FUNCTION BLOCK DIAGRAM SYMBOLS
Functional block diagram - Wikipedia
The block diagram can use additional schematic symbols to show particular properties. Functional block diagrams have been used in a wide range applications, from systems engineering to software engineering , since the late 1950s.
Function Block Diagram - an overview | ScienceDirect Topics
The boxes in the function block diagram depicted in Figure 2 represent program activities, while lines model unidirectional flow (from left to right) of the type of information necessary for the function blocks to carry out these activities. Individual function blocks are invoked according to the partial ordering given by the “wiring” and, in the course of this, they pass data along their connecting lines.
Functional Block Diagram
A functional block diagram as one of the types of existing block diagrams can be used for describing the functions and relationships between different elements within one particular system. Such functional block diagram can be used for illustrating the functions of one system using blocks to represent the elements of this system.

The term function block diagram (FBD) is used for PLC programs described in terms of graphical blocks. It is described as a graphical language for depicting signal and data flows through blocks, which are reusable software elements. A function block is a program instruction unit that, when executed, yields one or more output values.[PDF]

Symbols Used in Block Diagrams. When block diagrams are used in electrical engineering, the arrows connecting components represent the direction of signal flow through the system. Whatever any specific block represents should be written on the inside of that block. A block diagram can also be drawn in increasing detail if analysis requires it.
Functional flow block diagram - Wikipedia
Development of functional flow block diagrams. Note that the diagram shows both input (transfer to operational orbit) and output (transfer to space transportation system orbit), thus initiating the interface identification and control process. Each block in the second level diagram can be progressively developed into a series of functions, as shown in the third level diagram on Figure 2.
