<div class="markdown_content"><p>There is a setting that by default is turned off. It's called auto-reconnect - its in the setup page near the IP address I believe. I've had issues before where turning this on fixed things. This is only assuming the Arduino end is not messed up..</p> <p>I attached a screenshot of it..</p> <p><img alt="IMG: autoreconnect.jpg" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=1671"/></p></div>

<div class="markdown_content"><p>I'm using two arduinos as Modbus TCP slaves to my codesys/raspberry (using this tutorial as base <a class="" href="http://www.fleaplc.it/en/tutorials/33-arduino-as-raspberry-pi-s-remote-io-codesys" rel="nofollow">http://www.fleaplc.it/en/tutorials/33-a ... io-codesys</a>). Normally everything works fine but sometimes (can bee months between) the modbus communication is going down. As far as I can see (I'm no expert to codesys) it is the slaves that stops working. If I disconnect and then reconnect the power supply to the arduinos the communication starts working again. is there anybody that have experienced the same problem and found a solution?</p> <p>/Johan</p></div>
