The data connection between an OPC UA Client and the WPM Gateway is generally established
via a secure connection. Therefore, the certificate of the OPC UA Client that will be connected
to the WPM Gateway must be uploaded to the WPM Gateway.
Upload OPC UA Client certificates to the Gateway
To obtain the OPC UA Client certificate, see the documentation for the OPC UA Client.
1) The certificate must be in DER format.
2) Drag and drop the DER file of the certificate into the upload area.

Alternatively, clicking in the upload area opens a file selection dialogue.
3) The certificate is automatically imported into the WPM Gateway.
