Multi-project engineering
Multi-project engineering permits division of a large complex 

project into several subprojects in accordance with technologi-

cal criteria in order to allow several teams to work on the project 

in parallel. To achieve this, a host "Multi-project" is defined in the 

SIMATIC Manager. Individual (sub)projects can be inserted into 

or removed from a multi-project at any time. Similarly, projects 

can be divided or combined (Branch & Merge).
Central configuration functions for multi-projects help to reduce 

the configuration overhead. For example, a hierarchy folder can 

be created in the current project and also automatically in all 

other projects. It cannot be modified there, but objects can be 

inserted. All block types used in a multi-project can also be up-

dated centrally.
The (sub)projects belonging to a multi-project are saved on a 

central server and can be sent to local engineering stations for 

editing. The engineering performance is then not affected by 

network access.
Concurrent engineering
In the case of concurrent engineering, several configuration en-

gineers can work in CFC and SFC simultaneously on a project 

without this having to be first divided into subprojects. The 

project is located on one of the engineering stations involved. 

This requires connections to the OS LAN (terminal bus) and 

plant bus in order to download the configuration data to the tar-

get systems. 
The engineering stations working as "project clients" can access 

the project data via the OS LAN (terminal bus) or a different 

LAN/WAN. A CFC can be opened and viewed simultaneously by 

several configuration engineers. However, simultaneous write 

operations to the database are rejected by the system.
It is then possible, for example, to use charts in online (debug-

ging) mode during commissioning while carrying out modifica-

tions to the project at the same time.
Branch & Merge
Branch & Merge supports the division and combination of 

projects from the technological viewpoint.
Charts or plant units can be copied into another project and ed-

ited there. Interconnections which are not specific to a project, 

typically for interlocking, become text interconnections. When 

merging, charts with the same name are overwritten in the origi-

nal object, and text interconnections – even those which you 

have entered yourself – can be closed by pressing a button.

Project views 
The SIMATIC Manager supports the various tasks for creating a 

plant project by means of the following project views:
• Component view (HW-Config)

for configuration of hardware such as automation systems, 

bus components or process I/O

Component view: hardware configuration in the SIMATIC Manager with 

HW-Config

• Process object view 

as the central development environment for all aspects of pro-

cess tags/objects

The process object view of the SIMATIC Manager supports the 

work of a process engineer by providing a universal view of the 

process tag. It shows the technological hierarchy of the plant 

(presented in tree form) in combination with a tabular view of all 

aspects of the process tag/object (general data, parameters, 

signals, messages, image objects and measured value ar-

chives). This provides the technologist with fast orientation.
All objects in the marked branch of the hierarchy are displayed 

in the table so that they can be directly processed with user-

friendly edit, filter, replace, import and export functions. A spe-

cial test mode offers the facility for testing process tags and 

CFCs online and for starting them up.
