Description
The Counter block implements a counter which is either increasing (from minimum value to maximum value) or decreasing (from upper maximum to minimum value). The counter initial value is a block parameter and increments (or decrements) are specified by the Step parameter.
The block is externally activated: an activation port is placed on the block to connect to an event generator such as an EventClock block.
