When Host link data output is set for a unit, the measurement results are out-
put in order from the smallest output number.
The measurement results are output in BCD code to the Write Area in the Pro-
grammable Controller.
Each time that data is output, the write flags are switched between
"0000" and "1111". The status of these bits can be monitored to see
when data has been written.
After the first measurement, the write flags are cleared to "0000" so
store "1111" in this digit as the initial value before starting
measurements.

• Digital Output Range
-9,999,999.999 measurement
The minimum value of "-9,999,999.999" will be output for measurements
less than -9,999,999.999.
The maximum value of "9,999,999.999" will be output for measurements
greater than 9,999,999.999.
• JG (Judgement) Outputs
The following values are output when JG (Judgement) has been set:
OK: 0
NG: -1
After measurements have been made in Run Mode, the data up through the
last measurement will be output even if the mode is changed to another mode.
The data output will not be interrupted midway.
Example 1
This example shows the data output when the data 0 measurement is
143.250, data 1 is not set, and the data 2 measurement is -6,943.298.
