Input Mode (Characteristics) BFM#0

For the 4AD, there are two types of input characteristics: voltage (-10 to +10V) and current (4 to 20mA, -20 to
+20mA) input characteristics. The input characteristics depend on the set input mode as described below. For
each input range, there are 3 input modes.
1. Voltage input characteristics [-10 to +10V] (Input mode: 0 to 2)
Set input mode: 0
Input type: Voltage input
