Siemens SIMATIC NET S7-300 User Manual

1 Communication via Ethernet CPs in S7 Stations
A-42
S7-CPs for Industrial Ethernet Configuring and Commissioning
Release 01/2007
C79000-G8976-C182-07
Use this variant when you want to operate projects separately due to the
complexity.
Stations of the type SIMATIC S5 function in just the same way as
representative objects.
Merging Projects in the Multiproject:
If you have used the multiproject functions allowing you to use connections to a
partner in an unknown project, STEP 7 will automatically attempt to synchronize
two separately configured connections.
If you have configured projects with representative objects and want to merge
these projects into a multiproject, you have the following options:
 You can leave the representative objects with the configured connections
unchanged.
 You can reassign the connection partner and then delete the representative
objects.
