求翻译：功能图（FBD: Function Block Diagram ）使用类似于布尔代数的图形逻辑符号来表示控制逻辑，一些复杂的功能用指令框表示，适合于有数字电路基础的编程人员使用。是什么意思？

Function chart (FBD:Function Block Diagram) using graphics similar to the Boolean algebra of logic symbols to represent the control logic, complex functions are represented by instruction box, suitable for Basic programmers use of digital circuits.

Functional map (FBD Function Block Diagram): similar to the use of graphical logic algebra notation for control logic, some complex functions in order to fit the box indicates that there is a digital circuit based programrs use.

Functional diagram (FBD: Function Block Diagram) uses is similar in the Boolean algebra graph logical symbol expressed the control logic, some complex functions indicated with the instruction frame, suits in has the digital circuit foundation programmers to use.
