6.5 Measured value and parameter registers
The register range 30001 to 35000 of the LAMBRECHT sensors is intended for measured values.
Register for wind speed and wind direction.
Register
address Parameter name Unit Factor Description
30001 Wind speed instantaneous value m/s 10 1 decimal place INT
30002 Wind speed average value since last
retrieval
m/s 10 1 decimal place INT
30003 Wind speed maximum value m/s 10 1 decimal place INT
30004 Wind speed minimum value m/s 10 1 decimal place INT
30201 Wind direction instantaneous value ° 10 1 decimal place INT
30202 Wind direction average value since
last retrieval
° 10 1 decimal place INT
30203 Wind direction maximum value ° 10 1 decimal place INT
30204 Wind direction minimum value ° 10 1 decimal place INT
Note: The values from the registers with the maximum values and minimum values are automatically reset as soon as the
register with the average values has been read out.
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)..
The LAMBRECHT sensors give 0xD8F1= 9999(16bit) as error code or invalid value.
6.6 Sensor parameters / Confi guration parameters
Register address 40001 to 46000 contains the confi guration parameter of the sensor.
Register
address Parameter name Unit Divisor Description
40001 Modbus device address 1 The addresses 1...247 are allowed.
40200 Baud rate 0,01 96=9600
192=19200
384=38400
46000 Number of mapping registers 1 Contains the number of occupied map-
ping registers for the autoconfi guration INT
6.7 Mapping register for autoconfi guration
Registers address 46001-49000 containing for each sensor the available registers with measured values and sensor data
from the range 30001-35000.
The registers can only be read out as a block! The length of the block or the number of available mapping registers
is in holding register 46000.
For example, in the ARCO-Modbus wind sensor, registers 46001 to 46004 contain valid addresses. The holding register 46000
contains the number of registers 8. All 8 registers must be read out in the block with the instruction
0x04 . Too many registers
or too few lead to an error message.
