Certificate of the OPC UA server
When you have activated the OPC UA server and have confirmed the security prompts,
STEP 7 automatically generates the certificate for the server and saves it in the local
certificate directory of the CPU. You can view and manage this directory with the local
certificate manager of the CPU (exporting or deleting certificates).
The figure below shows the local certificate manager of the CPU with the automatically
generated certificate for the OPC UA server:

Alternatively, you can also generate a server certificate yourself.
The certificate of the server is transferred from the server to the client during establishment
of a connection. The client checks the certificate.
