Configuring Connections
12.13.2 Basic Procedure for Configuring Connections between Projects
Configuring Connections with Multiproject
AS of STEP 7 V5.2 you can easily create interproject connections with the help of
the multiproject (see also the section: What you Should Know About Multiprojects).
Possible Connection Partners in the Other Project (without Multiproject)
There are two methods of setting up connections to connection partners in other
STEP 7 projects (without multiproject):
• Set up a connection to an "other station," a "PG/PC," or a "SIMATIC S5 station"
• Set up a connection to an "unspecified" connection partner
Note:
Connections to "other stations," "SIMATIC S5 stations," "PG/PC," and
"unspecified" connection partners are also possible within a STEP 7 project. To
which of these connection partners connections can be set up depends, among
other things, on the connection type.
Differences Between the Two Methods
• You must configure an "other station", a "PG/PC", or a "SIMATIC S5 station" as
subnet nodes in the current STEP 7 project. Restriction: For "other stations"
and SIMATIC S5 stations you cannot configure S7 connections. All other
connection types are possible.
• No subnet node needs to be configured in the current STEP 7 project for an
unspecified partner. You can set up S7 connections, PTP connections, ISO
Transport connections, and ISO-on-TCP connections to unspecified connection
partners.
Special Case for PtP Connections
In contrast to the case for STEP 7 connections, the configuration of PtP
connections to an unspecified partner does not require networking of the local
node. You only have to network the communication partners in an actual plant
before you place the connection in operation.
