<div class="markdown_content"><p><em>Originally created by:</em> KevinR</p> <p>Hi Martin,</p> <p>I'm still looking for a solution, to get this to work. </p> <p>First of all - Thank you for updating the example. The example still doesn't work for me, during I'm in the online mode. </p> <p>I stay in contact with one of your colleague, who has also added the issue to jira (CDS-54028).<br/> It seems like there is a problem with "read_online_value".</p> <p>This functionality has a very high importance for us. So maybe there are also some other customers who have this requirement. </p> <p>Thank you in advance.</p> <p>BR<br/> KevinR</p></div>

<div class="markdown_content"><p>Hi Kevin.</p> <blockquote> <p><strong>KevinR hat geschrieben:</strong><br/> can I copy all online parameters to the offline parameters with a python script?</p> </blockquote> <p>A device parameter or data element in Scripting has the property "can_access_online" so you can check if it supports the online mode. If it is supported you can read the current value with the method "read_online_value(...)". If a timeout of 1000ms is enough to read the value from the PLC you can use the method without specifing that parameter.</p> <p>Here some untested code:</p> <div class="codehilite"><pre><span></span><span class="k">if</span> <span class="nv">data</span>.<span class="nv">can_access_online</span>:    <span class="nv">val</span> <span class="o">=</span> <span class="nv">data</span>.<span class="nv">read_online_value</span><span class="ss">()</span>    <span class="nv">data</span>.<span class="nv">value</span> <span class="o">=</span> <span class="nv">val</span> </pre></div> <p>I also added a simple python script which prints the parameter tree to the Message view and change the value of one parameter.</p> <p>BR<br/> Martin</p> <p><a class="" href="https://forum.codesys.com//download/file.php?id=2486" rel="nofollow">device_show_and_change_parameters.py <span><span>[1.65 KiB]</span></span></a></p></div>
