Protection (Tim 1531 Irc); Protection - Siemens SIMATIC TeleControl DNP3 Configuration Manual

You export the certificate of the module for communications partners from third-party
vendors in much the same way as when importing (see above). Follow the steps outlined
below:
1. In the STEP 7 project open the global certificate manager:
Global security settings > Certificate manager
2. Open the "Device certificates" tab.
3. In the table select the row with the required certificate and select the shortcut menu
"Export".
4. Save the certificate in the file system of the PC of the connected engineering station.
Now you can transfer the exported certificate of the module to the system of the third-party
vendor.
Change certificate: Subject Alternative Name
STEP 7 adopts the properties "DNS name", "IP address", and "URI" from the parameter
"Subject Alternative Name" (Windows: "Alternative applicant name") from the STEP 7
configuration data.
You can change this parameter of a certificate inn the certificate manager of the global
security settings. To do this, select the a certificate in the table of device certificates and call
the shortcut menu "Renew". Properties of the parameter "Alternative name of the certificate
owner" changed in STEP 7 are not adopted by the STEP 7 project.

3.18.1

Protection

Protection functions
The module provides various access levels to restrict access to certain functions.
NOTICE
Configuring an access level does not replace the know-how protection
Configuring access levels prevents unauthorized changes to the module by restricting the
download rights.
This does not, however, provide write or read protection for blocks on a memory card. Use
the know-how protection to protect the code of blocks on the memory card.
