With the recent release of the new families of digital I/O products from National Instruments, its customers now have access to a wide range of high-reliability industrial features that were not previously available. These features include programmable change detection, input filters, programmable power-up states, and digital I/O watchdogs, all of which are programmable through NI-DAQmx. Many of the new products also feature isolated inputs and outputs for connecting to high-voltage, high-current, or high-noise signals. This white paper describes the operation of these features, demonstrates the features in typical scenarios, and illustrates how to program the features in LabVIEW. For more information about any of these features or the products that offer them, see the links at the bottom of this document.
