A-43
S7-CPs for Industrial Ethernet Configuring and Commissioning
Release 01/2007
C79000-G8976-C182-07
1.7.5 Network/Project Variant: Several Subnets in Several (Sub)
Projects
Configuration of the System
If several network types need to be used and if these need to be managed in
different projects due to the different tasks of the stations or due to the large span
of the plant, stations can be created as follows:
 Using (sub) projects in the “multiproject”
 by configuring “Other stations / SIMATIC S5” in the other project.
S7 - 300/1
S7 - 300/2
S7 - 400/1
Cell level = (sub)project 1
Cell level = (sub)project 2
