CLD Practice Exam Review (Object Oriented Version)

I did the CLD sprinkler controller sample exam using objects. There are no plain subvis that are not part of a class.

 

Can someone comment and offer feedback?

Time-

 

Really, very nicely done!  Of course, a few hits-

 

I do not see how the "program" halts when entering "set-up" mode.  having just looked at it I may have missed something but, there are no comments to aid my inspection of this req. 

 

 


 

Clicking the Setup button during a run should immediately stop the controller and activate the Zone Setup array.

 


 

Whoops- I mis-spoke!  OK the VI info documents the function!  the lack of a "stop" method hurts a bit when there is a detailed start method. 

 

Generally the vi's are cleanly wired but this is unanticipated--

You would take a style hit for those wires. 

 

The Hierarchy view is bit too deep for the requirements. 

 

the main vi's icon is inconsistant.

 

OK - enough bad stuff-  Nicely done!  take the exam!

Thanks for looking at it!

 

You are right. An explicit stop method would probably be clearer.

 

I noticed the wires after I posted. It wasn't like that when I wrote it - really! What happened is that the bundle by name got wider when I renamed the properties by adding the units (Seconds). I will have to make sure not to do any renaming after the fact. As for the inconsistant main vi icon you are right. I probably should have given it a banner. But it is the only thing not part of the class so it would have to be a different color.

 

Another thing I neglected to do was to give the timer and controller classes distinctive wire apearances.

 

Thanks again. Now if I could do this in under four hours I will be fine. Well I could do the sprinkler controller in under four hours but who knows what NI will throw at me.
