Command: Insert Action Association
Symbol: 
Function: The command assigns an IEC action to a step.
Call: SFC menu
Requirement: A step is selected.
CODESYS inserts the action element to the right of the selected step element.
If you have already assigned one or more actions to the step, then they are displayed in an action list.
If you have selected the step element, then as the first action of the step – at first position of the action list.
If you have selected one of the available actions in the action list, then directly before – above the action.
The left section of the action element includes the N qualifier by default. You enter the action name in the right section. To do this, click in the box to get an editing frame. You need to have already created this action as a POU in the project.
You can also edit the qualifier.
