1 LabVIEW Advanced for 7.0 Manual Course Errata Exercise 1-4, page 1-24: On faster machines the VI profiler reports incorrect data. It shows that the VI plotting 1 point at a time is faster then the VI plotting 50 points at a time. This is the wrong way round. You should increase the input to the For Loop that generates the data to 10,000 to ensure the VI profiler reports correctly. Exercise 1-6, page 1-35: The block diagram shown here uses a Write to Spreadsheet File VI to write the data to file. In this case, it is more appropriate to open and close the file resources outside of the loop. Exercise 2-3, page 2-22: In step 2, the Set Occurrence should be in the True Case. Alternatively, inverse logic could be used and the while loop conditional set to Continue If True. Exercise 2-4, page 2-26: In step 4, the semaphore subvis will not open until the Semaphore with SubVIs.vi is run. Page 4-25: The bottom figure shows one server used in the block diagram, but the illustration above the block diagram implies that two servers are used. The illustration should show only one server used. Exercise 5-1, page 5-11: The instructions below the front panel are meant to describe the operation of the VI. Do not follow these instructions until after you have finished building the VI.

2 LabVIEW Advanced for 7.0 Manual Course Errata Exercise 5-2, page 5-20: The default path in the VI to execute control is correct in the course manual, but not in the exercise itself. Exercise 6-1, page 6-13: The path on the Complete pathname to Excel file control should be C:\Exercises\LabVIEW Advanced\sine.xls. In step 1a, select the Microsoft Excel Object Library. The Microsoft Excel 10.0 Object Library version 1.4 ships with Microsoft Excel XP. In step 2b, after placing the Property Node, wire the Automation Refnum from the Automation Open to the reference input of the Property Node. Then, expand the node and select the properties. Exercise 6-3, page 6-21: Step 2c refers to the previous figure to complete the contents of the interior True case. However, the False case is displayed. Until this can be repaired, refer to the solution of this VI to view the contents of the True case. Instructor suggestion: show the solution on the overhead while students are completing this exercise. Exercise 6-4, page 6-26: In step 2, your computer may not prompt you to enable macros if they are already enabled. If you are not prompted, check the security setting for macros in Tools» Options» Security» Macro Security is set to Medium or Low. If the security is set to High, Excel will not run any macros and this exercise can not be run. Lesson 7: Event Driven Programming Exercise 7-1, page 7-10: In step 3, label each Boolean button the same as the Boolean text on the button. In step 6c, add the Enhanced Acquire Data VI, not the Acquire Data.vi. Also, the picture below this step looks as iff the Boolean wire comes out of OldVal of the Event Data. It actually begins at the terminal on the Event structure to the left of OldVal.

3 LabVIEW Advanced for 7.0 Slides Course Errata Many slides refer to the wrong page in the course manual for starting an exercise. Slide 1: Slide 1: none. Slide 10: The VIs on this slide should show DataSocket Open and DataSocket Close VIs. Slide 9: The Invoke Node and Register Event Callback are pointed to the wrong nodes. Invoke Node is on the bottom left and Register Event Callback is on the bottom right. Lesson 7: Event-Driven Programming

4 LabVIEW Advanced for 7.0 Exercises/Solutions Course Errata Exercise 1-1, page 1-7: SubVI 1 and SubVI 2 are not exactly identical. In SubVI 2, automatic error handling is enabled and in SubVI 1 it is not. However, enabling or disabling automatic error handling in both subvis does not seem to greatly effect the results of the exercise. Exercise 1-4, page 1-24: On faster machines the VI profiler reports incorrect data. It shows that the VI plotting 1 point at a time is faster then the VI plotting 50 points at a time. This is the wrong way round. You should increase the input to the For Loop that generates the data to 10,000 to ensure the VI profiler reports correctly. Exercise 2-3, page 2-22: On step 2 of the exercise the block diagram that is shown is incorrect. The case statement in the while loop should have the set occurrence in the true condition rather than the false condition. Exercise 5-2, page 5-20: The default path in the VI to execute control is correct in the course manual, but not in the exercise itself. This is true of the solution as well. Exercise 6-1, page 6-13: The default path in the Complete pathname to Excel File control should be C:\Exercises\LabVIEW Advanced\sine.xls in both the exercise and solution. The solution contains an extra Automation Refnum. This does not affect the running of the VI.

5 LabVIEW Advanced for 7.0 Exercises/Solutions Course Errata Lesson 7: Event Driven Programming Exercise 7-1, page 7-14: On step 6c of this exercise it should read Enhanced Acquire Data VI rather than just Acquire Data VI. In the block diagram below step 6c the Enhanced Acquire Data VI should be shown rather than the Acquire Data VI. Also the Event Data Node, in the block diagram shown, is covering up the wires that are connected to the tunnels on the left side of the event structure giving the appearance that they are actually connected to OldVal and Type.
