In previous releases, reactive ports are signal input ports that listen for updates or changes in the input signal. When the input signal changes, an appropriate reaction occurs in the block possessing the port. Convert all reactive port event signals to messages.
Here is an example of sending a message when data is less than or equal to 0.
Here is an example of sending messages on trigger edges (rising, falling, or either).
Here is an example of sending messages based on value changes (rising, falling, or either).
Here is a list of the reactive ports in SimEvents® blocks and the action you can take for them.
