<div class="markdown_content"><p>Hello there,<br/> today i'm having problem about the communication between HMI (Weintek, protocol CODESYS V3 Ethernet) and Raspberry pi<br/> At the power up everything is fine and communication work properly, then when I perform a download of the panel project it seems like the port (or the protocol) remains busy and the communication does not work. if I stop and restart runtime on Raspberry the communication doesn't restore. If I delete application on RasPi and download again communication doesn't restore. The only way to restore communication is to switch off and on again. </p> <p>Does anybody know how to manage the connection resouces of Raspberry Pi??<br/> Does anybody know how to debug this problem?</p> <p>The version of the runtime I'm using is 4.0.0.0</p></div>
