3
Communicating with the FD-S series
*1 "Status details" (page 3-7)
*2 "Error information list" (page 3-8)
*3 The function of DL-DN1 only, which responds to explicit messaging synchro-
nously with I/O communication. This function does not guarantee synchronism
of the whole system, including PLC or master equipment.
0
8E
Current value
"under"
Not used with the FD-S series.
RWORD0-
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.
RWORD0
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.

Current Value
ID04
Reads the instantaneous flow rate
from ID 04. Same as the current value
(instantaneous flow rate) used in I/O
communication.
