<div class="markdown_content"><p>ok, I figured out why those data points didn't show.</p> <p>Even though those points were being used in the current HMI they were not being read by the datasource. I selected "Always Update" and they are now being read. Hopefully that helps someone else in the future.</p></div>

<div class="markdown_content"><p>In the screen shots I have the PLC online data and the HMI datasource data. You can see that some of the data in the structure transfered, but not all of it.</p> <p>I'm discovering that the symbol configuration of the data source is not using OPC-UA but a different protocol? Is it even OPC?</p></div>

<div class="markdown_content"><p>Thanks @m.prestel</p> <p>by demo license I mean no license.</p> <p>If there is no datasource limit then why am I not able to read all of the data source variables on the HMI, but I can read them fine with an OPC client? I don't see anything in the log of either the PLC or the HMI that would indicate a problem.</p> <p>The data points exist in the HMI, but don't have the PLC value and if written to from the HMI the PLC doesn't see the change.</p></div>

<div class="markdown_content"><p>Hello <a class="user-mention" href="/u/jtebokkel/">@jtebokkel</a>,</p> <p>what do you mean by HMI demo license?</p> <p>If have no license at all, you get a 30 minutes test duration with no variable limit.</p> <p>Best regards,<br/> Marcel</p></div>

<div class="markdown_content"><p>What is the datasource limit for the codesys hmi in demo mode?</p> <p>I'm having some OPC data points come through, but not all. I'm guessing it might be a demo mode limit issue since I can read all the data points from the PLC via UaExpert.</p> <p>I've got &gt;5000 in the project so far.</p> <p>I tried looking for documentation on this, but I couldn't find any.</p></div>
