Hi i'm making my school project ,and i need your help if possible i try to develop a twincat3 project with c++ on windows and have some question if possible .to contact you on mail . Or whats up thanks

Suffered forever to understand the concept of ADS routes, and creating communication routes between a RPi and TwinCAT, until I came across this video! Thanks Jakob

Jakob, thank you so much! The class is getting more and more interesting.

Your work will bring a lot of insights into solving my next problem. Thanks Jackob

Thanks Jakob, your videos help me a lot for my daily job.

Thanks Bruno, and thank you very much for supporting my channel!

Thanks Jacob ! this is extremly good work from Twincat when they make the cross platfrom automation as easy as that.

My pleasure!

Thank you Jakob for the great videos. I have noticed that Beckhoff include "Dispose()" methods in their examples. Do you know if this is required and what is the purpose?

Great video as always. My only gripe with Beckhoff when it comes to the Ads documentation is the lack of info on structs. Basic structs work fine but they don't talk about nested Structs or arrays of nested Structs. When you have a nested Struct and one of the internal structs happens to be an array of Structs with an array of Strings in it the Marshalling stuff stops working. I feel like they really didn't run any extensive tests on complex data structures. I was trying to write a library that automatically marshalls data structures using .NET reflections and ads symbol info. I prefer to use the pack mode 1 pragma on structs and build the binary stream myself using symbol info. It yields safer and better results.

+1 for asking and answering questions on StackOverflow :D

You're leading the way Roald!

Great video, helped a lot! Could you do a video on OPC-UA. I sees it a lot in the industry. Mabey a cool comparison on what easer to use. I am doing that research myself for internship.

Hi Jakob, thanks for sharing, I’m recently researching about this topics, ADS and the Automation Interface, I want to ask you if it’s necessary to use Automation interface, in my case I want to scan the EtherCAT devices attached to the PLC in runtime in other to know whether or not I have to perform some code (POUs) routines, I have read Beckhoff documentation and I understand that I can do it by using C# but what I got it’s that as you presented in this video, it needs to be done from a external hardware (a pc in your case to run C# code) I need to perform this automation task in the PLC itself, is this possible? Am I missing something? I hope you can guide me. Thanks in advance.

Is it possible to use C# library to connect to PLC from a windows machine without XAR/XAE installed ? Similar to what you did with C++ example. I am keep getting Exception thrown: 'TwinCAT.Ads.Server.LoopbackNotRegisteredException' in TwinCAT.Ads.Server.dll when I try this despite adding route on PLC to my laptop's local IP address.

I wonder if we can use the code outside of the ads package we installed, I don't want to exceed a whole package, when I build with g++, I get a missing package error.

Thank you Jacobs!

You're welcome!

Hello, for PLC communication using ADS Webservice do we need to connect internet to PLC?

Is it working on Raspberry pi? Has anyone tried it out?

how to call all variables and each variable with its own value (C++)

Hello, Do you recommend pyAds for Python? Or is there an alternative in Python? Does it have the ability to add a variable's read subscription notification, or can it only be read cyclically?

Hi Victor! I talk about this in the video

Linux works correctly the first time. Why wouldn't it work? Don't do things in the terminal if you don't know bash. Use a simple operating system like Pop OS and everything is stable and modern.

First of all, thank you for all these great videos. I'm having a problem to read a variable using the first c# app you showed. When I launch it from the command prompt it prints "Hello World!" and then it throws an error that says "Target port couldn't be found". I already checked the TwinCAT project and the virtual PLC port number and its the same I'm trying to reach from the c# app, 851 as by default. The PLC program is running just fine and I can ping the VM plc from the HM. Do you happen to know what's going on? Again, thank you for your videos and your help. EDIT: Found the solution! Instead of calling Local on the AmsNetId object, I called Parse and entered the AMS Net Id of my virtual machine like this: client.Connect(AmsNetId.Parse("41.206.230.173.1.1"), 851);
