Key files

Encryption methods
You need two key files for the encryption method used by the Secure Socket Layer protocol.
● A public certificate
● A private key
The pair of keys is created individually for the appropriate SINAMICS drive interface. This
ensures that the address requested matches the SINAMICS drive accessed during https
communication.
Note
Encrypted access to the SINAMICS drive is only possible with the interface identifier (name
or IP address) specified when the key was created.
You can find further information about Secure Socket Layer certificates at
http://www.verisign.de
As delivered
A standard certificate is supplied so that you can access the drive via https in the SINAMICS
as delivered.
When you attempt https access using the supplied standard certificate, you will be warned
that the certificate is unknown and that the current address of the SINAMICS interface does
not match the setting in the certificate.

Transferring key files to the SINAMICS drive

To enable access to the SINAMICS via https, you must transfer the key files
"MWSSLCer.pem" and "MWSSLKey.pem" to the memory card of the SINAMICS drive.
In order to copy the key files onto the memory card you need a memory card reader/writer.
Procedure
Copy the "MWSSLCer.pem" and "MWSSLKey.pem" files on the memory card to the
\OEM\SINAMICS\HMICFG directory.
