title: Beckhoff CX9020 - Can't establish a connection with TwinCAT 3
body: <p>I've got a <strong>Beckhoff CX9020</strong> module with the following informations (as seen in <em>General</em> Tab in the <em>CX Configuration Tool</em>):</p>
  
  <p>System Information:</p>
  
  <ul>
  <li>Device Name: <strong>CX-xxxxxx</strong></li>
  <li>Image Version: <strong>CX9020 HPS 5.02d</strong></li>
  <li>CXConfig Version: <strong>1.0 (Build 73)</strong></li>
  <li>CPU Frequency: <strong>1000 MHz</strong></li>
  </ul>
  
  <p>TwinCAT:</p>
  
  <ul>
  <li>Version: <strong>2.11</strong></li>
  <li>TC Build: <strong>2254</strong></li>
  <li>AMS Net Id: <strong>5.39.55.247.1.1</strong></li>
  <li>Reg Level: <strong>PLC</strong></li>
  </ul>
  
  <p>Now I have installed TwinCAT 3, but <strong>can't establish a working Connection</strong>.</p>
  
  <p>The questions:</p>
  
  <ul>
  <li>Is it, because there is a wrong Image installed on the <em>Win 7 Compact Embedded</em> CX9020?</li>
  <li>If that is the case, how can I install a newer TwinCAT 3 Image?</li>
  </ul>
