<div class="markdown_content"><p>I don't work for IFM, nor for CODESYS and didn't create the .eds file or developed the CAN protocol. I have no knowledge of the exact contents and SDO's or PDO's which are exchanged. So no, I am not sure. But if the .eds file confirms to the CANopen specifications, why shouldn't it?</p></div>

<div class="markdown_content"><p>Thanks,You sure there are not compatibility issues with the old IFM EDS files, PDO mapping, or startup SDO configuration in CODESYS 3.5?</p></div>

<div class="markdown_content"><p>Yes, you can use the .eds files also in CODESYS 3. Install them through the menu Tools - Device Repository. Then you can add the CANopen devices to your CANopen manager in your device configuration.</p></div>

<div class="markdown_content"><p>Hi,</p> <p>I am migrating an existing IFM system from CR0020 + CODESYS 2.3 to CR710S + CODESYS 3.5.</p> <p>The existing CANopen I/O modules are:</p> <p>CR9011<br/> CR2042<br/> CR2011</p> <p>My questions are:</p> <p>Can these legacy IFM CANopen modules be used as slaves with the CR710S CANopen Master?<br/> Can their existing EDS files be imported directly into CODESYS 3.5?<br/> Are there any known compatibility issues with the old IFM EDS files, PDO mapping, or startup SDO configuration?<br/> Has anyone successfully used these modules with a CR710S? If so, could you share the recommended configuration procedure?</p> <p>The goal is to replace the CR0020 with a CR710S while keeping the existing CANopen I/O modules</p></div>
