9410 series Time and timekeeping
6. Select the parameter that you want to configure and click Edit. Enter the
password if prompted.
Parameter Value Description
Timezone
–
Sets the timezone based on the timezones available from the computer’s operating
system.
NOTE: This is also where you can synchronize your meter’s DST settings with
the computer’s.
Time sync type Local time or UTC Specifies the time format of the time sync message:
• UTC: Coordinated Universal time: for the purposes of meter configuration, it is
equivalent to Greenwich Mean Time (GMT).
• Local time: the local time, with DST and timezone information applied.
Time sync source COM1, Ethernet, Ethernet
- ION, Ethernet - DNP,
IRIG-B
Sets which device port accepts time synchronization messages.
Time synchronization messages on other ports are ignored.
Clock Source Internal, Line frequency,
COMM
Sets the source for the clock:
• Internal: the meter’s internal clock.
• Line frequency: the frequency of the measured power system as the clock
source.
• COMM: the meter’s communication port (used by the GPS time sync source).
DST Offset Numeric Bounded Format/
Elapsed Interval Format
Specifies the amount of time the meter clock is moved forward when entering
Daylight Savings. A value of zero disables this feature and clock does not adjust for
DST.
Start of the Week Monday - Sunday Specifies the start day of the week used for Trending and Forecasting.
NOTE: Changing the start day of the week clears all trending and forecasting
data.
For SNTP/NTP time synchronization, you must set the Time sync type to UTC
and the Time sync source to Ethernet.
For GPS/IRIG-B time synchronization, you must set the Time sync source to
IRIGB and the Clock Source to COMM.
7. For SNTP/NTP time synchronization, you must also enter the following
information under Communications > Advanced Ethernet > NTP:
Parameter Value Description
Enable NTP Time Sync NTP, SNTP, No NTP: specifies NTP time synchronization.
SNTP: specifies SNTP time synchronization.
NOTE: SNTP is recommended for revenue-related applications.
No: neither NTP nor SNTP time synchronization are used.
NTP Time Sync Interval Numeric value or elapsed
interval value
Specifies how often the meter synchronizes over SNTP.
NOTE: This parameter is not used for NTP.
NTP Event Logging
Threshold (NTP only)
1000 to 1000000 Specifies the minimum time difference (in milliseconds) for a time synchronization to
be logged as an event.
This parameter can be configured to help prevent the meter’s event log from being
flooded with time synchronization events.
NTP Server Server IP address or
domain name
Specifies the IP address (or fully qualified domain name if DNS is active) of the SNTP
or NTP server.
8. For serial GPS time synchronization, you must also enter the following information
under Communications > Serial settings:
Parameter Description
Protocol Select the GPS setting that matches your GPS receiver.
Baud rate The recommended baud rate for GPS time synchronization is 9600 bps.
Serial port The recommended stop bits/parity for GPS time synchronization is 8N1.
