FBD Language

The Functional Block Diagram (FBD) is a graphic language enabling programmers to build complex procedures by taking existing functions from the standard library, function section, or function block section.

In FBD containers, also include Ladder Diagram (LD) elements like coils, contacts, jumps, labels, and returns. However, in contrast to LD elements usage in LD containers where these elements follow strict graphical positioning regulations, LD elements within FBD container are independent of these regulations.
