You can configure an OPC UA server to ensure it is connected and its status is regularly communicated.

Procedure

  1. In the navigator, click Proficy System > Proficy System > OPC UA.
  2. From the OPC UA Servers list, select the OPC UA server you want to configure.
  3. From the Displays panel, select HW/SW > OPC UA Editor.
    The OPC UA Editor appears.
  4. If applicable, select a new server URL:
    1. Click the ellipsis (…) next to the Server URL field.
      The OPC UA Server Details dialog box appears.
    2. Enter the URL of an OPC UA discovery server, and then click Discover.
    3. Select the new URL in the Server Name field.
      The Endpoints for the selected OPC UA server appear.
    4. Select an endpoint from the list, and then click OK.
      Alternatively, enter the desired OPC UA server URL directly.
      Tip: If a SignAndEncrypt endpoint is selected, the Use Security check box in the OPC UA Server Details dialog box is automatically checked.
  5. In the Authentication Settings, choose from the following:
    • Anonymous - used if the endpoint selected has no security and an anonymous login is allowed.
    • User/Password - used if the endpoint selected has security, or an anonymous login is not allowed.
    If User/Password is chosen, enter the User Name and Password for the selected server.
  6. Click Save, and then click Check Connection.
    The system displays a green Connected message.
    Note: If a red Disconnected message appears, check your authentication settings.
