One characteristic of digital circuit is its fast response to high or low sig-
nal. This kind of response is highly needed for harsh and critical indus-
trial operating environment.
Generally, Digital Input and Output are signals to control external devices
that needs On/Off circuit or TTL devices. Detailed signal assignment
