Below you will find a list of software that I’ve created specifically for usage with TwinCAT.
TcUnit
TcUnit is an xUnit type of framework specifically done for Beckhoffs TwinCAT3 development environment. It consists of a single library that is easily integrated into any existing TwinCAT3 project. TcUnit tests can be integrated into a CI/CD pipeline using Jenkins. Go the the website for TcUnit.
OSCAT-Basic modified for TwinCAT
This is a modified version of the OSCAT Basic library, so that it TwinCAT can resolve library dependencies for OSCAT. The original is available at http://www.oscat.de/
A precompiled version of the library can be downloaded here.

TwinCAT Library Categories
This is a template for defining your own library categories for TwinCAT3. Without defining a library categories, all your libraries will be shown under the (Miscellaneous)-category in TwinCAT.
Download the template here.

TwinCAT static code analysis loader
All software can be downloaded here.
This is a TwinCAT static code analysis script and program to automatically launch the static code analysis of TwinCAT when commiting code to a version control system. Details about this project are available in a series of posts I’ve made about continous integration/continous delivery (CI/CD) with TwinCAT available at:
The GitHub repository includes the following content:
A TwinCAT PLC project that is to be analysed for static code analysis. This also includes the windows batch-script to be executed by a Jenkins job when a GIT repository change has been detected in the TwinCAT PLC project. This BAT-script launches the TwinCAT static code analysis program described below (TcStaticAnalysisLoader).
A C# .NET program that does the static code analysis using Beckhoffs TE1200 product and reports the result back to the caller as either ERROR, UNSTABLE or SUCCESSFUL which can be used for instance in a Jenkins build slave. The static code analysis is filtered out from the TwinCAT build procedure. This program is used together with the batch-script from the CodeAnalysisDemoTcLibrary folder.
Hi,
Im interested in learning how to use the Beckhoff PLC /HMI software(CODESYS). Are there tutorials available and can this automation software be downloaded for personal use?
Hi! I suggest you look at some of the links, there you have some tutorials.
Sir i am electrical engineer From Madhaypradesh.Sir i have no knowledge about twincat software programming cx 9020 sir plz support me how can I learn programmingbmy many frnd said dont do this and learn but i want learn. I have also knowledge of ther plc delta mitusibishi,omron pls support
Hi! Watch my YouTube tutorial: https://alltwincat.com/twincat-3-tutorial/
ok sir i heartly trying but getting problem
congrats, you made great job with your blog and youtube channel, it helps a lot!
Is there any website than we can find the libraries to download?
Which libraries did you think of specifically?
Hi, Jakob
Thank you very much for your high quality tutorial of twinCAT, I really learned a lot, appreciate it.
I used TIA Portal to program for Siemens PLC, Beckhoff hardware is so complex to understand, Could you make a video about how to configure Beckhoff hardware in TwinCAT.
thx again
Hi! I’ve covered this in part 10 of the tutorial, where I discuss I/O in TwinCAT.
Hi Jakob,
I recently discovered all your TwinCAT tutorials: they are BY FAR the best PLC tutorials I have ever seen! Really appreciate your efforts on this and can’t wait until the next parts are released!
I also admire they way you program in a OOP way, but I’m still having difficulties to see how one can program a complete machine (with motors, IO, …) in a good OOP way. Do you somewhere have an example program of a complete machine?
I might learn a lot of it: how do you do alarm management, how do you deal with parameters, …
Thx a lot!
Hi Jeroen! Thanks for your feedback.
Yes, I know this is hard to come by, and as far as I know there is no example for a complete machine. There are some resources regarding OOP design in my links, as there are some other bloggers that have written about it. This might be something to do a series of videos for in the future. If my videos bring you value, please consider becoming a Patron, which will support me in creation of the videos and will also give you early access to new videos.
Hi Jakob,
firstly congratulations and thank you, your tutorial was the first i found to learn how to program with twincat 3 and was really helpful for me since i had some programing knowledge but from c++.
Now i still learning but for my thesis i got the task to program a DC power supply with Beckhoff components and twinCAT 3 via RS232 (serial communication) but after 2 weeks without results i decided to write you.
firstly, do you know if that´s possible?
we have in the lab a CX5020 and an external RS232 port the EL6002 also from beckhoff and the power supply it is an Aim TTi QPX600DP, i´ve read the manual and that device should be programmable with the RS232 interface with ASCII-code but i couldn’t find any example,
In the beckhoff webpage i´ve found an example for how establish the serial communication, i copied it but i don’t see any change or signal that tells me that twincat recognize the device, i hope you can help me and if you know how to send ASCII-code to the device via that interface i would appreciate it so much. thank you again and greetings.
Hi Jakob.
Many thanks for your experience and tutorials, awsome work!!
I’m trying to achieve a FULL SCM (source control management) environment with Azure and/or GitLab, pipelines, CI/CD, unit tests, Jenkins automation, DevOps and some other analytics, etc.
At the moment i’m in trials phase with some software to see which are the best for my interests.
From your experience, do you have any advice for me? Do you have already some kind of SCM “setup” you use?
I was successfull with you tutorial from TcUnit + Jenkins, but i’m open to another solutions.
The SCM environment that i’m creating, also needs support for Tia Portal (Siemens), but for now Beckhoff first.
Thank you.
Hi there! I’m happy you find my material useful. I’m planning to release a full series of tutorials/courses on this particular topic, so stay tuned!
Hi,
I am trying to learn Twincat3 and Beckhoff PLC, but after installing twincat3 software I am unable to run the program in my laptop(windows 11). I am getting this error;
Severity Code Description Project File Line Suppression State
Error 17/08/2023 17:02:17 956 ms | ‘TCRTIME’ (200): start of real-time avoided by “HyperV”
Severity Code Description Project File Line Suppression State

I tried all the solutions which I got in internet but nothing helped me.
please help me.
You need to make sure that Hyper-V is disabled in Windows.
Bonjour,
Merci pour votre effort!
J’ai déjà utilisé TcUnit pour mes tests unitaires, et là je veux faire des tests d’intégration, vous me conseillez quel outil ? et est ce qu’il existe un outil Twincat Test Manager destiné à l’écriture et l’exécution des tests d’intégration ?
Merci d’avance
Kul att du gillar TcUnit! För att göra integrationstester så får du nog dessvärre utveckla ett eget verktyg. Det finns en hel del små bitar där ute på webben (i termer av open-source), men ingen färdig lösning. Jag ser dock inga som helst tekniska hinder för att göra detta. Lycka till!
Beckhoff TwinCat XAE come in “.exe” extension. is it not possible for it to work on iOS? does it work only on windows?
Only Windows.
