Post by arundara on OPC UA Server Stops after 5 consecutive disconnections of ethernet port ^{CODESYS Forge talk (Post)}
Hello Every one, During testing of OPC UA communication between UA Expert software and the CODESYS SoftPLC on a Linux environment, an observation was made. When the Ethernet cable was disconnected and reconnected with 2-minute intervals, on the 5th attempt, the OPC UA connection failed to establish in UA Expert software. At this juncture, restarting the CODESYS SoftPLC enabled the reestablishment of OPC UA communication. The same result was obtained when testing on a Raspberry Pi SoftPLC. What is the reason behind this phenomenon? and whether there are settings to stop this behavior? Please help. Thanks & Regards.

Post by esave on OPC UA Server with on Codesys + OPC UA Client on Labview ^{CODESYS Forge talk (Post)}
Hello everyone I want a communication between my PLC as an OPC UA Server and Labview on my PC as the OPC UA Client. I have an Festo CPX-E-CEC-C1-PN PLC and I have the OPC UA Toolkit from Labview. I created some Variables for testing (see picture 1) on Codesys. I tried to use this Labview block diagram (see picture 2) but I cant connect the PLC to it. What do I have to type in the Server Endpoint URL and what in the Node ID? Is this a good way for communication with a PLC to a PC? If not is there another way?

Thank you for your answer! I'm not sure, but it seems this is not what I am looking for. I attached three pictures. The first one is from the Codesys IDE. I use an Information Model to generate an OPC-UA server. I connected via UA-Expert, and there I see the URIs I would like to change.
