The command is available when a CFC editor is active and the option is activated in the tab of the dialog box.
Execute the command to temporarily display numbered tags for the CFC elements of the programming object. The numbers represent the execution order that has been assigned automatically. The execution order is determined by data flow. In the case of multiple networks, it is determined by their topological position in the editor.
The tags are hidden as soon as you click in the CFC editor.
