<div class="markdown_content"><p>Hi, I have the same problem with the symbol configuration from Codesys V2.3. I have a PLC from Wago 750-880. Im not sure why the Codesys HMI cant read the data from Codesys 2.3. What Ive notived the difference between Codesys V3 and V2 is the <strong>.xml</strong> (Codesys V3) and <strong>.sym_xm</strong>l (Codesys V2) for the symbol configuration. I think because of this sym_xml file, the Codesys HMI cant read the values from Codesys V2</p></div>

<div class="markdown_content"><p>Hi,<br/> hm.. you write:</p> <blockquote> <p><strong>Zitat:</strong><br/> '- I simulate the PLC with Codesys v2.3.'</p> </blockquote> <p>this is the point I guess.<br/> You need to use a real plc, even if it is running under Windows for example PLCWinNT which is part of the CODESYS V2.3 installation .<br/> Then it should work</p> <p>BR<br/> Edwin</p></div>

<div class="markdown_content"><p>Hi everyone,</p> <p>I'm trying to make a little proof of concept with this setup:</p> <ul> <li>I make a silly program in Codesys v2.3 with an XC-CPU201-EC256K from EATON as Target.</li> <li>I simulate the PLC with Codesys v2.3.</li> <li>I make a HMI project with Codesys Development System v3 in order to create a visualization of the PLC that works with Codesys HMI SL (like shown in this webinar <a class="" href="https://youtu.be/mIvH7L6U5P0" rel="nofollow">https://youtu.be/mIvH7L6U5P0</a>).</li> </ul> <p>But I can't add the PLC as Datasource to the HMI project. I've tried changing the Communications Parameters but I don't know how to link the simulated PLC with the HMI project.</p> <p>Here you can see two screenshots of the situation:</p> <p>I would be very grateful if someone point me in the right direction.</p> <p>Thank very much in advance for your help.</p> <p><img alt="IMG: Bild" rel="nofollow" src="http://i64.tinypic.com/x25ixu.jpg"/></p> <p><img alt="IMG: Bild" rel="nofollow" src="http://i65.tinypic.com/jt0uc0.jpg"/></p></div>
