<div class="markdown_content"><p>I have solved the problem.</p> <p>Appearently my XMC4500 was assigned the same MAC addresses. This caused the router to be confused which was which. Buy assigning uniq MAC-addresses for the cards solved everything and now it is running smothly.</p> <p>BR<br/> Mattias</p></div>

<div class="markdown_content"><p>HI again!</p> <p>I am trying to communicate to multiple XMC4500 infineon developmentcards through modbus/TCP where they act as slaves to my raspberry pi3.</p> <p>Currently I have succeded to establish communication to my soft PLC at my laptop and a XMC4500 at the same time. But when I am adding a second XMC4500 device it can not have connection to both at the same time. Instead it is alternating the connection with a random cyclic behavior where one card have connection at the time. </p> <p>I have assigned them with static IP at 192.168.0.201 and 192.168.0.202.</p> <p>Is there anyone that has faced a similar problem?</p> <p>BR<br/> Mattias</p> <p><img alt="IMG: codesys_forum.png" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=1998"/></p></div>
