<div class="markdown_content"><p>Hello, </p> <p>I am attempting to use a python script to add a CANbus device, CANopen Manager, and various CANopen slaves to a project.</p> <p>My script keeps failing when trying to add the slave device. It tells me that "No device found with the following device identification". I have tried creating a device object as well as manually entering the type, id, and version, directly from the device details.</p> <p>I have attached my code and screenshots showing the device details and the error I am receiving. Any help would be appreciated.</p> <p>Thanks,<br/> Max</p> <div class="codehilite"><pre><span></span><span class="k">found</span> <span class="o">=</span> <span class="n">proj</span><span class="p">.</span><span class="n">find</span><span class="p">(</span><span class="s1">'Device'</span><span class="p">,</span> <span class="k">False</span><span class="p">)</span> <span class="n">assert</span><span class="p">(</span><span class="k">found</span> <span class="k">is</span> <span class="k">not</span> <span class="k">None</span> <span class="k">and</span> <span class="n">len</span><span class="p">(</span><span class="k">found</span><span class="p">)</span> <span class="o">==</span> <span class="mi">1</span><span class="p">,</span> <span class="s1">'No object with the name Device found'</span><span class="p">)</span> <span class="n">assert</span><span class="p">(</span><span class="k">found</span><span class="p">[</span><span class="mi">0</span><span class="p">].</span><span class="n">is_device</span><span class="p">,</span> <span class="s1">'Found object is not a device'</span><span class="p">)</span> <span class="n">device</span> <span class="o">=</span> <span class="k">found</span><span class="p">[</span><span class="mi">0</span><span class="p">]</span> <span class="err">\</span><span class="o">#</span> <span class="k">Add</span> <span class="n">CANbus</span> <span class="n">device</span> <span class="k">using</span> <span class="n">the</span> <span class="k">type</span><span class="p">,</span> <span class="n">ID</span> <span class="k">and</span> <span class="k">version</span> <span class="k">instead</span> <span class="k">of</span> <span class="n">a</span> <span class="n">DeviceID</span> <span class="n">device</span><span class="p">.</span><span class="k">add</span><span class="p">(</span><span class="s1">'CANbus'</span><span class="p">,</span> <span class="mi">15</span><span class="p">,</span> <span class="s1">'181015'</span><span class="p">,</span> <span class="s1">'3.5.15.0'</span><span class="p">)</span> <span class="n">can1</span> <span class="o">=</span> <span class="n">device</span><span class="p">.</span><span class="n">find</span><span class="p">(</span><span class="s1">'CANbus'</span><span class="p">,</span> <span class="k">False</span><span class="p">)[</span><span class="mi">0</span><span class="p">]</span> <span class="n">can1</span><span class="p">.</span><span class="k">add</span><span class="p">(</span><span class="ss">"CANopen_Manager"</span><span class="p">,</span> <span class="mi">16</span><span class="p">,</span> <span class="n">id</span><span class="o">=</span><span class="ss">"181016"</span><span class="p">,</span> <span class="k">version</span><span class="o">=</span><span class="s1">'3.5.15.0'</span><span class="p">)</span> <span class="n">can1_mgr</span> <span class="o">=</span> <span class="n">can1</span><span class="p">.</span><span class="n">find</span><span class="p">(</span><span class="ss">"CANopen_Manager"</span><span class="p">,</span> <span class="k">False</span><span class="p">)[</span><span class="mi">0</span><span class="p">]</span> <span class="n">aoutId</span> <span class="o">=</span> <span class="n">device_repository</span><span class="p">.</span><span class="n">create_device_identification</span><span class="p">(</span><span class="mi">18</span><span class="p">,</span> <span class="s1">'55_AA030521'</span><span class="p">,</span> <span class="s1">'3.5.1.0'</span><span class="p">)</span> <span class="n">print</span><span class="p">(</span><span class="n">aoutId</span><span class="p">)</span> <span class="n">aout_dev</span> <span class="o">=</span> <span class="n">device_repository</span><span class="p">.</span><span class="n">get_device</span><span class="p">(</span><span class="n">aoutId</span><span class="p">)</span> <span class="n">can1_mgr</span><span class="p">.</span><span class="k">add</span><span class="p">(</span><span class="s1">'1AOUT'</span><span class="p">,</span> <span class="n">aoutId</span><span class="p">)</span> <span class="err">\</span><span class="o">#</span> <span class="n">can1_mgr</span><span class="p">.</span><span class="k">add</span><span class="p">(</span><span class="n">name</span><span class="o">=</span><span class="s1">'1AOUT'</span><span class="p">,</span><span class="k">type</span><span class="o">=</span><span class="mi">18</span><span class="p">,</span> <span class="n">id</span><span class="o">=</span><span class="s1">'55_AA030521'</span><span class="p">,</span> <span class="k">version</span><span class="o">=</span><span class="s1">'3.5.1.0'</span><span class="p">)</span> </pre></div> <p><img alt="IMG: 2019" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=4944"/></p> <p><img alt="IMG: 2019" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=4943"/></p></div>
