1) Select the SNTP Servers tab.

The SNTP Server Editor dialog box opens.
2) Select the Unicast or Broadcast mode.

If you select Unicast mode for a processor the controller will wait to be
polled by a client and then respond with a time signal; it will not broadcast any
time signals.

If you select Broadcast mode for a processor the controller will regularly
braodcast: it will also respond to unicast polling requests on that interface.
Note: If you set a processor Broadcast IP Address to zero (0.0.0.0) it will disable
the server on that interface.
3) Set the Broadcast IP Address for the network.
4) Repeat steps 2 and 3 for each additional processor module.
5) Click Apply.
Using the Controller as a Modbus Slave
The AADvance controller can operate as a Modbus slave, supporting up to ten
Modbus slaves on each 9110 processor module. This gives a capacity of thirty
Modbus slaves for a controller with three processor modules.
Note: As a Modbus slave device, the controller only transmits data upon a request
from a Modbus master, and does not communicate with other slaves.
