To allow applications to exchange information over configured communication
connections, the project engineering data created with NCM PC / STEP 7 must be
loaded on the PC station.

If the initial configuration was performed with XDB import of the project engineering
data, loading is already completed with the initial configuration.

Refer to the explanations relating to initial configuration in Section 2.2 Steps for
Initial Configuration.

The section below describes how project engineering data can be downloaded to
the PC station after the initial configuration. This is necessary when the project
engineering data is not yet available at the time of the initial configuration, or to
make changes to the project engineering data.

There are three possible ways of transferring a configuration from the project
engineering to the PC station

S

Online mode

-

networked (engineering station networked with runtime PC)

-

locally (project engineering station and PC station one and the same)

S

Offline mode (engineering station and runtime PC separate)  -  XDB import

Downloading as described below only results in successful installation of the
communications services on your PC station if the arrangement of the
components in the configuration data is identical with that of the configuration data
on the PC station.
