SNTP
SNTP
Important pre-condition: The device needs to have access to an SNTP
server via the connected network. This server preferably should be
installed locally.
Principle – General Use
SNTP is a standard protocol for time synchronization via a network. At minimum, one SNTP server has to be integrated
into the network. The device can be configured for one or two connected SNTP servers.
The device's system time will be synchronized by the connected SNTP server 1 to 4 times per minute. In turn, the
SNTP server synchronizes its time via NTP with other NTP servers. This is the normal case. Alternatively it can receive
its time via GPS, radio controlled clock, or the like.
If the server's “Stratum” has been set manually, it is not an indication of its quality or reliability.
