Set Start of Feedback

Overview

The CFC > Set Start of Feedback command is available when a CFC editor is active and the Auto Data Flow Mode option is activated in the CFC Execution Order tab of the Properties dialog box. Additionally, an element of a feedback that is included in a network of a CFC POU must be selected.

Execute the command to define the selected element as the starting point within a network with feedback. The starting point within a feedback is flagged with a symbol in the CFC editor. This element is assigned the lowest number in the execution order within the feedback. At runtime, the processing of the feedback starts with this element.

Example

In the example, the Set Start of Feedback command was executed on FB2_0 as indicated by the symbol and the execution order 0.
