Siemens SIMATIC NET S7-300 User Manual

1 Communication via Ethernet CPs in S7 Stations
A-44
S7-CPs for Industrial Ethernet Configuring and Commissioning
Release 01/2007
C79000-G8976-C182-07
Organization in a Multiproject
If you use a multiproject organization, follow the steps below to connect the
S7-400/1 station to the PROFIBUS (1) subnet:
Create a subnet of the type PROFIBUS in both subprojects and merge these two
subnets in NetPro.
Representative Objects for Stations Outside the Current Project
If you do not want to use the multiproject functions, you can fall back on the use of
representative objects as used previously.
To be able to network the representative objects, you must once again create a
subnet of the type PROFIBUS in both projects as shown in the example here.
