2. Example of program 1 (For FX3U, FX3UC Series PLC)
• For example, create the following program to change the digital input data of the 1st analog special
adapter:
M8001
M8260 Sets the input mode of channel 1 to the voltage input mode
(0 V to 10 V)
M8002
RST D8268.6
RST D8268.7
Error status: b6 = OFF
Error status: b7 = OFF
M8000 FNC 12
MOV K1 D8264 Sets the averaging time to "1" for the channel-1 data
M8002 FNC 12
