UTC Time synchronization
UTC Time synchronization is used by a Time master to notify one or more remote devices of the correct
Universal Time Coordinated (UTC) so that devices can synchronize their internal clocks with one another, and the
intended date and time value is sent as part of the service request.
NOTE:
● UTC Time synchronization has the ability to account for daylight savings time.
● You need to be a part of the recipient list in order to receive a Time synchronization request.
Recipients can be added by recipient device instance number.
1. Navigate to Object view > Device > Infrastructure > the automation station.
2. Click , scroll through the properties and select UTCTime synchr.recipients.
3. Select a recipient in the recipient list.
4. Enter the Network number and MAC address and click in the drop-down to save changes.
 The local time and date is updated by subtracting the value of UTC Offset property from the time parameter.
Time synchronization using Network Time Protocol (NTP)
If a device object has an NTP property, then the device connects with the NTP server every 12 hours and select
the new time. If the time difference between the receiver and the current time is greater than five seconds, the
device automaticallys adjust its time.
NOTE: If the time is less than five seconds, it does not adjust the time.
