<div class="markdown_content"><p>Hopefully someone who knows sees this and can help. Unfortunately I don't have any experience in what you're trying to do so I just have some generic help, as well as what I've dug up doing my own google search.</p> <p>My first suggestion is to look on the <a class="" href="https://help.codesys.com/" rel="nofollow">Codesys Help page</a> if you haven't done so already or if Lenze's IDE doesn't link to it. Looking at it myself it seems like <a class="" href="https://help.codesys.com/webapp/_cds_access_cds_func_in_python_scripts;product=codesys;version=3.5.16.0" rel="nofollow">this would</a> be the relevant page within.</p> <p>I did find <a class="" href="https://forge.codesys.com/forge/talk/Engineering/thread/a582b0f360/">this post</a> from someone trying to do something similar.</p> <p>But you might be able to get some help through the My Question button on the <a class="" href="https://store.codesys.com/" rel="nofollow">international store</a> or through a <a class="" href="https://store.codesys.com/codesys-support-ticket.html" rel="nofollow">purchased support ticket</a>. </p></div>
