configuration and operation of Secure Communication, for example:
• Hypertext Transfer Protocol Secure (HTTPS)
• Secure Open User Communication
• Secure Communication with OPC UA
A public key infrastructure (PKI) can issue, distribute and check digital certificates. For
SIMATIC Drive Controller , you create certificates for various applications in the CPU
properties in STEP 7, for example: TLS certificates for Secure Open User Communication, Web
server certificates, and OPC UA certificates.
SIMATIC Drive Controller as of CPU firmware version V2.9 with STEP 7 and WinCC as of
version V17 support innovative and standardized secure PG/PC and HMI communication -
Secure PG/HMI communication for short.
