Modbus value from 2 registers - AlexLV - 09.11.2022
Hi,
how create Modbus profile or read info located in 2 registers:
927-928 AHU consumption, Day RO unsigned int 0 - 4294967296 Wh
929-930 AHU consumption, Month RO unsigned int 0 - 4294967296 Wh
931-932 AHU consumption, Total RO unsigned int 0 - 4294967296 Wh
I usually used modbus profile generator or created it manually, but from one register. Here I have 2 register's located data.
What variant can I use?
BR,
Alex

Set datatype/bus_datatype to uint32.

Thanks, but does it mean in profile I need input just first register?

Correct, you specify the starting register address. The number of registers to read is based on the datatype. uint32 = 2x 16-bit registers.
Use read test to verify that the starting address and read_swap is correct.
