Acronym/Term
Definition
Linearity error
Analog I/O is related between continuous voltage/current
value and digital value, whose agreeable I/O value is
defined as a line within a distance of the minimum 1LSB of
voltage/current. I/O linearity error is regarded as the
declination between the agreeable-converted value and the
actual-converted value on the graph.
Multiplexer
A switching circuit where many signals share one A/D
converter or D/A converter.
Analog output module
A module with an output circuit to convert analog DC voltage
or current signal proportionate to digital value delivered to
the module from the processor.
Resolution
The minimum value recognizable by a measuring
instrument, which is usually displayed in engineering units
(1mV) or the number of bits. In other words, 16383 types of
output are available for 14 bits.
Filter
Used to reduce the change in digitally-converted value by
sudden change in the external noise or input for the analog
circuit, through Software and Hardware filters.
Accuracy
Displays the maximum declination between agreeable value
and output voltage or current for the whole range of output.
On the other hand, it displays the maximum declination
between agreeable value and digitally-converted input signal
value for the whole range of input. Generally, percentage is
displayed for the full scale. Gain, Offset and Linearity error
are all included in the error type available.
Output accuracy
Displays the difference between the actual analog output
voltage/current value and the agreeable-converted value on
the conversion graph for the full scale, with Offset, Gain and
Drift error factors included as well as normal temperature
(25°) and available temperature range displayed,
respectively.
