Time synchronization with NTP
This section describes the operational specifications for the NTP client.
-
When starting time synchronization:
The NTP client on the MMB synchronizes the time at the start of operation, irrespective of the
time difference with the NTP server.
The NTP client on the MMB starts operation:
time difference with the NTP server.
The NTP client on the MMB starts operation:
-
when the NTP services on the MMB are enabled (i.e., when [Enable] in the [NTP] field
is checked and the [Apply] button is clicked in the [Network Configuration] - [Date/Time]
window), or
is checked and the [Apply] button is clicked in the [Network Configuration] - [Date/Time]
window), or
-
when the MMB is reset, the MMB redundancy is switched, and the AC power is turned
from OFF to ON while the NTP services on the MMB are enabled.
from OFF to ON while the NTP services on the MMB are enabled.
-
When starting time synchronization:
The time-adjusting method on the NTP varies depending on the NTP operation mode (Step mode
or Slew mode).
or Slew mode).
In Step mode, if the time difference between the synchronized NTP servers and the MMB is:
(1) within a range of -0.128 to +0.128 seconds, the NTP executes Slew adjustment, which
corrects the time at a rate of up to 0.0005 per second without reversal.
(2) outside a range of -0.128 to +0.128 seconds and within a range of -1000 to +1000
seconds, the NTP executes Step adjustment. (In this case, the clock may be reversed.)
(3) outside a range of -1000 to +1000 seconds, the NTP function stops.
In Slew mode, if the time difference between the synchronized NTP servers and the MMB is:
(1) within a range of -600 to +600 seconds (10 minutes) , the NTP executes Slew
adjustment, which corrects the time at a rate of up to 0.0005 per second without
reversal.

(2) outside a range of -600 to +600 seconds (10 minutes) and within a range of -1000 to
+1000 seconds (16 minutes and 40 seconds) , the NTP executes Step adjustment. (In
this case, the clock may be reversed.)

(3) outside a range of -1000 to +1000 seconds (16 minutes and 40 seconds) , the NTP

Time synchronization interval
The NTP client synchronizes at an interval of 64 to 1024 seconds. The initial synchronization
interval is 64 seconds. As the synchronization accuracy becomes stable, this interval gradually
doubles from 64 seconds to 128 seconds, then to 256 seconds, then to 512 seconds, and finally
to 1024 seconds.
