SFCs are one of the five PLC programming languages defined by the IEC 61131-3 standard, along with ladder logic, function block diagram, structured text, and instruction list.

These environments typically combine all the previously mentioned programming methods—ladder logic, function blocks, structured text, and sequential function charts—into one platform.

However, SFC as defined in the IEC-1131 standard is not intended to be a complete programming language. Rather, it is a way of organizing the sequential activity of ladder logic programs.

Setup the PLC Programming Environment: Connect the PLC to the computer system and launch the PLC programming software. Ensure all input and output devices are correctly connected to the PLC’s I/O ...

This paper analyses the use of two control software design methodologies for developing a solution to control an automated manufacturing cell. Two separate approaches, sequential function charts and ...

Also known as "combinatorial logic," it refers to a digital logic function made of primitive logic gates (AND, OR, NOT, etc.) in which all outputs of the function are directly related to the ...
