In some regions and within some companies, you will find that the terms SFC and GRAFCET are used interchangeably. Like other IEC-based languages, it can share commonIEC elements and reference tags, as well as objects created in other languages, with your Logix program. SFC is a powerful, high-level language, similar to Function Block Diagram. Often, you can create the equivalent functionality of 40 Ladder Logic rungs in a few SFC steps. An SFC routine (again like Function Block) will typically have more computational overhead than the same routine developed using low-level languages such as ladder logic or structured text. SFC routines are very easy to debug and maintain because of their compact visual design. SFC has its strengths...
