6) Program example
Distinction program of A/D conversion value (Analog input range: 4∼20 ㎃)
a) Program explanation
- When digital value of channel 0 is the same or more than 2000 and the same or less than 3000, %QX0.0.0 is On
-When digital value of channel 1 is the same or more than 2000 and the same or less than 3000, %QX0.0.1 is On
- When digital value of channel 2 is the same or more than 2000 and the same or less than 3000, %QX0.0.2 is On
- When digital value of channel 3 is the same or more than 2000 and the same or less than 3000, %QX0.0.3 is On
b) System configuration
(a) Analog parameter settings
• Channel “0”, “1”: voltage input (0∼10VDC)
• Channel “2”, “3”: current input (DC 4∼20 ㎃)
