0: The input port is valid when no current passes the
port, and the output port is valid when the switch tube
is open..
1: The input port is valid when the current passes the
port, and the output port is valid when the switch tube
is closed.
Other: Check the current status

Namely, if d3.08 is set to ―110.0‖, it indicates that DIN1 is enabled when no current passes the input port; if
d3.08 is set to ―110.1‖, it indicates that DIN1 is enabled when any current passes the input port.
