3.1.2 I/O conversion characteristics
I/O conversion characteristics are used for converting the digital value written from the
PLC CPU to an analog output value (voltage or current output), and represented by
inclined straight lines when offset and gain values are included.
Offset value
The offset value becomes the analog output value (voltage or current) when the digital
input value set from the PLC CPU is 0.
Gain value
The gain value denotes the analog output value (voltage or current) when the digital
input value set from the PLC CPU is
4000 (in normal resolution mode),
12000 (when 1 to 5V, 0 to 5V, 4 to 20 mA, 0 to 20 mA or the user range setting is
selected in high resolution mode),
16000 (when -10 to 10V is selected in high resolution mode).
