Sequential function chart plc. Sequential Function Chart (SFC) is a game-changing tool for designing clear, maintainable, and scalable control systems. It is one of the five languages defined by IEC 61131-3 standard. Additional elements in the chart can determine where the flow of the chart will lead. Sequential function chart (SFC) is a visual programming language used for programmable logic controllers (PLCs). What makes Sequential Function Charts so suited for sequence type logic, is that it uses steps and transitions to perform the instructions. It enables automation professionals to build process logic that’s intuitive, testable, and easy to commission—even in the most complex state-driven systems. This programming language is partic-ularly useful whenever program steps and defined transitions to the individual steps are needed. Aug 28, 2025 · SFC offers a predictable, transparent, and easy-to-troubleshoot language, and a visual way to program complex sequential tasks into a PLC. The sequential function chart a graphically oriented language which makes it possible to describe the chronological order of different actions within a program. Sep 4, 2022 · Sequential Function Chart (SFC) is a graphical programming language among the languages identified by IEC 61131-3 programming languages and standard for PLC programming using ladder logic. di ke4gu 4ahi1a7 aonxn 2yw 3hqwb 7us qxl my 1z29
