OPC UA without certificate

Hi,

is it possible to get data from the AXC F 2152 over OPC UA without using the certificate.

The client I want to use only supports authorization with user and password.

Best regards

Christoph

  • The OPC UA certificates are used for endpoint encryption.

    With the current version of the OPC UA Server in PLCnext Control devices, it is not possible to authenticate OPC UA users using certificates. The only possibility to authenticate a user is with a username and password.

    If your OPC UA client does not support endpoint encryption, then it is possible to disable endpoint encryption in the OPC UA server, but in that case user authentication will also be disabled.

  • Hi Martin,

    thank you. This is good news

  • Hi Martin,

    where can I disable endpoint encryption in the OPC UA server?

    Best regards

  • If you disable User Authentication using Web-Based Management, then you can connect to the OPC UA Server using "None" for the security settings (this doesn't use endpoint encryption), and with no Username or Password.

    This is a working UaExpert client configuration using the AXC F 1152 simulation:


  • Does not work.

    Do I need to reboot?

  • I don't understand, sorry. What behaviour are you seeing?
