2.4 Characteristic of I/O conversion
Characteristics of I/O conversion are the inclination connected in a straight line between Offset and
Gain values when converting analog signal (voltage or current input) from PLC’s external device to
digital value. I/O conversion characteristics of A/D conversion modules are as described below.
