Product overview
3.4 Firmware functions
The PROFINET interface X3 P1 is split internally for the CPU Runtime and the C/C++ Runtime.
Therefore, there is one IP address for the CPU and one IP address for the C/C++ Runtime.
• Set the IP address of the CPU in STEP 7.
You can find additional information in the online help for STEP 7.
• Set the IP address of the C/C++ Runtime in the configuration file of the C/C++ Runtime (see
the section "Initial commissioning").
Note the following restrictions when configuring the PROFINET interface X3 P1 with STEP 7:
• The configuration of the "Transmission rate/duplex" has no effect on the connection to the
PROFINET interface X3 P1 and the C/C++ Runtime.
• The "Monitor" option is not supported.
• Topology configuration is not supported.
