A SignalEvent represents the receipt of an asynchronous Signal instance.

Unified Modeling Language 2.5.1

A MessageEvent specifies the receipt by an object of either an Operation call or a Signal instance.

When Monitor Traction is enabled, it begins listening for signals coming in from the wheel and accelerometer, as indicated by the signal receipt symbols on the left, which begin listening automatically when the activity is enabled.

To get synchronisation of multiple AcceptEventAction "loops" to work in Cameo Simulation Toolkit one sometimes needs an additional ForkNode

If it has isUnmarshall=true, then it must have result OutputPins corresponding to each of the attributes of the Signal of the SignalEvent (in order), and the attribute values of the Signal instance associated with an accepted SignalEvent occurrence ...

Source

Unified Modeling Language 2.5.1

If an accept signal action has isUnmarshall=false, then it must have a single result OutputPin on which the Signal instance associated with an accepted SignalEvent occurrence is placed.

Source

Unified Modeling Language 2.5.1

An AcceptEventAction with a trigger for a SignalEvent is informally called an accept signal action.

Unified Modeling Language 2.5.1

Cameo Simulation Toolkit DOES NOT leverage a Reception on a Class/Block at all! Use an AcceptEventAction with a SignalEvent trigger or an 'effect' on a Transition instead. There is a formal fUML restriction that a Reception should not have a method.
