Connect the terminals of the Analog Input Terminal for each Input Unit accord-
ing to the following diagrams, depending on whether a voltage input or a cur-
rent input is being used.

Short the corresponding V+ and I+ terminals when
inputting a current, using the enclosed short bars.
The analog data that is input can be converted to digital data according to the
input range, as described here. If the input exceeds the input range, the AD
conversion data will be fixed at the upper or Low Limit.
The voltage range 0 to 5 V corresponds to 0000 to 1770 hex (0 to 6,000). The
convertible data range is FED4 to 189C hex (
ages are expressed as two's complements (16 bits). When a disconnection
occurs, the data equivalent to 0 V input will be used (0000 hex).

The voltage range 1 to 5 V corresponds to 0000 to 1770 hex (0 to 6,000). The
convertible data range is FED4 to 189C hex (
below the input range (input voltage less than 0.8 V), a disconnection is
detected and the data is set to 7FFF hex.
