<div class="markdown_content"><p>Hey akrabato,</p> <p>I can't answer your actual question (I'm curious as well).</p> <p>I can help you fix the OSCAT V3.31 Library. This is how I have corrected this problem for myself:</p> <p>1) Download the library from the OSCAT website. <br/> <a href="http://www.oscat.de/images/OSCATBasic/oscat_basic_331_codesys3.library" rel="nofollow">http://www.oscat.de/images/OSCATBasic/oscat_basic_331_codesys3.library</a></p> <p>2)Open the Library with Codesys (I'm using Schneider Electric Machine Expert). It will most likely ask you to upgrade the project. Select Update<br/> [-img src=Step 2.JPG width=75%: missing =-]</p> <p>3)Open the Library Manager<br/> [-img src=Step 3.JPG width=75%: missing =-]</p> <p>4)Right click on the standard library and select "Properties". In the Version section, select the radio button for "Newest version always".<br/> [-img src=Step 4.JPG width=75%: missing =-]</p> <p>5)Save The Project (OSCAT V3.31 library).</p> <p>6)Import the OSCAT V3.31 library to the project where you actually need to use it.</p> <hr/> <p>I have also come across another method of fixing this. Check out this YouTube video:<br/> <a href="https://www.youtube.com/watch?v=ySNp9_Cb6e8" rel="nofollow">https://www.youtube.com/watch?v=ySNp9_Cb6e8</a></p> <p>Skip to around 9:40 to see how he handles the problem. He just deletes the newer "STANDARD" library and uses the older one that comes in the OSCAT Basic Library (V3.3.0.10).</p></div>

<div class="markdown_content"><p>I installed OSCAT Basic Library v3.3.3.0. <br/> When I upgraded it to v3.31, OSCAT changed internal link to Standard library v3.3.0.10 from v3.5.15.10. <br/> And I can't download this old version of Standard library now. (Download missing libraries failed.)</p> <p>It is the common problem after Codesys v3.5 upgrade to a new version or upgrade some libraries. <br/> After that some links to different versions of standard libraries appear in the project<br/> and these libraries don't download.</p> <p>I'd like to understand why this problem happens and how I can handle it?</p> <p>Can some standard libraries be downloaded directly from Codesys Store and then installed manually?</p> <p>Can I read in the documentation about how Codesys handle with different versions of system libraries?<br/> (How does dependency resolving mechanism work? And why may it not work?)</p></div>
