Halt

Library

Events

Description

This block has a unique input event port. Upon the arrival of an event, the simulation is stopped and the main Scicos window is activated. Simulation can be restarted or continued (Run button).

State on halt	0

• State on halt: A scalar value to be placed in the state of the block. For debugging purposes this allows to distinguish between different halts.
