OPC UA security

Set up Certificate Logon for a DeltaV OPC UA PK controller server with third-party clients

Note

Connecting to third-party clients that are external to the DeltaV network is a security risk.

Note

User Certificate logon requires that application certificates are trusted.

  1. In DeltaV Explorer, navigate to the PK controller's OPC UA server subsystem and right-click Properties.
  2. Select the Certificate Logon checkbox.
  3. Click View Certificate.
    The software displays the View User Certificate dialog. Make sure there are values in the Name, Valid Until and Thumbprint fields. If these fields are blank, click Generate. Then, click Close. Click OK. Download the OPC UA server.
  4. Enter the password and click Export.
    The software exports a .pfx file. Third-party clients need this file for certificate Logon.
  5. Enter a password. This password will be used later when splitting the certificate into .der and .pem files or when importing the .pfx file.
