5.2 Possible Connection Configurations
Communication connections are possible between the communication partners
shown in the diagram below.
The communication partners can be in the same project or distributed in the
subprojects of a multiproject.
Connections to communication partners outside a project are configured using the
STEP 7 object “Partner other project” or using substitute objects such as ”Other
stations” or SIMATIC S5.
