it was possible to export/import the current values of variables.

I don't think they are loosing money because of the performance classes, I think they are advancing from manufactures using classic CodeSys

The mini scope blown my mind! I loved it, I can not describe how long it takes to make a good scope for commissioning, that is well organized, this will save me a lot of time to be able to see what's going on with a fast state changing boolean

so I can declare new variables as an online change now without having to hope the PLC won’t crash?!? FINALLY !!

Would like to know if I can run TC3 on an Apple silicone running a windows VM? Or TLinCAT?

Will it be possible to configure IO trees, all the terminal CoE and EtherCAT settings, and stuff like that in text files as well? Or only the things under the current PLC node in the configuration tree?

Can you install it on an ARM laptop yet?^^

Ich bin von der Siemenawelt auf Twincat umgestiegen. Beckhoff ist so wunderschön ❤❤❤❤ Ich liebe es❤❤

Great video, thanks.

I have only just started watching your awesome series of videos and it’s disappointing to learn how closed minded the industrial PLC software industry is to open source. I am a Java developer and I cannot imagine how terrible I would be if I was not able to study the code of others. As you have pointed out, if you don’t see what others have done, then you get stuck at the top of mount stupid. Developers need to be humble. There is always much to learn. There simply has to be a ton of PLC code out there that is rubbish and that would be better if there was an open source approach to sharing of knowledge. The PLC guys that want to keep their code to themselves are misguided, stubborn and wrong. Jakob, I see how frustrated this closed mindedness makes you and how passionate you are about being an agent of change in a field you clearly love and have a gift for. I think the flood gates of knowledge will open in this industry and when they do, the outcomes will benefit all and bring PLC programming out of the dark. Thank you for your sharing of knowledge. The world is a much better place with people like you in it!

Hi! I notice that many companies are switching to low code platforms for PLC control software. Currently this is based on external software like Cordis Suite, I think it would be interesting to see how PLC++ works together with such tools. I am also curious if Beckhoff is also planning to make their own low code solution or if they continue to focus on 'traditional' programming.

Thanks, Jakob. I have a question: As I understand, there are some changes in encapsulation, which means I won't run my old codes without any modifications. Am I right?

Thanks Jakob

Very interesting development. I don't get very deep into the technology behind TwinCAT, but it doesn't take much to quickly realize that some aspects of TwinCAT are very clumsy. Git is one of them for sure so this is good news. I only watched 17 minutes, I'll watch the rest tomorrow, buT I am very curios about potential performance improvements with online operations. Thanks for keeping us posted on things TwinCAT.

What I want to see from Beckhoff is to still see plain text code in the repository even when encryption is enabled via software protection. The files should only be encrypted when the files are built and created in the boot folder.

Oooh! I wonder if you can use VS packages now. In the past I tried using emacs keybinding for VS and it does not work. You can still install the vsix package fine and dandy but no function when trying to manipulate st code. My hopes are up! Thanks Jakob.

Over priced

This is promising, thank you for the video! I want to see more of the CLI functionality, how can we build, how can we run unit tests?

That looks very good! Some questions you might delve into in future videos -Is building / downloading a lot faster? It does seem so in your video or have you edited out waiting times?. At my work-laptop for example loading the plc project I'm working on already takes 55+ seconds (first time loading after windows boot, loading again is quicker but still slow... (not as bad as TIA..). -In twincat-classic I'm using method's like fb_init() does that still work? -do attributes still work? For example I use: {attribute 'to_string'} for my state enums and then I can do in code To_String(myState) and use that for logging -Could you have declared the enum inside the function block and would it then have local scope? -will it be in twincat 4026 which is stil fairly new? I'm lookin forward to try this new plc++, meanwhile I'll have to do with your video's which are very informative!

Jakob, such a great Video, really enjoyed it, especially the Z / Y rant!!! :)

What about the pragmas? Does plc++ has alternatives to that? For example, to check if the function block input is connected or many others that are highly useful.

Another great video, Jakob. One question: In PLC Classic you could make a basic visualisation (codesys). That option is gone i assume? Using PLC++ the only options for a visualisation is Twincat HMI?

Great video Jakob. Isn't there a coincidence between properties and VAR PUBLIC? Isn't VAR PUBLIC identical to a Property with GET,SET

@Jakob: I think you already know, but... In german a Y is a less often used character compared to a Z. So it is banned to a place near the corner of the keyboard. 😉 But I can fully understand your frustration about german as a foreign language. 😂 Keep tryin.. 😉 And of course a big Thank you for all of your work during the last years! 👍

42:00 iam fairly certain this works in the current XAE as well

I think this is codesys go under the hood and they didnt really develop a new runtime from scratch. Which is fine, in my opinion nowadays having the supply chain crisis in mind its a good thing to have code and programs which are to a degree portable. Breaking that would also mean bechhoff programs would be not anymore be supported by codesys. Supporting 2 runtimes in parallel would also be quite an effort from library side and they would have to reimplement all the default libraries from codesys (assumption is codesys would not hand them out the source code), that would be insanse as it would take years to have the same runtime behaviour. Beeing able to mix them further prooves my point. That said even do i think this is a good thing it renders the first part of your video misleading as we dont really now how its made under the hood.

Very cool Jakob, Thanks!! I am a C# developer and I have just started using TwinCAT. We are a pretty formal house and use GIT and JENKINS. TwinCAT is a big improvement over other PLC languages regarding formal development. PLC++ looks like another step up from that. We currently do most of the operational code in C# and use the PLC (mostly) as an IO front end. It this continues, I can see more code moving to the PLC. BTW, I contacted Beckhoff US today and asked when PLC++ will be released and he said market release is targeted for Q4 2025.

Great video Jakob. As I understand it, now that variables, DUTs, methods, etc can all live in a single file, it should be possible to just use VSCode for the coding part. Maybe even for PLC and tasks configurations. Would love to see a full VSCode integration. As a Codesys North America System Partner in Canada, I've been using TwinCAT and Codesys for many many years but never really liked the VisualStudio integration and prefered working in Codesys IDE. Visual Studio just feels too heavy. I really love Beckhoff PLC++ new features and hope Codesys will have some similar features in their upcoming Codesys Go. Keep up the good work.

Very very nice, but i have some questions and comments: 1. If Beckhoff develops a completely new compiler, will it be 100% compatible with old, especially for non-standard things features __NEW/__DELETE, __TRY/__CATCH/__FINALLY, __POUNAME, and so on? 2. Will new compiler/language support type introspection or even reflection? 3. Will there be any new features in the programming language, such as constructors/destructors, generics, string concatenation with + and long strings support, arrays of variable length, method overloading, etc? 4. I don't understand why default function block/program method does not have own subblock, something like IMPLEMENTATION ... END_IMPLEMENTATION. I don't like how it's currently made, blocks are mixed with code...

Rewelacja Kubusiu❤❤❤gratuluję ❤

Hi Jakob. Great video, thanks. Do you know anything about a TwinCAT API to automate engineering tasks or if there will be similar feature in the future? Something similar as TIA Portal Openness for Siemens.

Great video! This looks like a giant leap forwards. Would you consider making a video showing how to setup an OPC UA server on a Beckhoff PLC? All the existing videos/guides that I found seem outdated and no longer work. I couldn’t figure out how to do it myself.

Dear Beckhoff Jesus, would love if you could check out the graphical languages aswell. We know its not your area of expertice, we just wanna see a preview of what is to come, thanks! 😁

Jakob, you are doing a fantastic job. Thank you very much! The automatic synchronization in German works amazingly well. I think you'll be happy to hear that. However, I have set the playback speed to 0.8, which is very pleasant. It's probably because German is longer in expression. Keep up the good work!

Jakob x Beckhoff, great partnership. When I first started using Beckhoff, the documentation was frankly terrible. They've improved the documention for individual libraries and functions massively such that its now miles ahead of other platforms, but I think they still struggle with explaining higher level concepts such as how to strucutre projects, etc. These videos are a great way to fill that gap, great stuff

Hello @Jakob, congratulations on your videos and happy new year 2025 .🎁 Is there a Beckhoff link where you can ask to be a TwinCAT PLC++ beta tester? I would really like it if you could make videos of TwinCAT RT Linux installed as a docker, podman or LXC container...👍 💯

The thing with the German Keyboard is really funny :D

I can't wait for your deep dives and tutorials for plc++. I'm a little disappointed that they are building it on VS. My question is can you simulate physical inputs/outputs between parallel plc programs? Say you had a complex machine and you wanted to simulate failures and/or wierdness with physical IO before running it with real hardware.

❤️❤️❤️❤️
