<div class="markdown_content"><p>Hello professionals. I am a beginner, learning the codesys environment while trying to run a certain project. I have been stuck for a week over the launch of the communication on the raspberry pi target. I want plc to talk to the adam advantech 4571 module, which is a TCP server. I can't read the help-online page properly regarding the TCP_Client block. Would anyone have an example of a communication running using TCP client -&gt; server? The available tutorials on YT are on older libraries and that doesn't work for me. </p> <p>Going through this problem will allow me to make the final decision regarding the purchase of a license for the raspberry pi :-)</p></div>
