<div class="markdown_content"><p>Hi Everyone, Im recently new to the 61131 standard and codesys, but have 30 years programming experience. I have noticed the standard defines a VAR_DYN block which allows dynamic/temporary allocation of variables (using the stack mechanism). However, codedsys seeems <strong>not</strong> to have implemented this feature, so all variables are static. I have scoured the documentation and the net and can find no references to this.</p> <p>I am using codesys 2.3.6 (i have no choice here). Have I missed something, or has this requirement never been implemented?</p> <p>thanks all</p> <p>simon</p></div>
