<div class="markdown_content"><p>You may want to look into interfacing your web app to an OPC server. I recently saw what looked like a fairly easy to use Python library that could read and write data from an OPC server.</p></div>

<div class="markdown_content"><p>Hi,<br/> my use case is simple. I need my own HTML5/JS/PHP code to be able to show "current state" of the program running in the PLC. And I also need to send commands to it.</p> <p>It would be great to use it and that could simplify my work a lot, but WebVisu it is not exactly what I'm looking for. I need custom shapes and graphics which are not available. I need a lot of interaction between the Web and other devices (i.e. DB).</p> <p>I was researching a bit and found some ways how to read variables via network (i.e. Modbus).</p> <p>The idea is very simple. Let's imagine a counter that is increasing. I need to show this counter on the Web. How do I read the value of it from the PLC?<br/> Could you please advise me what is the best practise? Which way should I go?</p> <p>Thank you.<br/> P.</p></div>

<div class="markdown_content"><p>Hi all, I'm very new to codesys.</p> <p>I would like to create my own HTML5/javascript visualisation and connect it ("somehow") with the codesys code (to be able to read/send data and calls). Could you please advise me how to do it? I found some articles on the internet, but I'm still confused. </p> <p>Any help appreciated.</p></div>
