<div class="markdown_content"><p>It took a bit of head scratching, but the solution presented itself eventually. <br/> In a few cases, I was creating new objects like this:</p> <p><span style="color: #0040BF;">IF ((aux := __NEW(fuzzySetArray)) = 0) THEN<br/> // do something<br/> END_IF<br/> </span><br/> If the object creation is taken out of the IF statement, like this:</p> <p><span style="color: #0040BF;">aux := __NEW(fuzzySetArray);<br/> IF (aux = 0) THEN<br/> // do something<br/> END_IF</span></p> <p>...then the download fault disappears and the simulator is ready to run.</p> <p>Find the corrected (..._A.project) file attached to the first post above. <br/> Jeff</p></div>

<div class="markdown_content"><p>Hi All;<br/> I have been translating the (open source) eFFL Fuzzy Logic library <a class="" href="https://github.com/zerokol/eFLL" rel="nofollow">https://github.com/zerokol/eFLL</a></p> <p>The persistent problem is that, while the code compiles without errors or warnings, the simulator balks at a download with error: <strong>"C0367 Internal error 3 prohibiting online change! Clean application and download necessary"</strong>. Cleaning the application makes no difference. I have been unable to track down the cause of the error and was hoping to find some help from someone who might have a better grasp of OOP principals as applied to CODESYS. There is a possibility of a call to an un-instantiated object, but i haven't found where.</p> <p>An additional question i have is about the CODESYS "NULL" definition. The code compiles with NULLs, but the editor doesn't appear to recognize it as a defined symbol. I have tried replacing all the NULLs with a numeric '0' - this also compiles without errors, but made no difference to the download.</p> <p>Any clues to getting this running would be appreciated.<br/> Thanks,<br/> Jeff</p> <p><span style="color: #0000FF;">EDIT 1: Changed attached file to .project</span><br/> <span style="color: #0000FF;">EDIT 2: Corrected .project file attached</span></p> <p><a class="" href="https://forum.codesys.com//download/file.php?id=4395" rel="nofollow">Fuzzy_eFFL r024_A.project <span><span>[183.92 KiB]</span></span></a></p></div>
