Function
The output sends when the input receives a value that is not blocked.
If the None option is selected for the Blocked Value parameter, the filter element forwards all values
received.
Application examples
• A presence detector sends 1-bit values. After a defined time it sends the value 0 to switch off the light.
Other appliances are not to react to this value 0 because they have their own timer control.
• A push-button or a key card triggers the sending of 1-bit values, 1 or 0. The two values are to trigger
different actions.
• The staircase lighting will switch off after receiving the value 0. If this action is not required, the value 0
can be blocked by a filter.
Other
Inputs not connected are treated as if they did not exist.
