Hello,

Is it possibe to establish a communication between an OPC UA client and the OPC UA server that PLCnext has, where the credentials are not required? (I mean, that the client has not to introduce user and password to be connected to the server).

Could you show what I need to configure or point me to the right documentation?

Thanks

Hello Javir,

you can dissable Security and Authentication for the PLC and the option of annonymouse Auth will be activated.
You could also try using certificate authentication instead if "No Auth" is not an option because of security reasons.
