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.
5.2.7 Sequence
Flag
In order to save bandwidth, you can configure the module to use the Sequence
Flag feature using the following parameters:
If this feature is not selected, the module will send the object address and its
value at every monitored response to the master.
If this parameter is selected, the module will turn the Sequence Flag on every
monitored response sending the address for the first point along with all point
values. The MVI56-104S module assumes that all other points use information
object addresses in a contiguous order (using the first point as the reference). So
since the module does not send the address for each point it end up saving
bandwidth communication, increasing the network performance.
Note: Refer to the client device specification to verify if this feature is supported before you
consider using it.
