Functional Block Diagram (FBD) is a simple and graphical method to program multiple functions in PLC. It is similar to the Ladder Logic diagram except the function block replaces the interconnection of contacts and the coils. You will get to know theFunction Block Diagram (FBD) programming language and use it to program a function block (FB1) and an organization block (OB1). To do this, we will add two constants and ensure they are equal to turn on the LED. In this sense, the term "functional" differs from its use in functional programming or mathematics, where the terms "functional" and "flow" would be confusing. A FBD program is built using function blocks connected together to define the data exchange. This video describes the basics of Function Block Diagrams aka FBDs and relate these diagrams with the ladder logic diagrams.
