Acronym/Term
Definition
A/D converter
Converts analog to digital value.
Analog input module
This module converts analog voltage/current input to digital
value. It has a resolution of 14 and 16 bits.
Channel
Related with the terminal of analog I/O module and
connected to various voltage/current I/O devices,
respectively, with applicable data and diagnosis function.
Conversion time
Time taken by an analog input module to sample and
convert the analog signal to digital value. Also, it refers to
the time taken by an analog output module to convert a
digital value to analog value.
D/A converter
Related with the output module, it is used to make
continuous size of analog voltage and current signal
proportionately to the digital value.
Full scale
Defined as the size of voltage/current where the normal
operation is executed.
Full scale error
Displays the graph difference between agreeable analog-
converted value and actual analog-converted value.
Full scale range
Displays the difference between the maximum and the
minimum of the analog input.
LSB
Least significant bit (LSB) displays the minimum value of the
bit unit.
