Page 101 Configuration 4.12 Time-of-day synchronization Basics of time-of-day synchronization With telecontrol applications that require time-of-day synchronization, you need to synchronize the time of day of the CP regularly. If you do not synchronize the time of day, there may be deviations of several seconds per day in the time information of the stations. If security functions are activated, the module also requires the current time.

Page 120: Certificate Manager
If you use communication with authentication for the module, for example SSL/TLS for secure transfer of e-mails, certificates are required. You need to import certificates of non- Siemens communications partners into the STEP 7 project and download them to the module with the configuration data: 1.
Page 121 The table also shows all other certificates generated by STEP 7 and all imported certificates. So that the CP can communicate with non-Siemens partners when the security functions are enabled, the relevant certificates of the partners must be exchanged during communication.

Configuration 4.17 Creating telecontrol connections for the ST7 communication Exporting certificates for applications of third-party vendors (e.g. logging server) For communication with applications of third-party vendors, the third-party application generally also requires the certificate of the CP. You export the certificate of the CP for communications partners from third-party vendors in much the same way as when importing (see above).
