<div class="markdown_content"><p>I am amazed nobody has replied to this!</p> <p>I am also having huge anominalies with trend in a visualisation, including total PLC lockup. There seems no logic behind this. Sometimes it works, sometimes it crashes, sometimes it does not work at all.</p> <p>I also using a Wago (758-870) so it could be a Wago issue or a CoDeSys issue. I am working through it at the moment and if I find the answers I will reply again.</p></div>

<div class="markdown_content"><p>Hi !</p> <p>(First: sry for my bad english)</p> <p>I'm using a WAGO controller <strong>750-841</strong> with a barometer.</p> <p>Every 10 seconds it measures the air pressure and adds the value in a diagram (trend).</p> <p>Unfortunately the measurement doesn't work when there is activated a trend-file on the WAGO.</p> <p>The value is just 0 but a file is written (i checked via ftp).</p> <p>(Hope you understand what I mean; it's hard to explain when you use a german version of CoDeSys...)</p> <p>Maybe somebody knows the problem and can help me. Thank you!</p> <p>malef</p></div>
