(Note 1): In the analog input unit Ver.1.1 or earlier or the analog I/O unit, a digital conversion value equivalent to the
analog input of approx. 2 V is saved in the device (WX), for the channels to which no input is connected. The
analog input unit Ver.1.2 or later are equivalent to approx. 0V.
 -5V to +5V DC input (14-bit mode only)
