Error handling within an aggregation block

To handle an error condition within an aggregation block a Stop or Fail mediation primitive can be used. Alternatively, you can wire to the Stop input terminal of the Fan In mediation primitive.

The Fan In mediation primitive includes a property that specifies the timeout value. The timeout period starts when the associated Fan Out mediation primitive fires an output terminal for the first time. If a message arrives at the Fan In mediation primitive in terminal after this timeout period, it is considered late, and the incomplete terminal is fired. The default value for the timeout property is -1, which means there is no timeout, and no messages are considered late.
