Time Sync Tab

Timezone

Specifies the time zone the device's clock uses. Default = UTC-06:00 Central Time (US & Canada).

Time Synchronization Configuration

Click to select or create the Time Sync Object assigned to this device. See the Time Synchronization section for more details.

Enable Time Synchronization

Default = Not selected. Select this to configure and allow time syncs to be performed, either on a scheduled interval or using the "Time Sync" command.

Time Synchronization Interval

Select the desired Time Synchronization Interval relating to the Schedule object assigned on the Connection tab. Time Synchronization checks occur on the frequency of this interval.

Time Synchronization Priority

Low. Queues up with other Low priority items.
Medium (Default). Interrupts Low priority items, and queues up with other Medium priority items.
High. Interrupts Medium and Low priority items, and queues up with other High priority items.

TS/NRT Options

Send NRT on Request. When this option is selected, ACM will send a TS/NRT message upon receiving a TS/NRT request message from the device.

Send NRT on Startup. When this option is selected, ACM will send a TS/NRT message when the device first starts polling in ACM, but only if the Send NRT on Request option is also enabled.

Send NRT on Comm Loss. When this option is selected, ACM will send a TS/NRT message when communication is lost and then reestablished with the device, but only if the Send NRT on Request option is also enabled.

Use RDBE for Time Synchronization

Default = Not selected. Select to use RDBE instead of NRT for time synchronization. For BSAP, the device time can be read or written using either default time items or the RDB Extension read/write time command.

Older Network 3000 devices (model numbers less than 3500) generally don't support RDB Extension messages, so don't check the option to use that. These default time items that are supported by most older Network 3000 devices will be used to read the time are:

#TIME.002. (year)
#TIME.003. (month)
#TIME.004. (day)
#TIME.005. (hour)
#TIME.006. (minute)
#TIME.007. (second)

Teleflows (model numbers 35xx) support RDB Extension messages. Check the option to use that for time sync. Read individual date/time fields with the RDBE Extension message using these extended items:

#TIME_HOUR
#TIME_MIN
#TIME_SEC
#TIME_DAY
#TIME_MON
#TIME_YEAR

ControlWaves support RDB Extension messages and also support the following default time items, so either time sync method will work:

@GV._TIME_002 (year)
@GV._TIME_003 (month)
@GV._TIME_004 (day)
@GV._TIME_005 (hour)
@GV._TIME_006 (minute)
@GV._TIME_007 (second)

ControlWaves can also use the RDBE message extended items that the Teleflows use to read individual date/time fields.
