5.4 Flow rate 20 mA
Description: Flow rate end of scale of analog output.
Flow rate 20 mA contains the numerical value of the flow rate corresponding to the end of
the scale of the analog output (20 mA) in the flow rate units programmed into the device.
Variable is a floating point 32-bit IEEE 754. To access this data on the device is
necessary to access two 16-bit registers.
Address 0x3004h corresponds to the most significant 16 bits and address 0x3005h to the
least significant 16 bits.
Supported functions: Read Holding Registers. (0x03h)
Write Single Register. (0x06h)
Write Multiple Registers. (0x10h)
Addresses: 0x3004h 16 bit 20 mA MSB
0x3005h 16 bit 20 mA LSB
5.5 Totalizer units
Description: Contains the code corresponding to the totalizer units of the converter. It is
a 16 bits integer data type (see totalizer code table).
Supported functions:
Read Holding Registers. (0x03h)
Write Single Register. (0x06h)
Write Multiple Registers. (0x10h)
Address: 0x3006h 16 bit Totalizer units
