2.4 Input/Output Conversion Characteristics
I/O characteristics are displayed as a slant of the line connecting offset value and gain value in converting an
digital signal from the external PLC into an analog signal(voltage or current).
Offset value and Gain value of D/A converter are fixed and should not be modified.
Input/ output conversion characteristic example is shown on Fig 2.1
[Fig 2.1] Input/ output conversion characteristic example
