0
Active High
1
Active Low
Table 2: Active High/Low
By default, the inputs are configured to
Active High
, an ON response is achieved when the input is
grounded.
An active high or low signal could be read by selecting the appropriate pull-up or pull-
down 10kΩ
resistor, as shown in the following table.

Table 4: Digital Input Types
By default, the
Normal Logic
type
is used for the digital input.
In
Normal Logic
mode, the input state is 1 in case the input signal is interpreted as an ON-signal.
The input state turns 0 if the input signal is interpreted as an OFF-signal.
For the
Inverse Logic
type, the opposite behavior applies. If the input signal is ON, the state turns 0
and if the input signal is OFF, the state turns 1.
Setting the Input to
Latched Logic
, the input state is toggled between 1 and 0 every time the input
signal of the respective digital input changes from OFF to ON.
In
Inverse Latched Logic
mode, the opposite behavior applies. The input state toggles between 1
and 0 every time the input signal changes from ON to OFF.
