of the whole system, including PLC or master equipment.
0
8E
Current value
"under"
Not used with the FD-S series. R WORD 0 -
8F
Current value
"over"
If the instantaneous flow rate values
for sensor amplifiers (ID 01 to ID 04)
are "over" (FFFF), they are output by
assigning them to bits 0 - 3.
R WORD 0
0: Normal value
1: Over
90
Current Value
ID01
Reads the instantaneous flow rate
from ID 01. Same as the current value
(instantaneous flow rate) used in I/O
communication.
