<div class="markdown_content"><p>Hi,</p> <p>I am currently working on <strong>acyclic </strong>Profinet communication on the Raspberry Pi. My Profinet Device is a Hilscher netHat - The cyclic communication works pretty much out of the box, but when it comes to acyclic communication I get lost...</p> <p>To perform the acyclic reading of a Record I use the <strong>RDREC</strong> functionblock. Unfortunately the documentation for RDREC only describes the properties, but doesn't say anything about how it's supposed to be used properly. I am quite new to CoDeSys, therefore I would appreciate just a few examples to see how it's done by the Pros.</p> <p>Thank you!</p></div>
