Weather station Interface
The
Weather station interface
enables connection of a “Davis - Vantage pro2” weather
station to the system. The weather station supplies the controller the following data:
1.
Barometric pressure
2.
Ambient temperature
3.
Humidity
4.
Wind speed
5.
Wind direction
6.
Solar radiation
7.
Daily rain
8.
Rain rate
9.
UV radiation
10.
Evapotranspiration
11.
Dew point
The information is transferred by communication through the RS 485 line.
The
Weather station
is defined during the configuration process when defining the hardware
in use. The Weather station interface will be defined as an analog interface of the type
DAVIS
.
Like any other interface it has an address switch that has to be set according to the definition
made at the configuration process.
The eleven sensors will be automatically defined along with the weather station; they need not
be defined separately. The scale range of the sensors of the weather station is automatically
adjusted and need not be touched.
