A combined editor is available for editing POUs in the languages FBD (function block diagram), LD (ladder diagram), and IL (instruction list).
Activate the IL implementation language for EcoStruxure Machine Expert in the Tools > Options dialog box, category FBD, LD and IL editor, tab IL.
Therefore, a common set of commands and elements is used and an automatic internal conversion between the three languages is done. In offline mode, the programmer can switch between editor views (View).
Keep in mind that there are some special elements which cannot be converted and thus will only be displayed in the appropriate language. Also, there are some constructs which cannot be converted unambiguously between IL and FBD and therefore will be normalized at a conversion back to FBD; specifically, negation of expressions and explicit/implicit output assignments.
You can define the behavior, look, and menus of the FBD/LD/IL editor in the Customize and Options dialog boxes. You also have options to define the display of comments and addresses.
The editor opens in a bipartite window. When you edit an object programmed in FBD/LD/IL, the upper part contains a declaration editor, the lower part contains a coding area.
The programming language for a new object is specified when you create the object.
