7.5.7 The Function Block Diagram Editor...
This is how a POU written in the FBD under the corresponding PLC Designer editor
looks:
The Function Block Diagram editor is a graphic editor. It works with a list of networks,
in which every network contains a structure that displays, respectively, a logical or an
arithmetical expression, the calling up of a function block, a function, a program, a
jump, or a return instruction. The most important commands are found in the context
menu (right mouse button or <Ctrl>+<F10>).
Regard the possibility to switch the display of a FUP-POU between FUP- and KOP
editor, in offline mode as well as in online mode. Also regard the possibilities given by
the options dialog.
