<div class="markdown_content"><p>Not possible.<br/> I have 3 HMI devices from different manufacturers using Codesys runtime versions 3.5.12, 3.5.10 and 3.5.7.<br/> So I will have to wait for years until the manufactures decide to update the runtime to a version that can be used with the version 3.5.14.0 of IOT library.<br/> It's real problem with many libraries available in Codesys store.</p></div>

<div class="markdown_content"><p>Thank you for detailed explanation.</p> <p>My controller uses Codesys 3.5.12 so now that the INI file utility is part of the IOT library and requires V3.5.14.0. <br/> Can I still use the 1.0.0.1 of the INI file utility or not available anymore?</p></div>

<div class="markdown_content"><p>then probably the persistence manager is probably not the right feature, if you do not want have a persistent state on shutdown..!<br/> you may use:<br/> <a href="https://store.codesys.com/ini-file-utility-bundle.html" rel="nofollow">https://store.codesys.com/ini-file-utility-bundle.html</a><br/> If you just need save some parameter on demand and restore them on demand.</p></div>

<div class="markdown_content"><p>I guess some thing like this should work</p> <p>IF xSavePersMan THEN<br/> PersistenceManager.INST_PersistenceChannel.ExternalSave();<br/> xSavePersMan := FALSE;<br/> END_IF</p> <p>I don't understand the following part.</p> <div class="codehilite"><pre><span></span><span class="o">&lt;/</span><span class="n">channelname</span><span class="o">&gt;</span> </pre></div> <p>In Codesys help it says:<br/> <em>In case of a shutdown of the controller or after “Reset” (warm / cold / origin) the data is stored automatically if the parameter xSaveOnChange is not set.</em></p> <p>What if don't want to save automatically? <br/> Is it possible to disable it?</p></div>

<div class="markdown_content"><p>I guess you could trigger the save from application by using:</p> <p>PersistenceManager.INST_&lt;channelname&gt;.ExternalSave()&lt;/channelname&gt;</p></div>

<div class="markdown_content"><p>The persistence manager allows cyclic and on change saving of the variables.</p> <p>Is it possible to activate saving in application instead of the aforementioned ways?</p></div>
