<div class="markdown_content"><p>Thank you, for the reply.</p> <p>The CANopen slave is communicating with the CoDeSys CANopen master successfully.<br/> I'll investigate the configuration. And try to isolate the issue.</p> <p>Regards,<br/> Edwin.</p></div>

<div class="markdown_content"><p>Hi Edwin,</p> <p>Some weeks ago I was at a customer who had the same message when using the RECV_EMCY function block.<br/> If I can remember correctly it was related to the fact that the device was either not configured correctly in the device configuration, or the communication was not working correctly yet.<br/> Is your CAN node communicating correctly with the CODESYS controller?</p></div>
