<div class="markdown_content"><p>If you add data through the I/O area, the PDOs in your project result locked, whereas if you manually add indices into the Object Dictionary and then proceed to mapping onto your GVL, then they are editable. Though I do not know why.<br/> P.S.: the .project file is enough ;-)</p></div>

<div class="markdown_content"><p>sgronchi, could you elaborate on that some more? I did the following:<br/> 1. added the CANbus device<br/> 2. added CAN local device<br/> 3. edit I/O area, add area and then the variables <br/> 4. mapping to gvl variables</p> <p>That's all I did and the first ones I did aren't locked.... When you asked for the EDS file, I had to look it up.</p></div>

<div class="markdown_content"><p>I had not heard of a EDS file till yesterday so I didn't do anything with exporting or importing...</p></div>

<div class="markdown_content"><p>If I understand correctly, you are locked up now.<br/> I'd bet you did the following:<br/> 1) Created a CANopen local (slave) device in your Codesys project.<br/> 2) Did the mapping.<br/> 3) Exported its EDS.<br/> 4) Installed the EDS as a device into the Codesys device repository.<br/> 5) Added a CANopen Manager (master) in the tree.<br/> 6) Added the just installed device underneath the CANopen Manager.<br/> 7) Maybe deleted the local device (wrong thing)<br/> Just redo points 2, 3, 4, and 6 and you will be fine.</p></div>

<div class="markdown_content"><p>So how do I change it? Was my original question.</p></div>

<div class="markdown_content"><p>Well, you have imported an EDS to have PDO mappings locked.</p></div>
