NI CLAD Exam Topics :
| Section | Weight | Objectives |
|---|---|---|
| Hardware | 10% | • Connecting Hardware: Sensors, DAQ, Devices under test (DUT. • Acquiring and validating a signal • Processing signals • Using appropriate sample rates |
| LabVIEW Programming Environment | 25% | • Setting up and using a LabVIEW Project to: o Add, delete, and move elements o Use libraries and appropriate types of folders o Avoid cross-linking • Data Types: o Recognize data types on the front panel o Recognize data types on the block diagram from terminals and wires o Choose appropriate controls, indicators, data types, & functions for a given scenario • Predicting order-of-execution and behavior of o A non-looping VI o A Simple State Machine o An Event-driven UI Handler o Parallel Loops (without queues) • Using basic functions to create a simple Acquire-Analyze-Visualize application • Troubleshooting by identifying and correcting the cause of a broken arrow or incorrect data • Error handling using error clusters and merge error functions to ensure errors are handled well • Navigating LabVIEW help to get more information about inputs, outputs, and functions |
| LabVIEW Programming Fundamentals | 50% | • Loops o Create continuous HW acquisition or generation loop by applying a Open-Configure-Perform Operation-Close model. o Retain data in shift registers o Use input and output terminals effectively, including: ? Determining the last value output ? Indexing input and output terminals ? Concatenating output ? Using conditional output ? Using shift registers, both initialized and uninitialized. o Use timing of loops appropriately, including: ? Software timing ? Hardware timing o Use For Loops and While Loops appropriately • Arrays o View data from an n-channel HW acquisition VI (using the DAQmx Read VI) using a waveform graph, waveform chart, or numeric/waveform array indicator. o Extract a single channel of data (waveform or 1D Array) from a: ? 1D waveform array representing acquired data from multiple channels ? 2D numeric array representing acquired data from multiple channels ? 1D numeric array representing single measurement from multiple channels o Use a For Loop with auto-indexing and conditional tunnels to: ? Iterate through an array ? Iterate processing code on each channel of data in a 1D waveform array ? Generate an array of data that meets required conditions o Identify by sight and be able to use and predict the behavior of the following array functions and VIs: ? Array Size ? Index Array ? Replace Subset ? Insert Into Array ? Delete From Array ? Initialize Array ? Build Array ? Array Subset ? Max & Min ? Sort 1D Array ? Search 1D Array ? Split 1D Array • Writing conditional code to perform an action based on the value of a user input or a measurement result. • Reading and Writing data to a file o Use Open/Act/Close model for file I/O o Write data to a text file using high-level file I/O functions o Continuously stream data to a text file or a TDMS file o Append data to an existing data file o Log data using simple VIs o Acquire data from DAQmx functions o Display data on a graph o Save data to a CSV file o Choose single measurement/multiple channel and single channel/multiple measurements configurations appropriately |
| Programming Best Practices | 15% | • SubVIs – Reusing Code o Create SubVIs to increase readability and scalability of VIs o Configure the subVI connector pane using best practices o Choose appropriate code as a SubVI source • Clusters – Grouping Data of Mixed Data Types o Create, manipulate, analyze, and use cluster data in common scenarios o Group related data by creating a cluster to improve data organization and VI readability • Type Defs – Propagate Data Type Changes o Create Type Defs and use Type Defs in multiple places o Update Type Defs to propagate changes to all instances of the Type Def |
