NEWS RELEASE – Nov. 16, 2004 – National Instruments today announced two new PXI real-time controllers for programmable automation controller (PAC) and deterministic data acquisition and control design applications. These new controllers, combined with the NI LabVIEW Real-Time Module, deliver deterministic, real-time processing for the rugged, mo

dular PXI platform.

The NI PXI-8187 RT controller is a high-performance controller with a 2.5 GHz Pentium 4 processor and up to 1 GB of double data rate (DDR) RAM, which delivers faster processing. With the new controller, engineers now can take advantage of the additional processing power for more complex or analysis-intensive applications such as hardware-in-the-loop testing, rapid control prototyping and machine condition monitoring. The new PXI-8187 RT controller increases the performance of real-time PXI applications, which means faster control loops and more analysis in the loop.

The NI PXI-8184 RT controller is a new mid-performance controller with an 850 MHz Celeron processor. The cost-effective PXI-8184 RT controller is better suited for less processor-intensive industrial data acquisition and OEM applications. This controller provides an alternative to high-volume or cost-sensitive applications that require reliable and deterministic real-time processing.

Because both controllers have solid-state drive options, engineers can deploy real-time PXI systems in harsher environments than rotating drives can sustain. LabVIEW Real-Time works with a wide range of PXI and CompactPCI modules through industry-standard virtual instrumentation software architecture (VISA) drivers.
