Warranty Please note the loss of warranty and non-liability by unauthorized manipulation of the system. You need a written permission of the LAMBRECHT meteo GmbH for changes of system components. These activities must be operated by a qualified technician. The warranty does not cover: Mechanical damages caused by external impacts (e. -
Page 4: Initial Operation
LAMBRECHT meteo | PRO-Modbus Initial operation The wind can be represented by a vector quantity. For a complete description of the wind it is necessary to specify its speed and direction. The two components are subject to spatial and temporal variations; thus, strictly speaking, they are valid only for the site where the measuring instrument is put up. -
Page 5: Maintenance
The sensor design permits long periods of maintenance-free operation. We recommend a regular visual verification and functional test of the wind sensors as well as a sensor calibration of both sensor types at intervals of 2 years. With problems, which you cannot solve, do not hesitate to contact our LAMBRECHT meteo service under: Tel:... -

Electrical connection PRO-Modbus sensors are connected to a data measuring system via the open cable end. The sensors have a cable- plug connection to the cable. The connecting cable is suitably led along the mast between the data evaluation device (indicating instrument or data acquisition system) and the sensor. -

LAMBRECHT meteo | PRO-Modbus Under most climatological conditions the heating prevents blocking of the moving sensor parts (see illustration). The cup rotor or the wind vane are not heated. In case of icing or formation of ice at the moving sensor element the function is restricted for the period of icing. -

Page 9: Modbus Protocol
LAMBRECHT meteo | PRO-Modbus Modbus protocol The LAMBRECHT meteo Modbus sensors and the met[LOG] follow the specification of the Modbus organization: "MODBUS APPLICATION PROTOCOL SPECIFICATION V1.1b3" (see www.modbus.org). 11.1 Data encoding MODBUS uses the "big-endian" format for addresses and data. This means that if a value is transmit-ted with a number format that is larger than a single byte, the "most significant byte" is sent first. For values that go beyond one register (e.g. 32 bit) this is not clearly specified for the Modbus. In these cases (32 bit or 64 bit) the LAMBRECHT Modbus sensors follow the big-endian number format. -

The registers addresses 30001 to 35000 apply to all LAMBRECHT meteo Modbus sensors, but are only available or valid if the respective sensor supports the corresponding values (e.g. a pure temperature sensor does not provide any wind speed).. -

46000. Since the addresses from the range 30001 to 35000 apply to all LAMBRECHT sensors, an address from this range is also representative of a measured value type.For example, register 30401 always contains the current value of the air temperature. - Page 12 LAMBRECHT meteo | PRO-Modbus Register Parameter name Unit Factor Description Data Function Storage type address type code >16 bit 30001 Wind speed 1 decimal place 0x04 Big-Endian instantaneous value WORD 30201 Wind direction ° 1 decimal place 0x04 Big-Endian instantaneous value...
