	Standard engineering software
	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
4	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.

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

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.

•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.
