*1. If the data exceeds the range, the maximum value of the range is read.
*2. For the number of decimal places and the unit of data, see “Totalized flow rate digits after the decimal point” (address
1004) and “Totalized flow rate unit” (address 1006).
Note: If the upper and lower digits/bits are divided into two frames during writing, the total flow volume may be updated
between the frames, so an unintended value may be written, depending on the timing. Write data consecutively to
keep them in one frame whenever possible.
z Example of total flow volume-related data combination:
When the values read for the total flow volume are 1234 (upper bits) and
5678 (lower bits), and if the totalized flow rate digits after the decimal point
(communication) is set to “2” and the totalized flow rate unit (communication) is
set to “1” (L/min), the actual total flow volume is as follows.
• If C-47, Totalized flow rate communication data format, is set to “0” (first 4 digits
+ last 4 digits)
(1) Combine the upper and lower digits: 1234, 5678
→
12345678
(2) Add a decimal point according to the totalized flow rate digits after the
decimal point (communication) setting: 12345678 → 123456.78
(3) Add the unit: 123456.78
→
123456.78 L
• If C-47, Totalized flow rate communication data format, is set to “1” (upper 16
bits + lower 16 bits)
(1) Convert the upper and lower bits to hexadecimal numbers: 1234, 5678
→
0x04D2, 0x162E
(For CPL communication RD commands and Modbus communication, data
is originally hexadecimal.)
(2) Combine the upper and lower bits: 0x04D2, 0x162E → 0x04D2162E
(3) Convert to a decimal number: 0x04D2162E
