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:
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.
