7.5 Function block diagram editor

The function block diagram editor is a graphic editor that uses a list of networks.

Each network contains a structure that each represents a logical or arithmetic expression, a function

block call, a function, a program, a jump or a Return instruction.

Tip!

The most essential FBD editor commands are also available in the shortcut menu

(right mouse key or <Ctrl>+<F10>)

7.5.1 Cursor positions in FBD

Every piece of text represents a possible cursor position. The selected text is highlighted in blue and

can now be changed.

Otherwise the current cursor position is identified with a dotted rectangle. All the possible cursor

positions are listed below together with an example:

Every text box (possible cursor positions identified with a f rame)

Every input

Every organization unit

Outputs if followed by an assignment or jump

The intersection upon an assignment, jump or Return instruction

The intersection directly before an assignment

Behind the last (right-hand) object of a network (”last cursor position”)
