9.2.2.1.5 Time Master
If the controller can be a BACnet Time Master, this screen lets you
confi gure how it sends time synchronization broadcasts.
Figure 24
Time Sync Mode - Tap in the number below that represents your
selection:
—
0 = No Broadcast - The controller will not act as Time
Master.
—
1 = Local Broadcast - If it doesn't already exist, a
BACnet address with network number and MAC address
length both set to zero is added to the controller's Time
Synchronization Recipients list found on the driver's
Device page in WebCTRL®. The controller will then send
time broadcasts only to controllers on its ARCnet or MS/
TP network.
—
2 = Global Broadcast - If it doesn't already exist, a global
address with network number set to 65535 and MAC
address length set to zero is added to the controller's
Time Synchronization Recipients list found on the driver's
Device page in WebCTRL®. The controller will then send
time broadcasts to all its connected networks.
Time Sync Interval - Enter how often local or global time
broadcast should be sent (1-9999 minutes). If Time Sync Interval
is set to zero, no time sync messages are sent.
If the controller looks through its Time Synchronization Recipient
List and fi nds an entry with MAC address length set to zero and
network number set to 65535, the controller's BACnet Time
Master mode is set for Global Broadcast. If there is no global
broadcast entry in the recipient list, the controller then looks for
a local broadcast address (MAC address length set to zero and
network number set to zero or to the same network number as
the module's). If such an entry is found, the BACnet Time Master
mode is set for Local Broadcast. Otherwise, the mode defaults to
Disabled/None.
