Release Notes for SP02

Support for Certificate Rotation in the OPC UA Source System (New)

As of Release 15.5 (support package 02), you can specify on the Security tab in the OPC UA source system that you want the certificates that are configured for authentication - the application certificate and session certificate - to be identified at runtime by their respective subject. At runtime, the appropriate certificate is then selected from the list of certificates in the selected storage location according to the subject defined in the configuration. If there are multiple certificates with this subject, the certificate with the latest valid-to date is used.

With this setting, the system supports certificate rotation. You can renew the certificate during productive operation, provided it has the same subject as the configured certificate. You don’t need to adjust the certificate configuration in PCo after exchanging the certificate.

This function is also provided for OPC UA source systems that you have created using the Machine Model in the SAP Digital Manufacturing Cloud.

Support for Certificate Rotation for OPC UA Servers (New)

As of Release 15.5 (support package 02), you can specify on the Security Configuration tab for the OPC UA server that you want the application certificate that is configured for authentication to be identified at runtime by its subject. As with the OPC UA source system mentioned above, this supports certificate rotation.

This function is also provided for OPC UA servers that you have created using the Machine Model in the SAP Digital Manufacturing Cloud.

Triggering Subscription Items for Versioned Notifications (New)

For Release 15.5 (support package 02), the functions for triggering subscription items have been added to the versioned notifications. Until now, these were only available for static notifications. This enables you to control the conditions under which a subscription item triggers a notification message when values are changed. The following options are available:

  • Only subscription items used in trigger condition

  • Subscription items used in trigger condition or output expressions

  • All subscription items

These functions are also provided for versioned notifications that you have created using the Machine Model in the SAP Digital Manufacturing Cloud.

ODBC Destination System: Raise Exception if Errors Occur (New)

The checkbox Raise Exception on Write or Connection Errors has been added to the Configuration tab. If you select the checkbox, the ODBC destination system generates an exception if an error occurs when writing to the database.

The generated exception can then be used in the following ways:

  • If you have assigned the ODBC destination system directly to a notification, the exception can trigger the redelivery of the notification message.

  • If you call the ODBC destination system from a multiple call destination system, you can select the Exception Handling checkbox in the corresponding step of the multiple call destination system. This enables you to react in a controlled manner to the occurrence of a database write error in your multiple call destination system.
