SFC 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 pro-
gression and the actions in each step, allows users to program the control of sequential processes.
Additional Information
For details on SFC programming specifications, notation, and input procedures, refer to the CX-
programmer Operation Manual: SFC Programming (Cat. No. W469).
