CH6 使用結構(Structures) For Loop While Loop Iteration terminal Conditional terminal Count terminal Shift register Select function Case Structure Selector terminal Dialog box Wait (ms) Flat Sequence Structure Stacked Sequence Structure Formula Node Expression Node Timed Structure

For Loop For i=0 to N-1 Execute Subdiagram

While Loop Do Execute subdiagram While condition is FALSE (Until condition is TRUE)

While Loop特性

練習6-1 Counting the Loops

Shift Registers(位移暫存器)

A While Loop having one shift register with multiple left terminal elements

(Left) Two separate variables (Left) Two separate variables. (Right) Several loop values of one variable

Shift register and tunnel, two different ways of passing data through the walls of a loop

練習6-2

Two loops showing the difference between shift registers (A) and tunnels(B)
