b) When the Energy Meter address or communication baud rate change, the meter will work under the new
address or communication baud rate after the communication baud rate responded with returned primary address
and communication baud rate.
c) 16 bits int - represents a 16 bit signed integer, 32 bits int - represents a 32-bit signed integer, 32 bits uint -
represents a 32-bit unsigned integer, 32 bits real - represents a floating-point number, and string - represents a
string.
d) Under default, in order to be compatible with previous devices, the low half word of the output data is in the
front, the high half word is in the back, and the high byte of the low half word is in the front, the low byte is in the
back, and the high byte of the high half word is in the front, the low byte is in the back, that is, the CDAB form. If
the device needs to output the high half word before the low half word, and the high byte of the high half word in
the front and the low byte in the back, and the high byte of the low half word is in the front and the low byte is in
the back, that is (ABCD form), so refer to Fuji instruction to send "mpas0" command, and analyze the data
through the following table.
Register
address
Register Data description Data type Remarks
$0000 40001 Flow velocity (high half word)
32-bit floating
point number
The value changes according to
the change of flow rate unit
$0001 40002 Flow velocity (low half word)
$0002 40003
Flow - unit in hours (high half
word)
32-bit floating
point number
$0003 40004
Flow - unit in hours (low half
word)
$0004 40005
Integer part of flow positive
accumulation (high half word)
32-bit signed
integer
$0005 40006
Integer part of flow positive
accumulation (low half word)
$0006 40007
Fractional part of flow positive
accumulation 16-bit signed
integer
The value changes according to
the change of the flow unit, and
the number is expanded by
10000 times before output, so the
real value needs to be reduced by
the same multiple
$0007 40008
Integer part of flow negative
accumulation (high half word)
32-bit signed
