3.1.3.14 SNTP
Simple Network Time Protocol (SNTP) is used to synchronize the clocks of networked
computer systems. The SNTP protocol uses the request and response message
exchanges for the client to adjust the time according to the SNTP server. The ESML6-P3
can work as an SNTP client to calibrate time based information from a SNTP or NTP
server. It can support four SNTP servers at one time. The SNTP client’s request is
broadcast to the SNTP server and the client takes the first one to respond as the ‘active’
server whilst the others are in stand-by mode.
Fig 3-45 SNTP
Enable SNTP Status, the default is disabled, configure the SNTP server’s IP address and
set the interval time to between 16 and 16284 seconds to configure the period for the
synchronization message to be sent. Set the time zone, the default 0 is set as GMT and
the time should be adjusted according to the time zone. The Server Time shows the time
it takes to get from the active SNTP Server and Device Time shows the local time in the
device. Update can be set to either auto or manual, the default is none. The Server state
shows whether the server is providing the SNTP time for the device or is in stand-by
mode.
