<div class="markdown_content"><p>Hi,<br/> do you have applied a rt_preemt patch on your Rasbian?<br/> Seems that distributed clocks is enabled on any slave in your network. ( If you need this - rt_preempt is needed probably)</p> <p>If not a workaround might be ( depends on your application needs) to enable restart slave in the ethercat master (brings the slaves up back operational)</p> <p>Anyway you need to check the jitter in the taskmonitor on the ethercatmaster Task and the plc logger if it occure.<br/> In your case it Shows a changed Network amount slave..?!</p> <p>BR<br/> Edwin</p> <p><img alt="IMG: RestartSlave.png" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=3913"/></p></div>
