13.13 SFC Editor
The SFC Editor, provided by the 'SFC Editor' plug-in, is available for programming
objects in the IEC 61131-3 programming language Sequential Function Chart (SFC).
The language is to be chosen when adding a new POU object to the project via the 'Add
Object' command.
The SFC Editor is a graphical editor. General settings concerning behaviour and display
are done in the SFC editor options dialog.
The SFC editor is available in the lower part of the window which opens when you edit
a SFC POU object. In its upper part this window contains the Declaration Editor.
Abb. 399 SFC Editor
The elements used in a SFC diagram by default are available in the "SFC" menu, which
by default is available as soon as the SFC Editor is active. They are to be arranged in a
sequence resp. in parallel sequences of steps which are connected by transitions. See
also: Working in the SFC Editor.
The properties of steps can be edited in a separate Properties box. Inter alia there the
minimum and maximum time of activity can be defined for each step.
Implicit variables can be accessed for controlling the processing of a SFC (for example
step status, timeout analyzation, reset etc.).
The commands for working in the SFC Editor can be called from the context menu or
from the "SFC" menu which by default is available as soon as the SFC Editor is active.
