Archive management

8.1

Overview

The "Archive management" APF module is used to implement automation tasks such as the
following:
● Creating and updating of archiving data records
● One-time export and configurable deletion of archive data records for external post-
processing
User archives
You can find information on the archive management user archives in the "Archive
management" tab of the "Settings" dialog.
OS process pictures
The archive management is configured on the AS and controlled on the OS using WinCC
scripts. No picture objects are needed for this module. Execution of the archive functions is
triggered via the interconnected APF modules.
AS function blocks
To generate the function blocks for the archive management, the APF engineering tool uses
the "FB_XXXA" function block (FB1793) as a template and generates the following function
blocks for each created archive group:
FB_XXXAI
FB_XXXAR
