6 Using the CP 443 − 1 Advanced for
PROFINET IO
PROFINET IO allows direct access to PROFINET IO devices over Ind. Ethernet.
To access the field devices connected to PROFIBUS DP, there are gateways
available that are used as PROFINET IO proxies (IE/PB Link).
6.1 Configuring the CP 443 − 1 Advanced as a PROFINET IO
Controller
PN IO System in STEP 7
In principle, you configure for PROFINET IO as follows:
To be able to use the CP as a PROFINET IO controller, create a PROFINET IO
system in STEP 7 / HW Config. You can either assign an existing or a new
Ethernet subnet to the CP as the PROFINET IO system.
Then add the PROFINET IO devices to the PROFINET IO system. STEP 7
automatically assigns addresses that you can modify if necessary. The address
information is stored in the database of the CP. When the system starts up, the
PROFINET IO controller (CP) no transfers this address information to the IO
devices (Note: The I/O and diagnostic addresses remain on the IO controller).
