Command: Order by Data Flow

Function: The command numbers the elements in the program by data flow, or in the case of multiple networks by their topological position in the editor.

Call: CFC → Execution Order menu, Execution Order in the context menu

Requirements: A CFC editor is active and the Explicit Execution Order Mode property is selected.

The command is also available when no element is selected.

The order of execution order is determined by the data flow. When there are multiple networks, the order of execution is determined by the topological position of the networks. All numbered elements of the POU are set accordingly. Afterwards, the execution order is identical to that in auto data flow mode. The topological positions of the elements are retained anyway.
