The SNTP driver will compute a new clock value every 5 minutes using the
average value of 10 samples each collected over an approximate 6-second
period. This new value will be used to adjust the clock maintained by the SNTP
driver and used by the application. If a valid database register is specified, the
driver will place the time value into the module's database. The first two registers
will contain the number of seconds and the next two registers will contain the
number of microseconds since January 1, 1970.
A list of some of the common NTP servers can be obtained at
http://www.ntp.org/ , http://www.eecis.udel.edu/~mills/ntp/servers.html , along with
the appropriate IP address. Other server lists can be found on the Internet by
searching on "NTP Servers" with your browser.
NTP Server IP Address
Enter in dotted notation
This parameter sets the IP address of the NTP server to utilize for time
acquisition. Select an NTP server with the greatest accuracy that can be
accessed all the time from your network. Setting this IP address to 0.0.0.0
disables SNTP server requests.
Time Zone
–11 to 11
This parameter sets the time zone offset from UTC. If UTC time is to be utilized
in the module, set this value to zero. Positive values are for time zones west of
UTC, and negative values are for time zones east of UTC.
Use Daylight Savings Time
Yes or No
This parameter specifies if daylight savings time will be used in the time
computation.
Database Register
–1 or 0 to 3992 as an even value
This parameter specifies if the NTP time computed by the driver is to be placed
into the module's database. If a value of –1 is specified, the time will not be
placed into the database. If the value is between 0 and 3992, the time will be
placed in the database. The first 4 bytes will represent the seconds since
1/1/1970, and the second 4 bytes will represent the number of microseconds. An
even value should be used for the register value in order for the data to be stored
correctly.
