<div class="markdown_content"><p>I've only seen an error like that when I'm simulating on my laptop rather than running a test on a real PLC. I think it's related to an inability to save or store info when I'm simulating the PLC. I also get this on an actual PLC if I mange to delete the trend files that codesys has generated. </p> <p>So I would access your PLC's internal storage and see if in PlcPrg/Visu wether you have Application.TrendRecording.xml, Application.NAME.sqlite, and Application.NAME.sqlite.metadata</p> <p>You can access this storage via FTP if your configuration supports that.</p> <p>If those files aren't being created trying doing a fresh install to your device wiping existing PLC data, clean your program, and try installing and running it again.</p> <p>If it still doesn't have those files contact your hardware manufacturer's help line. If they have one. </p> <p>Also of note, your trend will need time to populate with data. If you're trying to view it before it has saved any data your PLC may crash or I dunno maybe display something else.</p></div>
