FILTERING A DIGITAL INPUT SIGNAL
A digital input is filtered using a constant level (1 or 0) detection algorithm on the "sensor" signal measured for a certain period of time. If the signal is stable for the entire detection duration, the FILTERED DIGITAL INPUT symbol output takes the value of the signal measured. Otherwise, it remains unchanged. The detection duration can be parameterised. The value (between 1 and 255), which can be adjusted in the parameterisation window of the symbol, is a multiple of the cycle time.
Reminder: The cycle time can be adjusted in a dialogue box, which is opened by clicking on the "PROGRAM" zone in the programming window.
