Dear existing & future PLC software developers, I have published part 15 of my free PLC programming using TwinCAT 3 tutorial.
The Automation Device Specification (ADS) is Beckhoffs middleware to communicate with Beckhoff PLCs. It’s used for all kinds of use cases, as software deployment, reading/writing of variables and for internal communication of software modules. In this part we’ll go through the theory and also write some C# software to communicate with a PLC. We’ll also do a simple C++ program running under Linux that talks to the PLC!
