ITVL
■ A/D data measurement
Turns ON output relay 0500 when the analog input from the KL-4AD to DM1600
(range: 1 to 5 V) exceeds +3 V. Turns ON output relay 0501 when the input is below
+2 V. Writes the average into DM0100.
Refer to the "KL-4AD/KL-2AD User’s Manual" for data memory settings for the KL-
4AD.

Writes average into DM0100 every 100 measurement.
Measures contents of DM1600.
Sets max. setting value to +3 V (2000).
Sets min. setting value to +2 V (1000).
Sets number of averaging measurements to 100.
Pauses measurement when input relay 0001 turns ON.
Resets measurement when input relay 0002 turns ON.
0500 turns ON when measured value exceeds max. setting value.
0501 turns ON when measured value is below min. value.
