Post by cihangur on OpC UA server on Raspberry Pi 64 SL runtime ^{CODESYS Forge talk (Post)}
Hello everyone, I wanted to write here because it is a similar and the most up-to-date topic. I want to connect to CoDeSys Win V3 x64 - 3.5.19.50 with OPC UA using WinCC Advanced V17. (Or to a PLC with CoDeSys Version 4.10.0.0) My settings are exactly the same as the previous comment. I even tried many different settings. I can access all CoDeSys OPC UA variables via TIA Portal IDE and add them to my HMI tags. When WinCC RT Advanced is started, it gives a warning that the connection could not be established and does not update the variables. I can connect to Inovance AM600 using CoDeSys Target version 3.5.11.50. (The same version Win x64 is also connected.) However, a security setting in the current versions prevents me. I would be very happy if those who have up-to-date experience on this issue and find a solution share it. The CoDeSys Security Settings which I can access variables with TIA Portal: CommunicationPolicy: POLICY_BASICSHA256SHA256 CommunicationMode: ALL Activation: Activated UserAuthentication: ENABLED Server Certificate: Valid until 2034 Greetings.

Post by mohammedben on Fail communication between CODESYS and Fuxa SCADA via OPC UA ^{CODESYS Forge talk (Post)}
hi, When I try to establish communication between CODESYS and Fuxa SCADA via OPC UA, the connection fails, and I receive the following error: 2026-02-15T08:38:13.618Z [ERR] 'codesys' connect failure! Error: The connection may have been rejected by server, Err = (ClientTCP_transport6: socket has been disconnected by third party) 2026-02-15T08:38:13.619Z [ERR] 'codesys' try to connect error! Error: The connection may have been rejected by server, Err = (ClientTCP_transport6: socket has been disconnected by third party) 2026-02-15T08:38:13.622Z [ERR] 'codesys' connect error! undefined (1) Note that there are no problems when I establish communication with the UaExpert and OPC UA Client Simulator software. I also previously tried communicating with RapidSCADA and received the following error: Endpoint with the specified security options not found. And when I try to connect with "none" in the security policy, I get this error: BadSecureChannelClosed I have tried almost all the solutions available online and have not found a solution. I hope you can provide me with a solution that solves this problem. Thanks in advance

Post by rossanoparis on How to configure CODESYSControl_User.cfg in order to use a specific network card for OPCUA Server ^{CODESYS Forge talk (Post)}
Hello at all I'd like to know how to configure CODESYSControl_User.cfg in order to use a specific network card for OPCUA Server. In the past, I tried to ask in "Forge" about this topic, but I could find neither help nor document informations about it. Reading the file "codesyscontrol.log" I see these logs OPC UA Server Started: Hostname: NTLRPICTRL01, Port: 4840 URL: opc.tcp://NTLRPICTRL01:4840 Loopbackadapter activated. **All available networkadapters are used.** Multithreading activated. 3 workers used. My controller, which is a Linux PC, has got two network cards eth0 and eth1 I whant to use the card with name "eth0" as a server for OPCUA and keep the "eth1" free for other stuffs. Is it possible ? Best regards Rossano
