In digital mode, the input signal level (0 or 1) is measured. Such an input can be used for logic
sensors, the readings of which are determined by two states (on/off).
In the frequency mode, the frequency of the pulse signal is measured. Such an input, for example, is
convenient to use for a car tachometer.
In pulse mode, the number of pulses at the input is counted. Such an input can be used for flow rate
sensors, for example, fuel consumption.
In the settings of
multifunctional inputs in the “Configurator” program, in add
ition to selecting a
mode for each input, there is a parameter called “Active Level”. It can take the value “low” and “high” and
characterizes the magnitude and direction of the input tightening.
