35. Section II What is a subVI? Creating a subVI Using a VI as a subVI

36. SubVIs LabVIEW is modular Any VI can be used as a subroutine (or subVI) to other programs Advantages –Modular –Easier to debug –Don’t have to recreate code

37. Creating a SubVI 1.Create code 2.Select code for use in subVI 3.Click Edit-Create subVI

38. Editing a SubVI

39. Insert the SubVI into a Top Level VI Accessing user-made subVIs Functions >> Select a VI Or Drag icon onto target diagram

40. Create SubVI from your code

41. View your subVI

42. Section III – Data Acquisition Data acquisition (DAQ) basics Connecting Signals Simple DAQ application

51. Section IV – Loops and Charts For Loop While Loop Charts Graphs

52. Loops While Loops –Terminated by condition –Always Runs Once –Delay between iterations may be added For Loops –Terminate after N iterations –N specified on block diagram

53. Loops (cont.) While Loop 1.Select the loop 2.Enclose Code to Repeat

54. Charts and Graphs Waveform Charts display a history of values over time - Strip Chart (continuous scrolling) - Scope Chart (repeatedly redraws over the same region) - Sweep Chart (redraws curve to the right of the old curve) Waveform Graphs and X-Y Graphs - Wavefrom Graphs plot Y for regular increments of X - X-Y Graphs plot Y vs. X for any X-Y sets (non-regular)

55. Charts Waveform chart – special numeric indicator that can display a history of values Controls >> Graphs >> Waveform Chart

56. Wiring Data into Charts Single Plot ChartsMultiplot Charts

57. Combining data onto one graph

58. File I/O Using The LVM Express Function

59. File I/O Using Traditional Functions Read/write to spreadsheet file Read/write characters to file (ASCII) Read lines from file Read/write binary file Easy File I/O VIs
