<div class="markdown_content"><p>Hi Raj,<br/> Can you explain further the blame on "array structure for persistent variables"?<br/> When you double click the exception to go to source position where does it take you?<br/> Which WAGO PLC?<br/> If you go View &gt; Call Stack.. you will see where in the code the error is.</p></div>
