Based on this information, the astronomical position sensor application on the SmartServer calculates
the position of the sun relative to the SmartServer and stores this information in nvoElevation_005 and
nvoAzimuth_005
SNVT_angle
_
deg
data points. The SmartServer then uses the data points to
calculate the sunrise and sundown times and stores the results in nvoSunrise and nvoSunset
SNVT_time_stamp
data points. The information in these data points is then passed to the Event
Scheduler so you can create events based on the calculated sunrise and sundown times.
Setting the SmartServer Time
For the SmartServer to calculate the position of the sun, you need to store the time of day on it. You
can do this in two ways: you can add an SNTP time server to the LAN on which the SmartServer
resides, or you can manually configure the time.
Adding an SNTP Time Server
To add an SNTP server to the LAN, follow these steps:
1.
Right-click the
LAN
icon or a dial-out connection icon, point to
Add Host
, and then click
Server
(LNS, E-mail, Time, IP 852 Config, WebTarget)
on the shortcut menu, or if are you adding the
time service to an existing server on the LAN, skip to step 4.
2.
The
Setup – Host
Web page opens, and a server icon is added one level below the LAN icon at
the bottom of the navigation pane or one level below the dial-out connection icon.
3.
Enter the IP address or hostname of the SNTP server and then click
Submit
. The server icon in the
tree is updated with the IP address or hostname you entered.
4.
Right-click the server icon, point to
Add Service
, then and click
Time
(SNTP)
on the shortcut
menu.
