Creating or editing initial steps or steps in FBD

How to create initial steps or →steps in the →graphical FBD-editor:

1. From the context menu of the FBD-editor, select Create and select one of the following commands:

   1. Initial Step to create an initial step – Alternative: Press Ctrl+Shift+F, I.

   2. Step to create a step – Alternative: Press Ctrl+Shift+F, S.

2. Position the initial step or step where you need it.
   During this user action, it is possible that affected lines are automatically rerouted. If the positioned element is presented with a red rectangle, the destination is not possible.
   You might want to use the following key while positioning the element: Press the ESC-key, if you do not want to position the element and abort the action.
   All following descriptions are valid for the initial step as well as for the step, even if only the expression "step" is used.

3. Press the primary mouse button or the Enter-key to create the step.
   If the step is highlighted as faulty, the new name is causing an error. Enter another name or correct the other FBD-logic until the FBD-object does not contain any faulty FBD-elements.

How to change the name of a step:

1. Double-click a step and enter the new (unique) name. The name must be an →IEC-identifier.

2. Press the Enter-key or click anywhere outside the element so that the new name is entered. Press the ESC-key, if you want to discard the new name.
   If the elements are highlighted as faulty, the new name is causing an error. Enter another name or correct the other FBD-logic until the FBD-object does not contain any faulty FBD-elements.
