Figure 279 Apple Bagger, Solution 2
Key Points
Start: Using a Start object for this program is redundant, since
you can use the Run button on the main menu bar. Start is best
used when you have two programs on a screen, and you want to
be able to run them independently. Or you have a program with
a feedback loop, and you want to define where to initiate
execution.
Shift Register: You use a Shift Register to access the previous
values of the output. In solution 2, the Counter is keeping a
running count of every apple before it is weighed, so the count
must be reduced by one when the total weight exceeds 10.
Gate: The Gate is used to hold the output until another action
occurs and activates its sequence pin. Here, when the condition
A<=10 is no longer true, the Else pin on the If/Then/Else object
activates the gate.
