<div class="markdown_content"><p>"CANopen Manager -&gt; General -&gt; NMT error behavior" is perhaps set to "Stop Slave"?<br/> Shame that there isn't a "Do nothing" option...</p></div>

<div class="markdown_content"><p>I have a Codesys compatible PLC with several CANopen sensors. Three of them periodically goes in heartbeat timeout, but I found from logging the canbus, that it is caused by the CANopen master sending NMT reset (0000 2 81 xx) messages to one of the sensors peridically. The CANopen library contains implicit functions blocks that are called by the configuration, so I have difficulty determining why it happens. I have added the CAN_DEBUG in compile define, but that did not yield any valuable information regarding this issue. Can anyone provide more debugging information? Thank you</p></div>
