Configure communication connections
The project engineering of connections i.e. the "link-up" between stations
happens in NetPro from Siemens. NetPro is a graphical user interface for
the link-up of stations.
A communication connection enables the program controlled communi-
cation between two participants at the Industrial Ethernet. The communi-
cation partners may here be part of the same project or - at multi projects -
separated within related part projects.
Communication connections to partners outside of a project are configured
via the object "In unknown project" or via deputy objects like "Other
stations" or Siemens "SIMATIC S5 Station".
By means of the handling block like FB 55 - IP_CONFIG there is the
possibility to establish program controlled communication connections.
More may be found in the manual "Operation list" of the CPU.
The following properties are characterizing a communication connection:
• One station always executes an active connection establishment.
• Bi-directional data transfer (Send and receive on one connection)
• Both participant have equal rights, i.e. every participant may initialize the
send res. receive process event controlled.
• Except of the UDP connection, at a communication connection the
address of the communication partner is set via the project engineering.
Here the establishment of a connection is always actively be
accomplished by one station.

• Siemens SIMATIC manager V. 5.1 or higher and SIMATIC NET is
installed.
• The CP has been engineered at the hardware configuration, entered
into the hardware configuration and linked-up to the Ethernet subnet.
• The CP as bus participant has an IP address respectively a MAC
address for ISO transport connections.
