Active State Data

Output self, child, or leaf active state data to monitor chart activity

Stateflow® can create output and local data to represent the current active state during simulation. Use active state output data to drive Simulink® subsystems. Log active state data for diagnostics.

Topics

Model An Intersection Of One-Way Streets

Models an intersection of one-way roads controlled by a Stateflow® traffic light system. The Stateflow chart tracks the state of each traffic light by using active state output. The behavior of the traffic lights is controlled by parameters on the Stateflow mask.
