Import a CA-signed certificate and assign it to the client

To assign a CA-signed certificate to the server, you must send a certificate signing request to a third-party certificate authority. After receiving the signed-certificate from the CA, import it to the server. The DeltaV\DVData\Import-Export folder is the default folder for importing certificates.

  1. Select the OPC UA Client in the DeltaV Explorer hierarchy.
  2. Right-click Properties.
  3. Click the Certificate tab.
  4. Click Import.
    The software displays the Open dialog.
  5. Select the .pfx certificate files or browse to the correct location.
    The software assigns the certificates to the client. Trusted certificates are in .cer or .der format.
