 It is possible to limits received event notifications into minimum and maximum boundaries as well as doing frequency thinning. This is possible using the argument filter with one or more of the filters available :
 
-* frequency: specify in Hertz the frequency which will be used to getting notified of new CAN events for the designated signal. If, during the blocked time, further changed CAN messages are received, the last valid one will be transferred after the lockout with a RX_CHANGED.

 * min: Minimum value that the decoded value needs to be above to get pushed to the subscribed client(s).
 * max: Maximum value that the decoded value needs to be below to get pushed to the subscribed client(s)
