4.2.3 Sequential Function Chart (SFC)...

The Sequential Function Chart (SFC) is a graphically oriented language which makes it

possible to describe the chronological order of different actions within a program. For

this the actions are assigned to step elements and the sequence of processing is

controlled by transition elements.

Example for a network in the Sequential Function Chart

Step

A POU written in a Sequential Function Chart consists of a series of steps which are

connected with each other through directed connections (transitions).

There are two types of steps.

The simplified type consists of an action and a flag which shows if the step is active. If

the action of a step is implemented, then a small triangle appears in upper right

corner of the step.

An IEC step consists of a flag and one or more assigned actions or boolean variables.

The associated actions appear to the right of the step.
