 \section{Abstract}
 Sequential Function Chart (SFC) describes the behaviour of a control program. It is derived from Petri Nets and GRAFCET. This package contains a set of symbols that simplifies the drawing of SFC diagrams with emphasis in readability and in agreement with the international standard IEC~61\,131-3. It extends the \tikzname-library |circuits| which defines general keys for creating circuits. All graphic elements of SFC are supported by |tikz-sfc|: steps (normal and initial), transitions, actions and actions qualifiers (with and without time duration) are supported. The placement of all actions associated with a step is done automatically. Comments can also be placed automatically in a suitable location near the element they refer to. The final appearance of each element can be fine-tuned individually or in group.

 IEC~61\,131-3 Sequential Function Chart (SFC) describes the behaviour of a control program. It is derived from Petri Nets and IEC~60\,848 GRAFCET, with the changes necessary to convert the representation from a documentation standard to a set of execution control elements.

GRAFCET is regarded as a \emph{specification language} and SFC as an \emph{implementations of the language for programming}. Many features of GRAFCET are not supported in SFC, but all GRAFCET functionalities can be implemented in SFC, although not directly. Particularly, assignation condition, time dependent assignation condition, delayed action, time limited action, stored actions, action on activation, action on deactivation, action at the clearing and action on event are all done, one way or another, in SFC using action qualifiers\footnote{This package typesets qualifiers in the agreement with the international standard IEC 61 131-3/2013.  The lack of qualifier support in GRAFCET and in particular in the |grafcet| package is the main reason to have a different package for SFC.} (mainly). Consequently, the graphical representation of those features is fairly different. If you are interested in GRAFCET, refer to Robert Papanicola's |grafcet| package\footnote{The |grafcet| package uses a very different approach in the user interface. It is based in writing down a sequence of macro calls. The |tikz-sfc| uses the \tikzname-library |circuits| interface in which you place symbols along a path.}.

 This section brings some recommendations that reflect the way I produce SFC diagrams. It may or may not work for you. Feel free to e-mail me if you have better ideas.
 
-The first thing to consider is that |tikz-sfc| uses the |\tikzcircuitssizeunit| to keep all figures proportional. Therefore, when you consider any dimension related to symbol size it is good idea to set that dimension in respect to |\tikzcircuitssizeunit|, i.e., using |\tikzcircuitssizeunit| as the unit of length. The default value of |\tikzcircuitssizeunit| is 7\,pt or approximately 2.46\,mm and it can be set by the |circuit symbol unit| key among several other keys.
+The first thing to consider is that, as the manual says, ``\tikzname\ \emph{ist kein Zeichenprogramm}'' which translates to ``\tikzname\ \emph{is not a drawing program}''. You shall start with a draft of you chart and then codify it using \tikzname. Generally, a handmade pencil sketch will do. In this draft, you shall use node names for future reference.

 Steps and transitions are placed along a vertical line. An even space between them are desired. The |to| command is used to interrupt the line and place the symbol between two coordinates. Since a transition is only and horizontal line crossing the vertical line, it does not matter if the vertical line is interrupted or not. Thus, it is possible to employ the command |node| to place a transition. In this way, the transition centre coordinates will be precisely known, but the centre coordinates of the step will be in the middle point of two known points. For a single sequence, it makes sense to place all transitions and then connect them with evenly spaced steps. This is rarely the case, however. Commonly, it is necessary to place an initial step in the begin of a line and dummy nodes (coordinate point) for loops.

 \section{Known Issues}
-The user interface is a bit inconsistent: texts are treated differently depending on where they should appear. Normally, |info| and |info'| keys are used to place text on the chart, but sometimes actions need one or two extra text (qualifier and time duration) and it is done by to other keys, namely, |qualifier| and |time|. The problem is that these keys do not accept optional arguments like |info| and |info'|. It is possible to modify those keys to deal with optional arguments, but there is price to pay.

-The keys |info| and |info'|, largely employ to place text, actually uses the |label| interface. This is great because you can pass an optional list of configurations. The tread out is that you have to be careful when writing the text, particularly you need to surround the commas, colons\footnote{If you literaly mean ``:'' and not a \meta{angle} specification.} and equal signs in curly brackets. This is due to |\pgfkeys|.

+\section*{Appendix A -- Beamer example of delta-star motor starter with dead time in SFC}
+
+In this example, the animation is done in two layers: the chart is drawn on foreground with step, transitions, actions and animation (filling and colouring); on the background, circles (actually, ellipses since |x| and |y| scales are different) are drawn in light red to highlight the activated transition. In order to place the ellipses in the precise position, every transition is named.
+
+At first, only the SFC is drawn and the example of Section~\ref{sec:introduction} is used as starting point. Since the fonts used in the beamer presentation are different in size, it is necessary the adjust the chart size. In this particular, |sfcaqw| was increased to |9\tikzcircuitssizeunit|. When the chart is done, the animation part is made adding the |visible| key in the foreground and the |\visible| macro in the background.
+
+Macro |\overlaynumber|, placed in the |frame| title, is used in the development phase to show the slide number in a sequence (animation). It helps the development of animated slides because you can see the slide number to be used with |visible| and |alt| keys or |\visible| and |\alt| macros.
