<div class="markdown_content"><p>Hi,</p> <p>I noticed that the jitter of the fieldbus task increases a lot when re-starting the EtherCat Master. Simultaneously, the CPU load increases considerably on the RTE side. </p> <p>After restarting, jitter remains stable (within +/-50 us) and CPU load also decreases to a stable value. Is this normal/expected? Are CPU load and jitter somehow intertwined?</p> <p>The target device is a Beckhoff CX5120 running WES7-32bit and CODESYS RTE.</p> <p>Thank you in advance,<br/> Omar</p></div>
