About this task

Follow these steps to set the time synchronization method to BACnet for the Site Director. This method is only available to a network engine Site Director. The Metasys Server does not support BACnet time synchronization.

Procedure

  1. Log on the network engine Site Director.
  2. Drag the Device object of the Site Director to the display frame.
  3. Select Advanced.
  4. Click Edit.
  5. Move to the bottom of the window to locate the BACnet time attributes (Figure 1).
    Figure 1. BACnet time synchronization attributes

  6. Under the Time Sync Recipients drop-down list, specify the BACnet recipients (devices) that are to be time synchronized with the local time that is kept by the network engine. For each recipient, define its device ID, IP address information, or broadcast type and information.
    Figure 2. Time Sync Recipient parameters
  7. Under the UTC Time Synchronization Recipients drop-down list, specify the BACnet recipients (devices) that are to be time synchronized with the UTC time that is kept by the network engine. For each recipient, define its device ID, IP address information, or broadcast type and information.
  8. For Time Synchronization Interval, specify the periodic interval, in minutes, at which Time Synchronization and UTC Time Synchronization requests are sent. If you set to zero, then periodic time synchronization is disabled.
  9. For Align Intervals, specify whether clock-aligned periodic time synchronization is enabled. If periodic time synchronization is enabled and the time synchronization interval is a factor of an hour or a day (that is, the value divides without a remainder), then the beginning of the period specified for time synchronization aligns to the hour or day, respectively.
  10. For Interval Offset, specify the offset, in minutes, from the beginning of the period defined for time synchronization until the actual time synchronization requests are set. Interval Offset has no effect when Align Intervals is False.
  11. Click Save.
