Siemens SINAMICS - Page 74

The pair of keys is created individually for the appropriate SINAMICS drive interface. This
ensures that the address requested matches the SINAMICS drive reached during the HTTPS
access.
Note
Encrypted access to the SINAMICS drive is only possible using the name or IP address of the
interface specified when the key was created.
The certificates are handled as follows:

Delivery state
When using HTTPS for the first time, a private key is generated on the device as a file. This
means you can access the drive via HTTPS in the as-delivered condition of the converter.
When accessing via HTTPS using this key, you will receive a warning in your browser because
the certificate is unknown.
Validity period of the certificates
Certificates up to 2044 are valid.
After expiration of the validity period, install new valid certificates on all the relevant drives.
