Sequential Function Chart (and Grafcet) language can be used to describe the
sequential part of an automation system in simple graphical format using steps and
transitions.
SFC language does not process charts in the same way as Grafcet language:
b
b
Unity Pro software has one editor for these two languages with the option of defining
behavior in the application settings (Tools/Project Settings/Language Extensions
menu).
SFC language is only used in sections belonging to the master task. Each SFC
section consists of a main chart sub-section CHART and sub-sections for each of the
macro-steps. Characteristics of these charts include the following:
b
(used to set up a hierarchical chart structure)
b
b
Associated with steps and transitions respectively, the actions and transition
conditions can be:
b
conditions are defined by a single variable
b
in Ladder, Function Block Diagram, Structured Text or Instruction List language) is
necessary
To check that machine scans have been completed successfully, activity times
(minimum, maximum) can be associated with each step. These times are set by the
user.
For each SFC section, the graphics editor provides a maximum of:
b
jumps need one cell respectively.

To help you to create basic charts, graphic screens can be used to create “n” steps in
series and “m” steps in parallel in a single operation.
Dialog boxes can be used to assign associated properties to steps (activity time,
actions), transitions (variable linked to transition condition), etc.
