<div class="markdown_content"><p>Hi,<br/> the only thing is you need to do:<br/> Map variables and use them in the pou's!</p> <p>Independent which fieldbus you are using, this is mandatory to have an update cycle (unused variables are never updated due performance reason - not needed to update when they are not used)<br/> If you just want to test by setting variables manually/force them you need to change to 'Enable 2 always in buscycle Task - see screenshot.<br/> You see if the IO's are updated - if they are the variables are <strong>blue</strong>/<strong>black</strong> when you are online - if not updated light gray</p> <p>BR<br/> Edwin</p> <p><img alt="IMG: alwaysUpdate.jpg" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=2884"/></p></div>

<div class="markdown_content"><p>Hi,</p> <p>I connected an RPI3 running Codesys Control (current version) to the Ethernet port of a UR10 (Robot) in order to establish a Profinet fieldbus connection. While the Bus seems to be running (green status in Codesys and on the UR10), all the entries in the I/O mapping are greyed and have no live values. I am rather new to CodeSys, so I hope it is just a stupid mistake on my side? As you can see I have not implemented anything like POU, mappings, variable lists and so on yet - is this maybe necessary?</p> <p>A second question concerns the actual naming of each byte/word/bool in Codesys. UR provides two .awl files (for input and output) as well as a UDT file. Can I use those in Codesys as well? Currently each I/O is listed as byte and unnamed.</p> <p>Hope you can point me in the right direction!</p> <p><img alt="IMG: Unbenannt3.png" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=2876"/></p></div>
