Quick start instructions for commissioning C/C++ Runtime

NOTE
Commissioning the C/C++ Runtime
You require experience in working with Linux systems to commission the C/C++ Runtime.
Two IP addresses of the PROFINET interface X3 P1
The PROFINET interface X3 P1 is (typically) used to:
• Link development tools for C/C++ Runtime applications
• Connect the TIA Portal
• Develop STEP 7 applications
• Communicate from C/C++ Runtime
• Communicate internally between C/C++ and CPU Runtime (via virtual network)

Description
With STEP 7 and WinCC, SIMATIC S7-1500 CPUs and ET
200 CPUs support innovated and standardized secure
PG/PC and HMI communication – referred to as Secure
PG/HMI communication for short.
You have the option of assigning a password for protect­
ing confidential configuration data of the respective CPU.
This refers to data such as private keys that are required
for the proper functioning of certificate-based protocols.
The CPUs feature an integrity protection function by
default. This helps to detect any manipulation of the
engineering data on the SIMATIC Memory Card or during
data transfer between the TIA Portal and the CPU, and to
check communication from a SIMATIC HMI system to the
CPU for possible manipulation of engineering data. The
user receives a corresponding message about manipula­
tion of engineering data detected by the integrity protec­
tion.
The know-how protection protects user blocks against
unauthorized access and modifications.
Copy protection links user blocks with the serial number
of one or more SIMATIC memory cards or the serial num­
ber of one or more CPUs. User programs cannot run
without the corresponding SIMATIC memory card or CPU.
You can assign separate rights to different users via
authorization levels.
As an alternative to manual password entry, you can link
a password provider to STEP 7. A password provider
provides the following advantages:
• Convenient handling of passwords. STEP 7 automatic­
ally reads in the password for the blocks. This saves
you time.
• Optimal block protection, since the users do not
know the password themselves.
