Configure the Controller as an SNTP Client
The AADvance controller supports the Simple Network Time Protocol (SNTP)
service that can circulate an accurate time around the network. As an SNTP client the
controller will accept the current time from external Network Time Protocol
(NTP) and SNTP network time servers.
The SNTP clients settings tell the controller the IP address of the external server; the
version of SNTP offered by the server; and the operating mode for the time
synchronization signal that the processors will use for their real time clock.
To configure the SNTP clients service do the following:
1) Select the SNTP Clients tab.
The SNTP Clients Editor dialog box opens.
2) Set the E1-1 and E1-2 Address fields to the IP addresses of the network time
server.
Note: The first address represents that of the primary server and the second one
the secondary server for each processor module. At start up the SNTP client will
choose the primary server of the "lowest" slice; if no primary signal is valid the
SNTP client looks for an active secondary server signal.
