Raw ADC Data (In bits)
The analog inputs have 16 bits of resolution (32,767 software counts) spanning over the full range of the
input voltage. Wiring ±10 VDC voltage in single-ended, or ±5 VDC in differential mode produces the
following counts in software:
Single-Ended

Scaled ADC Data (In volts)
For general purpose usage, the ADC data (reported in bits) can be easily scaled and converted into “user”
voltage. In the example PLC below:
The global parameter
ADCnXxxZeroOffset
represents the voltage offset with a zero volt input.
This is user adjustable.
The pointer
ADCnXxx
reports the raw ADC data in software counts, units of 16-bit (±32767).
The global parameter
ADCnXxxVolts
reports the ADC data in “user” volts.
Where
n
is the ADC channel number (1 or 2) of the corresponding
xx
connector (X9, X10, X11, or X12).
