The Counter block counts the number of entities that pass through it. If the OutCount value port has any connections to it, the Counter block pushes its count value to the port every time it changes.
After an entity enters the Counter block, the block determines whether any block downstream of the Counter block’s OutEntity port can accept the entity before pushing the entity out the OutEntity port. If this acceptance fails, the entity is either pushed out the OutBalk port or destroyed if there are no connections to the OutBalk port.
