Figure 78: SNTP configuration settings
The following settings are available.
Function
Range: Enabled, Disabled
Default: Disabled
This setting enables and disables the SNTP protocol.
Server IP Address
Range: standard IP address
Default: 0.0.0.0
This setting specifies the SNTP/NTP server IP address.
To use SNTP in unicast mode, this setting must be programmed to the SNTP/NTP server
IP address. Once this address is set, the D90
SNTP/NTP server. Since many time values are obtained and averaged, it generally takes
three to four minutes until the D90
server. It can take up to two minutes for the D90
server is offline.
To use SNTP in broadcast mode, program this setting to "0.0.0.0". The D90
to SNTP messages sent to the all ones broadcast address for the subnet. The
Plus
D90 waits up to eighteen minutes (1024 seconds) without receiving an SNTP
broadcast message before signaling an SNTP self-test error.
UDP Port Number
Range: 0 to 65535 in steps of 1
Default: 123
This setting specifies the UDP port number for use with the SNTP protocol.
Ethernet Interface
Range: 1, 2, or 3
Default: 1
This setting selects the Ethernet port to use for SNTP communications. Port 1 on slot D at
the back of the device is intended for configuration and file retrieval and has a
dedicated IP address. Ports 2 and 3 on slot C are intended for SCADA and peer-to-peer
messaging.
Do not set more than one protocol to the same TCP/UDP port number, as this results in
unreliable operation of those protocols.

The D90 contains an embedded web server and can display pages in a web browser.
The web pages are organized as a series of menus that can be accessed starting at the
Plus
D90 main menu. Web pages are read-only and are available showing DNP and IEC
60870-5-104 points lists, Modbus registers, event records, fault reports, and so on. Enable
