The new MXI-Express RIO 14-slot expansion chassis with onboard Virtex-5 FPGAs offer a high-end solution for large applications that require high channel counts, mixed I/O for a variety of measurements and custom signal processing and control algorithms. The MXI-Express link delivers high bandwidth for streaming data to and from multiple chassis from a single controller, offering hundreds of C Series module slots and thousands of channels of analogue, digital and communication I/O including strain, acceleration, channel-to-channel isolated voltage input and simultaneous voltage. The new chassis are ideal for hardware-in-the-loop (HIL) testing, industrial machine monitoring and complex research applications.
“Using the MXI-Express RIO chassis, we can build highly customisable, high-channel-count conditioned measurement systems,” said Albion Knight, Vice President of Green Mountain Research Inc. “We now use LabVIEW FPGA to program the FPGA within the chassis and add custom signal processing, control and timing to solve a variety of high-channel-count control and acquisition applications.”
The NI 9148 8-slot Ethernet expansion chassis adds flexible distributed I/O to RIO systems. With standard CAT 5 Ethernet cabling, it communicates with NI CompactRIO, real-time PXI controllers, the NI industrial controller or any networked Windows PC. The flexibility of the NI 9148 chassis makes it an ideal choice for seamlessly adding expansion I/O to an existing network. With an onboard FPGA and LabVIEW FPGA software, engineers can implement custom signal analysis, control and safety interlocks local to each chassis to create a truly modular system. Engineers can also use more than 50 third-party C Series I/O modules with these new chassis, including wireless modules based on 802.11, GPS, Edge, and other technologies. When combining the new NI 9148 Ethernet chassis with wireless modules from S.E.A. Datentechnik GmbH., engineers can turn the NI 9148 chassis into wireless expansion systems for application with difficult or impossible cabling.
These expansion chassis are an extension of the NI RIO platform, which delivers a wide variety of solutions at different prices and performance levels for control, design and test applications. The common NI RIO architecture consists of a processor, customisable FPGA and modular I/O, which combine to create a flexible system that solves complex application problems. Engineers can use the LabVIEW graphical development environment to program the processor, FPGA and I/O of their RIO system to create an embedded system that rivals the performance and optimisation of custom hardware.
