9.9 Report creation and archiving of batch data
this data was transferred by the PCS 7 OS to the PH over the entire duration of the batch (in
other words, also during the time prior to the changeover to the "PH" archiving method).
Note
Recommendation
To make sure that the batch data is complete both in the PH archive and in the batch report,
before changing to the "PH" archiving method, all batches should have the status "completed
+ closed + archived".
In the project settings, the "Archive automatically" setting should be disabled so that the
archiving of completed batches is not suddenly activated during the changeover. Implementing
this recommendation is the responsibility of the user and is not checked by the system. If the
recommendation is not followed, the restrictions listed above apply.
Failure of the PH
If the connection is disrupted or if the PH fails, it is no longer possible to create batch reports
on the SIMATIC BATCH clients or on the Information Server. If the connection between a
SIMATIC BATCH client and the IS is disrupted, the restriction only applies to this SIMATIC
BATCH client. If, on the other hand, the connection between the SIMATIC BATCH server and
PH PC or the PH PC itself is faulty, no more data will be archived.
If a PH fails, an OS message is always generated and displayed.
Note
The duration of the subsequent data synchronization depends on the length of time of the
failure and the performance of the PC. Depending on these factors, it will take a corresponding
time before current batch data is again available "promptly" in the PH archive.
Viewer for archived batches
Archives (XML, PH, CAS) of older SIMATIC BATCH versions cannot be displayed with the
viewer for archived batches in SIMATIC BATCH V8.1 SP1 or higher. To display such archives
with the viewer, the viewer of the relevant previous SIMATIC BATCH version is used.
