<div class="markdown_content"><p>Hi,<br/> by default this is added (qualified-only) if you add a new GVL.<br/> If you remove the attribute it will work without.(would not recommend)<br/> But better style is to use it. <br/> Not declaring Enums and GVLs qualified_only may result in ambiguities, unintended shadowing and potentially other problems. These problems could be simply avoided if enums and GVLs were decorated with the attribute by default. <br/> This would also improve overall code quality, readabilty and explicitness. <br/> This is since SP8 default.</p> <p>BR<br/> Edwin</p> <p><img alt="IMG: qualified" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=1784"/></p></div>
