Analog Input Units
Section 7-2
Procedure
Writing Set Data and
Reading A/D
Conversion Values
Connect the Analog Input Unit to the CPU Unit.
Connect and wire Units.
Create a ladder program
• Connect Analog Input Units.
• Wire to analog output devices.
• Write set data to output words (n+1, n+2).
• Set use of inputs.
• Select input signals using range codes.
• Set use of averaging.
• Read A/D conversion values from input words
(m+1 to m+4).
• For current inputs, confirm that there is no open
circuit.

Writes the set data (use
of inputs, averaging,
range codes).
Reads the conversion
value.
The last input word allocated to the
CPU Unit or already connected
Expansion (I/O) Unit is m and the
last output word is n.
