SFC (Sequential Function Chart) is a visual structured graphical language that utilizes PLC (Programmable Logic Controller) to organize application programs using flowcharts based on the processing order. SFC divides the application program into two main components: 'Steps' and 'Transitions,' providing a method to link them. Each 'Step' is associated with a specific 'Action', while each 'Transition' is connected to a 'Transition Condition.'
We will program our first Sequential Function Chart (SFC) in our LS Electric XGB PLC. SFC programming is commonly used in industries such as manufacturing, automotive, and process control, where complex sequences of operations need to be coordinated. It allows the programmer to visually organize the control logic, making it easier to design, understand, and maintain the control system (Troubleshooting.) SFC programming is beneficial for applications with many interrelated components and where the sequence of operations is critical to the system's overall functioning.
This post will explore the fundamentals of programming an XGB PLC using Sequential Function Chart programming. We will be programming our lighted pushbuttons to control a start-stop circuit. This will show the basics of this IEC programming language. Let's get started.
