ActivatedEdge

Activated Edge is similar to Edge but generates events only when activated

ActivatedEdge

Library

StateMachine

Description

This block is used for detecting zero crossings. Optionally, the previous input value can be set to have full control over the first activation of the block. For example if a state must exit if the input of the block is larger than zero, then simply detecting a zero-crossing to initiate an exit may not be enough: when entering the state, the value of the input may already be larger than zero. This could happen in particular at initial time. By setting the previous input value to 0, a zero-crossing is detected and the state is exited.
