Each register is 4 bytes (2 consecutive holding registers), occupying two addresses (low address addressing);

The shaded registers in the above table are read-only registers, and write operations are invalid;

Address 0x41049 is the Total Flow clear register. Write “0” to this address to perform Total Flow clear operation.

Return 1 (float)

The flow unit setting is 0-7 (convert data to 4 bytes floating point for transmission):

0→t/h；1→kg/h；2→g/h；3→kg/min ；4→g/min；5→m3/h；6→L/min；7→ml/min

Density unit setting is 0-2 (convert data to 4 bytes floating point for transmission):, respectively g/cm³、g/L、t/m³；

0→g/cm³；1→g/L；2→t/m³

Measure medium settings 0-1, representing liquids and gases, convert them to 4 bytes floating point transmission;

1, read N variables

Host request information frame:

Instrument address +0x03+ register start address (2 bytes, upper byte first) + register read/write number 2*N (2 bytes, upper byte first) + CRC check code (2 bytes, lower word)

Slave response message frame:

Instrument address + 0x03+ bytes of data 4*N (1 byte) + register data (4*N byte, upper byte first) + CRC (2 bytes, lower byte first)

Example:

2, write N variables

Host request information frame:

Instrument address + function code 0x10 + register start address (2 bytes, upper byte first) +Register read/write number 2*N (2 bytes, high byte first) + data byte 4*N (1 byte) + data to be written (4*N bytes, upper byte first) + CRC (2 Bytes, lower byte first)

Slave response message frame:

Instrument address + function code 0x10 + register start address (2 bytes, upper byte first) register Reader read/write number 2*N (2 bytes, upper byte first) +(2 bytes, lower byte first)
