Specifying connection paths

Rules for connection configuration
Note the following rules for connection configuration:
● Connections can be configured for the following networks:
– Connections in Ethernet networks between TIM modules and CPs
– Connections in classic WAN networks (dedicated line/dialup network) - only between
● You can create connections between endpoints (subscribers) that are configured in the
STEP 7 project.
Fields are available in the connection table for the address data and interface parameters
of both endpoints.
● The endpoint of a connection is always the CPU, not the communications module.
Exception: Third-party device (see below)
● A connection segment must be created for the way there and the way back for each
connection.
Example of a connection between Partner 1 and 2:
– Connection segment 1 ⇒ 2
– Connection segment 2 ⇒ 1
● A connection must run over a single subnet.
● You can create connections between an endpoint of the STEP 7 project and a "third-party
device" that is not configured in STEP 7. The third-party device is located in another
subnet and can be reached via a network gateway.
In this case, configure the network gateway as an endpoint of the connection.
● You can configure single and redundant connections between two subscribers.
