3.1.2 I/O conversion characteristic
The I/O conversion characteristic represents the angle formed by a straight line
connecting the "offset value" and "gain value" when the analog signals (voltage or
current input) from outside the PLC are converted to digital values.
Offset value
The offset value denotes the analog input value (voltage or current) that makes the
digital output value 0.
Gain value
The gain value denotes the analog input value (voltage or current) that makes the
digital output value:
4000 (in normal resolution mode)
12000 (when 0 to 5 V, 1 to 5 V, 4 to 20 mA, 0 to 20 mA or the user range setting is
selected in high resolution mode)
16000 (when -10 to 10 V or 0 to 10 V is selected in high resolution mode).
