Batch data archiving and logging in XML format
The batch data which are only accessible to authorized persons
or systems are saved in XML format. The Batch Report
function provides an XML-based batch report as standard
which can be displayed and printed by means of BatchCC or
the protocol viewer. In addition, the XML data can also be processed
further by an external report system.
Library with recipe operations (ROP)
The management of recipe operations is conveniently supported
by a user library (ROP library). Library recipe operations
can be inserted as a reference in recipe procedures and can
thus be modified from a central location. This reduces the requirements
for engineering and validation. If the reference
link is broken, the recipe operation becomes a fixed component
of the recipe procedure, and is thus independent of further
central modifications.

Validation according to 21 CFR Part 11
The number of plants which have to be validated for observance
of quality standards because of marketing and statutory
requirements is permanently increasing. The process control
system and its manufacturer play an important role in the validation
procedure.
SIMATIC BATCH particularly supports validation according to
21 CFR Part 11 through:
■ Consistent standardization, e.g. with type/instance concept
of the SFC, recipe creation independent of plant unit,
isolation from procedure and formula, library recipe operations
■ Audit trail (modification logbook):
- Recording of changes in recipes and recipe operations
(saved with modified object)
- Recording of changes during production (in the batch
report), including the
- operations at the individual control level belonging to
the corresponding batch
■ Version assignment (lifecycle of recipes, recipe operations,
formulae)
■ Central user administration with access control through
SIMATIC Logon
■ Electronic signature for release of master recipes, formulae
and library objects based on SIMATIC Logon
Furthermore, Siemens as a manufacturer of process control
systems has specially trained personnel as well as many years
of experience in quality management and plant validation.

MIS/MES interfacing
Interfacing of MIS/MES systems is supported by:
■ Integration of SIMATIC PCS 7 into SIMATIC IT
■ An open interface (API) for customized expansions.
Separation of procedure and formula
Separation of procedure and formula
The flexibility achieved by recipes which are independent of
plant units can be increased even further if the procedure and
parameter sets (formulae) are separated from one another.
Various master recipes can be created by linking several formulae
using a recipe procedure. This enables central modification
of procedures. The formula structure is determined by
the formula category defined by the user.
