Novel Data Acquisition and controls System (DACS) Demonstration

Completed Technology Project

Project Introduction

The combined data acquisition and controls architecture is eliminating the need of the widely popular programmable logic control (PLCs).   The system uses either Peripheral Component Interconnect (PCI) or PCI eXtension for Instrumentation (PXI) buffered controls cards for analog and digital outputs (ADO) in a chassis with a General Purpose Interface Bus (GPIB) interface.  The GPIB will connect to a commercially available off the shelf ADO. The control cards will output a timing sequence similar to that of a PLC (similar voltage and current levels) however the sequence data will be preloaded on a buffer prior to test.  The buffer will then be stepped through when the sequence begins.  The loop rate of a PLC can be surpassed by performing a buffered output so a finer resolution of controls’ activities can be achieved. Additionally one piece of LabView™ code will be required for this project to replace a mix of Wonder Ware®, LabView™, and Microsoft® Excel.
