Signal name Function
Data Output This signal indicates the
Completion timing to load the output
signal data from DO0 to DO15
to the User (PLC Link).
This signal is ON, which
means that the data is
output from the Sensor
Controller.
The user (PLC) reads
the data when this sig-
nal turns ON.
Depending on the
measurement flow set-
tings, the GATE output
may start while the
BUSY signal is ON.
Note that the OR signal
does not necessarily
work together with the
GATE signal.

flow , the Data
Output Request
(DSA) signal is ON,
and preparations for
data output have
been completed.
*1: This occurs when
the Output Unit is
executed as the
measurement flow is
executed in order
from the top. It does
not occur when exe-
cution of a measure-
ment is completed.
*2: The signal is out-
put if a Parallel
Judgement Output
or Parallel Data
Output processing
item is set in the
measurement flow.
ON to OFF
No Handshaking:
The signal turns OFF
after the set output
time has elapsed.
