1. Setting the Conversion Conditions
First, set the conditions for executing analog input.
Resolution
”Resolution” signifies the number of bits used by an analog input device to represent analog signals.
The higher the resolution, the more finely the voltage range is segmented, allowing the device to
convert analog values to digital equivalents more precisely.
A device with a resolution of 12-bit divides the range width into 4096 segments.
When the device covers the range of 0 - 10 volts, the minimum unit of converted voltages is 10÷4096
≠
2.44mV.
If the device has a resolution of 16-bit, it is 10÷65536
≠
0.153mV instead.
AD12-8(PM)
: The resolution is 12-bit.
Input Mode
This device has single ended inputs only. This cannot be changed.
Channel
A channel indicates a single analog input point.
See "Connector Pin Assignment" in Chapter 3 for details of the channel numbers.
You can perform analog input for the desired number of inputs by specifying the channels in the
software.
Range
The range means the permitted voltage range for analog input.
The input range for this device is fixed at -10 - +10V.
