    Disable security checks for OPC UA connector




      In our use case the machines (Schuette production grinders) which expose OPC UA interface do NOT provide any server certificates thus not requiring any secure connection.

      However, I don't see how to disable security checks and make it work with OPC UA connector. I could not find any relevant setting.

      The error it returns is the following:


      Severity: Error

      Timestamp: 07/10/2018 18:33:59.412

      Message: [X03] Connection failed. Please verify that the connector trusts the certificate provided by the server. Error: BadSecurityChecksFailed Message: Security was requested but the server does not have any secure endpoints.


      As per OPC UA standard it is perfectly viable scenario to work without security enforced by client/server certificates. So, how can I disable security on OPC UA connector?

      We have same machines working with Unified Automation UaExpert and our custom OPC UA app perfectly fine.


      Thanks in advance.
