<div class="markdown_content"><p>To read or write a file ,you must be carefull of something.The functions all needed a rising-edge to excute.<br/> Also, at the end of the programs ,you should close the file.<br/> I suggest you to use CIA FILE LIB.</p></div>

<div class="markdown_content"><p>I would recommend using the OsCat Network Library it has been tested and validated. It also has a built in File Handler with FB's to read/write variables from files.</p> <p>You have to be signed in to download. This has been updated for CoDeSys V3.</p> <p><a class="" href="http://www.oscat.de/community/index.php/topic,1784.0.html" rel="nofollow">http://www.oscat.de/community/index.php ... 784.0.html</a> m </p></div>
