8.5 Distributed multiproject engineering

Updating process cell data
Note
If you modify the basic control (CFC/SFC charts, hardware configuration, plant hierarchy etc.),
the process cell data must be compiled again, batch-relevant data must be transferred to the
operator stations and downloaded to the CPU (DB server, BATCH server, BATCH clients).
Before data is transferred to the operator stations, the OS must be recompiled.

Overview and important initial considerations

Introduction
In this section, we explain distributed multiproject engineering with SIMATIC BATCH. This
involves the exchange of projects between central and several distributed multiprojects. These
projects can only contain SIMATIC AS stations.
These projects are exchanged by removing them from a central multiproject, inserting them
into a distributed multiproject, editing them in the distributed multiproject, removing them from
the distributed multiproject and finally inserting them back into the central multiproject.
Since BATCH multiproject configuration was only designed for editing within the context of a
single multiproject, a few important rules and restrictions must be taken into consideration for
distributed multiproject engineering with SIMATIC BATCH. These rules are described in this
section.
Central multiproject engineering: Scope
In contrast to distributed multiproject engineering, central multiproject engineering is used for
centralized tasks. Central multiproject engineering is, therefore, not a topic in this
documentation.
Note
The procedure for multiproject engineering is described in the document "PCS 7 V6.1+SP1
Configuration Guide for Multiproject Engineering" with the article ID 22258951 (http://
support.automation.siemens.com/WW/view/en/22258951).
