The following processing is performed during polarity selection C35, C45 and range selection C40.
C35: Set the input range of the AI1 terminal.
C35 Terminal input specifications
0 -10 to 10 V
1 0 to 10 V (A negative voltage is considered as 0 V.)
C40: Set the input range of the AI2 (AII function) terminal.

0 is set as the limit for a value below 0.
1 0 to 20 mA
10 4 to 20 mA
A value below 0 is enabled as a negative value.
11 0 to 20 mA
C35: Set the input range of the AI2 (AIV function) terminal.
