Modbus combine 2 registers

[thomasoppida]

Hi,
I am doing a modbus integration of a deltaohm weatherstation. 

For rainfall we have 2 modbus adresses (24,25) unsigned 16 bits registers. To get this right the manual says "The
amount of rainfall measurements are 32-bit integer values. Two consecutive 16-bit registers
must be accessed to read a measurement."

How do I do this? Is it possible to set it up in the modbus profile?

Set datatype field to "uint32". You can use read test feature before creating the profile to check if different byte/word swap is needed.

If you read the whole data as array, you can use logic and shift to combine the two registers.
temp = bit.bor(bit.lshift(data[24], 16), data[25])
