What programming paradigm is followed by Function Block Diagram (FBD)?

Function Block Diagram (FBD) follows the data flow programming paradigm. In this context, FBD allows the user to create programs that visually represent the flow of data between function blocks. Each block performs a specific function and is interconnected with lines that signify data flow. This visual representation helps in understanding how signals move and are processed through various functions, making the data flow aspect central to its design.

In FBD, functions are treated as components that accept inputs, perform calculations or operations, and produce outputs, which then may be further processed by other blocks. This characteristic aligns closely with data flow programming, where the primary focus is on the flow of information rather than the sequence of execution as found in procedural programming or the organization of data in object-oriented programming.

Therefore, recognizing FBD as a data flow programming approach emphasizes its unique capability to represent operations modularly while highlighting the relationships and interactions between different functions instead of detailing the control flow or procedures.
