I am pleased to have successfully achieved Certified LabVIEW Architect status which is the highest-level qualification with National Instruments platform and LabVIEW programming language. I passed exam on my first attempt. I chose standard Module/API based architecture that I intend to implement in most of my labview projects. It is very neat architecture and easily scales. The architecture also helped...
Labview Error Handling
Labview vi when programmed neatly with error terminals could be a good repeatable code. Any new applications for vi would successfully pass error out to the error out terminals of the vi which means developers find bugs by only monitoring inputs and outputs of the vi without requiring to look deep into the code. Here is an...
Compact RIO Controllers
Composition of CRIO PAC
Compact RIO is industrial ruggedized Programmable Automation Controller PAC that provides interface to C Series Module for I/O connectivity. Certain models carry Field Programmable Gate Array in the back plate chassis. A full Compact RIO PAC controller could be a combination of and FPGA Chassis with hot-swappable C Series modules and a pluggable real...
Data Acquisition Systems Applications of data acquisition system
Data acquisition systems are required to test products prior being used in service or by public. Many products are required to be subjected to extreme conditions to ensure the product would still be operational and not detrimental to environment. For instance, air craft motor drive must be tested under same atmospheric condition that...
Programming using DAQ functions
DAQ devices
Many National instrument devices such as PXI, SCXI, PCI/PCIe, USB use NI DAQmx drivers and library functions within labview to achieve data acquisition and generation. The most common I/O is Digital Inputs, Digital Outputs, Analogue Inputs, Analogue Outputs and Counter channels. In this article, I would briefly go through some of the good practices that...
