3. Example of program 2 (For FX
• For example, create the following program to change the digital input data (D110) of the 1st analog special
adapter:
M8001
M8000
M8002
M8000

4. Cautions regarding programming
• GX Developer version 8.13P or later supports scaling instruction (SCL/FNC 259).
• If the A/D converted digital value is out of the data table range specified by the scaling instruction (SCL/
FNC 259), the FX Series PLC will detect an operation error (error code: K6706).

5 Changing of Input Characteristics
Sets the input mode of channel 1 to the
voltage input mode
(0V to 10V).
Error status: b6 = OFF
Error status: b7 = OFF
Sets the averaging scaling to "1"
for the channel-1 data.
Check to make sure the digital
value (D110) is in range.
Calculation for changing input
characteristics.
Stores the operation result in D100.
