10.7 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 PRO-Modbus wind speed sensor, registers 46001 to 46004 contain valid addresses. The holding register
46000 contains the number of registers 4. All 4 registers must be read out in the block with the instruction
0x04
. Too many
registers or too few lead to an error message.
10.8 Autoconfi guration
The Modbus sensors from LAMBRECHT meteo off er the possibility of auto-confi guration. This is supported e.g. by the data
logger met[LOG].
For the 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 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 autoconfi guration 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 from 46001 is read out 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 deliver registers with mean, minimum and maximum values or additional values beyond this speci-
fi cation. Unknown register addresses (or registers that are not required) must therefore be ignored during autoconfi guration.
