8.9 Configure Siemens S7 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 communication between two
participants at the Industrial Ethernet. The communication partners may here be part of
the same project or - at multi projects - separated within related part projects. Communi-
cation 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 Sta-
tion". The communication is controlled by the user program with Yaskawa handling
blocks. To use this blocks, configured communication connections are always necessary
in the active station.

‘Siemens S7 connection - Communication functions’ page 114
The following properties are characterizing a communication connection:
n
One station always executes an active connection establishment.
n
Bi-directional data transfer (Send and receive on one connection)
n
Both participant have equal rights, i.e. every participant may initialize the send res.
receive process event controlled.
n
Except of the UDP connection, at a communication connection the address of the
communication partner is set via the project engineering. Here the connection is
active established by one station.
n
Siemens SIMATIC Manager V 5.5 SP2 or higher and SIMATIC NET are installed.
n
With the hardware configuration the CP was assigned with IP address data by the
properties of PN-IO.
Every station outside of the recent project must be configured as replace-
ment objects like e.g. Siemens "SIMATIC S5" or "other station" or with the
object "In unknown project". When creating a connection you may also
choose the partner type "unspecified" and set the required remote param-
eter directly in the connection dialog.
