Communication via Ethernet CPs in S7 Stations
to bring connections with identical connection names together.
The topic of multiprojects is dealt with in detail in the STEP 7 basic help. Here, you will find information on the following topics:
S Requirements for interproject functions
SHow to create multiprojects
SHow to create a new project in a multiproject
SHow to separate a project from a multiproject
SHow to include projects in the multiproject
SHow to synchronize projects in a multiproject
SMoving stations within a multiproject (when a station is moved from one project of a multiproject to another project of the same multiproject (for example using drag & drop), the interproject connections are retained).
SPossible problems in distributed projects and tips on how to avoid them
Possibilities for stations outside the current project
The addition of the multiproject functionality means that the following situations can arise:
SConnection to a partner in an unknown project
The new multiproject functionality allows you to create a connection to a partner in an unknown project. In this case, you can specify a connection name as a reference in the properties dialog of the connection. When the projects are merged, STEP 7 then supports you with automatic synchronization of the separately configured connections.
The connection remains unspecified until the projects have been merged and the connections synchronized. Only following this synchronization can the configuration data be downloaded to the local station without inconsistencies.
You should therefore use this variant when you know that the projects will be merged in a multiproject.
SSpecified connections with representative objects
To allow you to create specified connections to stations in a different project (for example production 2) or that are not managed with STEP 7, you can configure these stations as other stations(example in the project production 1).
This makes it possible to create consistent, fully specified configuration data and to download it to the local station.
It is also possible to create specified connections between these stations in different, independent projects. The stations can then communicate immediately over the created connections after the configuration data have been downloaded.
Use this variant when you want to operate projects separately due to the complexity.
