[edit] Function Block Diagram
A Function Block Diagram (FBD) is a diagram, that describes a function between input variables and output variables. A function is described as a set of elementary blocks. Input and output variables are connected to blocks by connection lines. See Category:Function block diagrams

[edit] Functional Flow Block Diagrams
Functional Flow Block Diagrams (FFBD) are multi-tier, time-sequenced, step-by-step flow diagram of the system’s functional flow, see Category:Functional flow block diagrams
