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...
Labview Data and Memory
In this article, I will briefly go through data storage as memory bits and bytes when programmed using labview code. I particularly like labview when it comes to memory allocation and deallocation. Back in university days, I recall efforts I had to put in C programming language for memory management.
Fortunately, Labview does memory management - allocation...
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...
Multithreading with Labview
Today we execute labview apps on CPU with hyper-threading capabilities and programmer must make every effort possible to achieve maximum task handling, optimisation and prioritisation. In order to further achieve improved reliability and execution time for the tasks, labview is equipped with 5 levels of 'Execution Subsystems'. Each execution subsystem could be configured to handle programming tasks...
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 Projects
Since the release of labview project explorer, it has become easier now to manage labview projects. Labview project file names ends with .lvproj as apposed to .vi which is the file extension for labview 'subroutines' and .exe for executables on windows OS. Through labview projects, one can easily create new vis, libraries, controls, classes even executables and installers....
