<div class="markdown_content"><p>Hi everybody (sorry to post here in english, unfortunatly, I don't speak german)</p> <p>I'm tring to use Codesys v3 with a CoE device.</p> <p>And with the library ETC_CO_SdoWrite, I want to send some SDOs.</p> <p>The objects with size lower than 5 bytes work's perfectly but with the others (more than 4), I get an error. In fact, I don't know why, CoDeSys is supposed to send a segmented object, the first SDO is correct, he send an "initiate download protocol" and then after he should send a "segmented" one but he send again the same "initiate download protocol" </p> <p>What I made wrong ?</p> <p>thank you in advance</p> <p>in the following, my function ETC_CO_SdoWrite and a capture of what is sent (using codesys v3.3 patch1) :</p> <p><img alt="IMG: Bild" rel="nofollow" src="http://img84.imageshack.us/img84/4407/sanstitreiz.jpg"/></p></div>
