Overview
The SFC (Sequential Function Chart) language is a graphical programming language
developed to facilitate the description of step progression programs, which mainly
control sequential processes.
SFC, with its graphical representation of step flow and with description of the
conditions for step progression and the actions in each step, allows users to program
the control of sequential processes.

SFC offers the following advantages.
Since step flow and program control correspond, even third-party programmers can
easily understand the program, as a whole. This reduces the program debugging and
maintenance workload.

Programs can be created separately for each step, without the need to consider
complicated requirement exchanges between steps. In other words, each step can be
programmed separately, by a different developer, making program development
simpler and more efficient.
