<div class="markdown_content"><p>I have Already the same problem when i'm trying to write data more than 10 times in the same file. In fact, i send my data periodicaly to a file that i configured to have permission of W/R in my CodesysContol.cfg. When the Error occurs, i must reboot my machine to success. It means that the problem isn't realted to a limitation of size, but a problem in the function supposed to handle the file. <br/> totorovic : allow me to know if you've found a solution to your problem. <br/> Thanks.</p></div>

<div class="markdown_content"><p>We changed the path where the CSV file is. From intern memory of the IPC to a USB key.<br/> <strong>We still have this error 'INVALID_HANDLE'</strong>. We must restart the Codesys runtime to clear it. That is a big problem for us because machine is in production.</p> <p><a class="user-mention" href="/u/eschwellinger/">@eschwellinger</a> What do you mean by <em>"this is a security issue not to read/write in the plc allowed path"</em></p></div>

<div class="markdown_content"><p>Thank you for the return. The path targets to a CFast card. User has R/W access to it. We will try to change it.</p></div>
