11
Bit 11 provides 2
the Sign Flag for input ranges that include negative values. The Sign Flag will
be 0 for positive values and 1 for negative values.
Bit 15 is the Disconnection Flag for input ranges of 1 to 5 V and 4 to 20 mA,
and will be 1 when a voltage of 0.5 V or less is detected for 1 to 5 V or when
a current of 2 mA or less is detected for 4 to 20 mA.
