<div class="markdown_content"><p>Dear All,</p> <p>I am using Codesys on RPi.</p> <p>I have tried to reach variables via OPC UA. As far as I know, in that case, I have to check the item in the Symbol Configuration. I made it.<br/> After that, I use Node-red to display the data on a web page. During the test it worked well, but nowadays the new clients can not connect to the Codesys. Even I restart the Pi, runtime, Node-red, it does not connect.<br/> The logic runs, variables change, but the client can not connect.<br/> Originally there were some clients, but due to the connection problems I have deleted them, and I have only 1 now.<br/> But it can not connect at all.<br/> Is there any log or limitation in Codesys which does not allow new clients? If yes, how can I delete them?<br/> If no, how can I find the cause?</p> <p>Thank You in advance!</p></div>
