DO means Digital Output
DI means Digital Input
DO or DI signal can have only two state 0 (Low = 0V ) or 1
(High = supply votlage i.e 5V / 12V /24V etc.).
In case of any floating value of signal state,either for
input or output, maloperation is possible depending upon
type of input or output deivice connected to it.
Normally less than 2/3 of supply voltage is not acceptable
for digital signal.
