Figure 58: Binary input filtering
At the beginning, the input signal is at the high state, the short low state is filtered
and no input state change is detected. The low state starting from the time t
exceeds the filter time, which means that the change in the input state is detected
and the time tag attached to the input change is t
is detected and the time tag t
Each binary input has a filter time parameter
of the binary input of the module in question (for example

When a binary input is inverted, the state of the input is TRUE (1) when no control
voltage is applied to its terminals. Accordingly, the input state is FALSE (0) when a
control voltage is applied to the terminals of the binary input.
