Model 5 - Sending Signals to Multiple Process Instances

Goals of this lesson

• Learn how to use signal events

How-to

As in the Message Events in Model 4c all linked Signal Events have to use the same name to identify them as linked. In contrast to messages, signals can be sent to multiple receivers.

Parametrization

• The model and its settings show that the upper process sends a signal every 4 TU.
• The lower process starts every 1 TU.

Explanation

This means, that always 4 instances of the lower process wait for a signal from the upper process, and the incoming signal always re-activates these four process instances of the lower processing pool.
