1005 (03ED) ✓ × The unit used by the parameter that
reads or writes the instantaneous flow

The setting can be changed by C-48,
Flow rate unit (communication).

× The unit used by the parameter that
reads or writes the total flow volume
can be read out.
The setting can be changed by
C-50, Totalized flow rate unit
(communication).
z Example of combining decimal point position and unit:
When the values read for the full scale flow rate, the flow rate digits after the
decimal point (communication), and the flow rate unit (communication) are 5000,
2, and 1 (L/min) respectively, the actual full scale flow rate is as follows.
• Add a decimal point according to the flow rate digits after the decimal point
(communication) setting: 5000
→
50.00
• Add the unit: 50.00
→
50.00 L/min
When writing fixed-point data, use the reverse procedure and write the separated
values.

 If the operation mode is defined by C-16
(Operational mode at error occurrence)
or by C-10, C-11, or C-12 (Digital input
1–3 function assignment), the setting
cannot be changed by communication.
If writing is attempted, a normal
response will be returned.
The operation mode will be “3” (fixed
valve MV) only if “4” (Fixed valve MV)
is set for C-16 (Operational mode at
error occurrence) and an error occurs.
The setting cannot be changed by
communication.
