6.1.1.1 Synchronization of the clock via NTP
Ser[LOG] is able to adjust its internal real-time clock via NTP. The NTP server is entered in the "Server
Name" field. Since NTP returns the time in UTC format, the time deviation of UTC is entered in the "Time
Offset" field.
The field "Update interval" is for the configuration of the interval when the clock synchronization should
take place.
6.1.1.2 Data Transfer via FTP - Ser[LOG] as FTP Client
Ser[LOG] has an FTP client. Measured values can be transferred to an FTP server via FTP. Currently
only unsecured FTP is supported. The checkbox "active" activates the FTP function. Up to 2 servers
are supported. If the primary server ("Server 1") is not available, the secondary server ("Server 2") is
used. The default port for FTP is port 21.
Ser[LOG] works in active mode by default but can also be switched to passive FTP via the checkbox
"passive mode". If the server[LOG] is behind a firewall, the firewall may block an incoming connection
while FTP is active. In this case, you should switch to passive FTP (passive mode).
The login data for the FTP server are entered in the fields "User" and "Password".
The "File name" field defines the main name element for the data storage. If you want to avoid overwrit-
ing data, you can activate _YYYYYMMDDD_HHmm in the field "Name extension". This means that the
main component is extended by the date and time of the transmission each time the data is saved.
