Start signal event

A signal start event starts a process instance using a named signal. The signal is fired from a process instance using the intermediary signal throw event (or programmatically through the java or REST API). In both cases, a process instance for any process definitions that have a signal start event with the same name are started. You can select a synchronous or asynchronous start of the process instances.

A signal start event is visualized as a circle with a triangle inside. The triangle is white inside.
