Three methods for network time synchronization are available in the Metasys system, including Windows Simple Network Time Protocol (SNTP) time synchronization, Multicast, and BACnet® time synchronization.
You can use the Microsoft Windows and Multicast methods when an SNTP master time server is available. If the Site Director has no access to SNTP time servers, you can use the BACnet synchronization method.
To enable a time synchronization method, modify the Time Sync Method attribute for the Site. See the Steps for successful time management and Setting the time synchronization method sections.
