Jakob casually switching between programming languages, then also casually switching between spoken languages to help him better write in the programming languages is incredible (23:30). Well done, as always @JakobSagatowski, and thanks for the in depth tutorial!

Hey Jakob! This series is fantastic! Thank you for sharing this great content!

Great introduction to automation. I use it to create and map all I/O for all our devices, saves a *lot* of time. I would point out that even though theMessageFilter needs to be used, you will sometimes still get COM exceptions ("Windows cannot handle the request because it is busy" or words to that effect) from the Beckhoff methods that should be caught and retried.

[@BalazsBacskay]

According to the Beckhoff documentation the MessageFilter.Register() needs to be called before the COM calls and the MessageFilter.Revoke() after the COM calls (at the end of the program). And the main() method needs the [STAThread] attribute to make the message filtering work.

[@nikolapetrovic5206]

I noticed that too. I tried it in WPF project and I would get sometimes exception even though I implemented filter and Register and Revoke methods.

I had the same issue until I added the [STAThread] attribute before the Main, after that, no more message filter errors. I had missed that little detail the first time around.

Hi Jakob, A great introduction to the TwinCAT Automation Interface. Thank you for this nice Video. The Automation Interface is a very helpful tool. We use the Automation Interface with PowerShell to automate our system tests. And we use it within Azure DevOps for the build pipelines.

Hi Stefan! Thanks for your feedback. Would love to see your automatic system tests one day!

Hello Jacob, I made a plc program I start but I also like to automatically login en start ADS, so I can read and write the variables in the PLC program. Is this possible maybe an configuration in the PLC?

[@manasnagesh9351]

Hi Jacob, I get an error for part 16. Which is the " type of namespace name 'ITcSysManager' could not be found. I have added the required libraries. Could you please tell me what i might be missing".

[@darkxceed]

Hello Jakob, I really love your tutorials, it helped me a lot. At our factory we test products which contain a beckhoff PLC. I think it would be very helpfull if you could send me the .exe from tutorial 16 or can you tell me where I can find it? Keep up the good work!

@@JakobSagatowski is there a way to programmatically add a route?

[@MrPcwortex]

All of this posible to do with Python language?

Hi Jakob, This series is helping me out a lot in understanding TwinCAT3 3 programming! but i'm strugling to get the automation interface working, since today my project keeps giving an InvalidCastException: "Cannot convert COM object of type System.__ComObject to interface type TCatSysManagerLib.ITcSysManager15." Do you know where this is comming from? it occurs on this line: ITcSysManager15 sysManager = (ITcSysManager15)project.Object;
