5.5. Filter Age Time
This setting defines the time a filter string, RFID tag, or barcode
will continue to be filtered after the last time it was received. If an
entry is received before the Filter Age Time has passed, the entry
will be filtered and the data will not be sent to the PLC and/or
application. However, if the Filter Age Time has passed, it will pass
filtering and be sent to the PLC and/or application.
Example:
•
The Filter Age Time is set to five seconds:
-
An entry is received for the first time and sent to the PLC and/or application.
-
It is then received again in four seconds. The entry will not be sent to the PLC and/or application since
it is still on the filter list.
-
The entry is then received after another six seconds. The entry will be sent to the PLC and/or
application again since it was removed from the filter list after five seconds.
-
End result = entry is sent to the PLC and/or application twice.
•
The Filter Age Time is then set to ten seconds.
-
An entry is received for the first time and sent to the PLC and/or application.
-
It is then received again in four seconds. The entry will not be sent to the PLC and/or application since
it is still on the filter list.
-
The entry is then received after another six seconds. The entry will not be sent to the PLC and/or
application since it is still on the filter list.
-
End result = entry is sent to the PLC and/or application once.
