<div class="markdown_content"><p>Bonjour,<br/> est-ce que les espaces de noms des variables sont bien indiqu dans les commutateurs ?<br/> Je viens de faire un petit essai: OK<br/> {attribute 'qualified_only'}<br/> VAR_GLOBAL PERSISTENT RETAIN<br/> xBit1: BOOL:=1;<br/> xbit2: BOOL:=1;</p> <p>END_VAR</p> <p>Déclaration de variable dans le commutateur (et aussi dans un voyant pour le test) :PersistentVars.xBit1<br/> Bon développement!</p></div>

<div class="markdown_content"><p>hello everyone</p> <p>I would like to try to better understand how persistent variables work.</p> <p>I created some boolean variables in the PersistentVars section initialized to the value TRUE.</p> <p>I have tied these boolean variables to toggle switches placed inside the HMI interface pages.</p> <p>Once the PLC program is started, the lever selectors, if operated, change their state, at least at a graphical level, but the persistent variables do not undergo any variation.</p> <p>Initially the above variables were declared as simple global variables, in this case the operation with the levers was correct; I then tried to transform them into persistent ones with the aim of using them as "settings saver"</p> <p>Thank you for support<br/> Bye</p></div>
