Change to the archive structure, manual data transfer

9.4.1

General information

The automatic metadata synchronization described above does not always result in obtaining
the available runtime data. The engineering tool generates a corresponding warning in these
cases.
In some cases, changes to existing user archives may affect the structure of the corresponding
runtime archive, the content of the corresponding configuration archive and the interface of
the relevant AS function block. Changes which may have this effect include adding
parameters / attributes. No automatic process is currently available to deal with this. The
following steps must therefore be performed manually.
Note
To avoid this type of change, it is advisable to create a number of invisible reserve parameters /
attributes in advance which can then be made visible and used where necessary. This avoids
the need for a complete AS download and prevents a structure change in the runtime archive.
The examples below are based on a parameter being added to parameter set group 1. Archives
FB_PARAM_001 and FB_PARAMATTRIB_001 are affected accordingly. The following table
shows the relationships for all other archives:
Module

ment
Material lot man‐
agement
Storage location
management

agement
Archive manage‐
ment
xxx represents the respective material class / parameter set group / archiving group to which
changes are being made. In the special case of storage location management, the
configuration archive for attribute changes is FB_STORATTRIB and the configuration archive
for value changes FB_STORVALUE.
To perform such a change without loss of process data, the following procedure should be
followed. A distinction is made between a single-user station and server/client architecture.
