7.1 LAMBRECHT meteo – Auto-configuration
The Modbus sensors from Lambrecht meteo offer the possibility of auto-configuration. This is
supported e.g. by the Lambrecht meteo data logger met[LOG]. For the auto-configuration, the register
addresses of the measured values and sensor data available in the register range 30001 to 35000 are
listed as successive values in the Lambrecht sensors in register range 46001 to 49000. Registers
46001 to 49000 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.

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. If this register
address is not included in the list in register range 46001 to 49000, the connected Modbus sensor
does not supply an air temperature.
If the auto-configuration is started with the data logger met[LOG], it queries the available 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 starting at 46001 is read out as a
block.
The following table contains the assignment of the configuration to the individual (possible)
instantaneous value registers of the sensors. Some sensors deliver registers with mean (average),
minimum and maximum values or additional values beyond this specification. Unknown register
addresses (or registers that are not required) must therefore be ignored during auto-configuration.
