The P03/3-Modbus and P03/3-Modbus-GPS Weather Stations measure temperature, wind speed and brightness (eastern, southern and western sun) and recognize precipitation.
The P03/3-Modbus-GPS additionally receives the UTC signals (Universal Time Coordinated) as well as the site coordinates via an integrated GPS receiver. The direction of the sun (azimuth) as well as its height (elevation) are calculated and indicated, too.
The devices are Modbus slaves with a RS485 interface and a RTU protocol. The Modbus master, such as PC, SPS or MC can read the P03/3-Modbus(-GPS) Weather Stations measurement values with "Function 04h (Read Input Register)".
