Holding Register
Register address 40001 to 49000
Register addresses 40001 to 46000 contain the confi guration parameters of the sensor.
Register address 46001-49000 Contain the available registers for each sensor with measured values and sensor data from
the range 30001-35000.

Register Mask for Autoconfi guration - Mapping Register
Register address 46001-49000. Contains the available registers for each sensor 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 can be
found in holding register 46000.
E.g. at the Modbus-Pro-WG there are valid addresses in registers 46001 to 46004. Holding register 46000 contains the number
of registers 4. All 4 registers must be read out in the block with command 0x04. Too many registers or too few lead to an error
message.

Autoconfi guration
The Modbus sensors from LAMBRECHT meteo off er the possibility of autoconfi guration. This is supported e.g. by the data
logger met[LOG]. For autoconfi guration, the register addresses of the measured values and sensor data available in the register
range 30001 to 35000 are listed as consecutive values in the register range 46001 to 49000 in the LAMBRECHT sensors.
Registers 46001 to 49000 can only be read out as blocks! The length of the block or the number of available mapping registers
can be found in holding register 46000.
Since the addresses from the range 30001 to 35000 are valid for all LAMBRECHT sensors, an address from this range is also
representative of a measured value type.
E.g. register 30401 always contains the instantaneous value of the air temperature. If this register address is not contained in
the list in register range 46001 to 49000, the connected Modbus sensor does not supply an air temperature.
If the autoconfi guration is started with the data logger met[LOG], it queries the existing mapping registers on each COM
interface in the device address range 1...25. For this purpose, the number of mapping registers is read from register 46000
and the register range from 46001 is read as a block.
The following table contains the assignment of the confi guration to the individual (possible) instantaneous value registers of
the sensors. Some sensors supply registers with mean, minimum and maximum values or additional values in addition to this
specifi cation. Unknown register addresses (or registers that are not required) must therefore be ignored during autoconfi guration.
