About Graphical Scenario

A scenario is processed by following the links connecting the building blocks contained within the scenario. It is executed following the flow of the links that connect its elements as follows:

• The starting point of the scenario (Start) is activated.
• All the event links emanating from the Start point are activated and transmit the event flow to all the building blocks to which they are connected.
• Building blocks receiving the flow through their In event become active and are executed.
• After their execution, the building blocks transmit the event flow through the links that emanate from their Out event.
• Step three is repeated until there are no more links emanating from the event output of an active building block.

Graphical scenarios contain a set of graphical elements.

Building Blocks

Building blocks are used to implement behavior tasks and functions. Building blocks are provided with the app and are either:

• Direct bindings of existing API functions
• Made from JavaScript source files

For more information about provided building blocks, see the scenario online help.

Data Ports

Data ports are used to define the data flow. The following data ports are available on building blocks and on local data ports:

	In ports
	Out ports

Control Ports

Control ports are used to define the control flow. The following control ports are available on building blocks, input control ports, or output control ports.

	In and Out ports
	Control In ports
	Control Out ports

Hierarchical scenarios let you define complex scenarios and reuse existing scenarios.

A hierarchy of scenarios is only available through graphical scenario calls.

A Call Scenario block referencing an existing graphical scenario can be inserted in a graphical scenario.
