DST Offset (hh:mm)
This setting determines the daylight savings time offset applicable to your
location. The DST offset is the amount of time that the clock is moved when
Daylight Savings time begins or ends. For example, an entry of +01:00 sets a
daylight savings time offset of one hour. Setting DST offset to 0 (zero) disables
daylight savings entirely. Specify a positive (+) or negative (–) offset with the
Navigation buttons. The value must be non-zero before you can change its sign.
NOTE
The Clock Module’s
DST Start
and
DST Stop
setup registers control the start and end times for Daylight
Savings for up to twenty consecutive years. These registers are already configured in the factory. To
change them, you must use Designer.
Sync Type
This setting specifies whether time synchronization signals are received in UTC
(Coordinated Universal Time) or Local Time. The default is set to UTC for ION
Enterprise. Some DNP masters use Local Time.
Sync Source
This setting determines the port responsible for receiving the time synchronization
signals. Only signals received on the selected port are used to synchronize the
meter’s internal clock; time synchronization signals on all other ports are ignored.
The choices are ETHERNET, COM1, COM2, and COM3. The default is COM1.
Refer to the Time Synchronization and Timekeeping technical note for more details on
synchronization sources.
Clock Source
This item determines the time synchronization source. The meter clock can be
synchronized externally from the line frequency (Line Freq), or from an internal
crystal (Internal), or through a communications port (COMM). The default is Line
Freq. If you are using GPS time synchronization, change this setting to COMM.
Set Meter Time
The Set Meter Time sub-menu contains settings for the date and time displayed on
the front panel. The Meter Time settings are dependent upon the configuration of
the Clock Setup menu–-you must set the time zone offset (TZ Offset) prior to
setting the Local Date and Time.
Local Date
Use this item to set the meter’s display to the current date. The format of the date
is defined in the General Format Setup menu.
Local Time
Use this item to set the meter’s display to local time.
