2. Filtering Overview Debounce The configurable filtering is done in 2 stages debounce and chatter removal A CAUTION Danger of incorrect interpretation of the input data Filters are used to suppress the input recognition in a defined way Filtering should only be used in a suitable way to prevent too much or undesired suppression of input data Failure to follow this instruction can result in injury or equipment damage Debouncing can be used on all input functions and prevents the processing of fast state changes of the inputs like for example those caused by contact bouncing Signal changes are ignored depending on the filter type and the preset time The value range for the filter time is O to 255 ms the value O deactivated the debounce filter The selection of the debounce filter type stable signal or integrating affects all 8 function block inputs e Stable Signal Filtering A signal change is only registered if the polarity change stays stable for longer than the filter time each new change resets the filter time e Integrating Filtering A signal change is only registered if the time integral of the input signal reaches the programmed filter time taking any polarity change into account Note Debounce Time gt 1 ms is recommended to ensure enough immunity against electromagnetic disturbances This means that input signal states gt 2 ms and events up to 250 Hz can be processed In non
