analog input rates, 1 MHz simultaneous analog output rates, and a denser 3 million-gate FPGA chip.
National Instruments recently released 12 new reconfigurable I/O (RIO) devices – seven new PCI/PXI R Series devices and five new NI CompactRIO I/O modules – for embedded digital signal processing, custom protocol development, and high-speed control. You can use these intelligent devices to create your own data acquisition and control circuitry by programming FPGA-based hardware with the National Instruments LabVIEW graphical development platform and the LabVIEW FPGA Module. With the NI LabVIEW Digital Filter Design Toolkit, you can take advantage of automatically generated LabVIEW FPGA code and easily implement digital filters on the FPGA chips of your RIO devices. The LabVIEW code in the FPGAs of these devices can run at rates up to 40 MHz, making these devices ideal for ultrahigh-speed analog and discrete control.
New R Series Devices
The new NI R Series devices feature 40 MHz digital I/O rates, 200 kHz simultaneous analog input rates, 1 MHz simultaneous analog output rates, and a denser, 3 million-gate FPGA chip.
“LabVIEW FPGA and RIO technology is the heart of our data acquisition and control system, and the new, denser, 3M gate version of R Series devices provide for additional onboard processing and future expandability,” said Michael Wiltberger, principal engineer at OptiMedica Corporation. “By leveraging an off-the-shelf product, we are reducing our engineering and maintenance costs. At the same time, the FPGA offers greater safety and system reliability than a custom solution.”
New CompactRIO Modules
The five new NI CompactRIO modules expand the RIO embedded platform to support up to 32 industrial digital output channels per module, 100 ns I/O rates, and 100 kS/s current output. With the new 32-channel NI 9476 module, you can control 24 V actuators with up to 250 mA of current drive per channel. With RIO technology, you can use LabVIEW FPGA to program the NI 9401 to implement custom, high-speed counter/timers; digital communication protocols; pulse generation; and much more. Save on field wiring costs by using the new D-Sub connector versions of the NI 9221 and NI 9201 industrial analog input modules. Avoid spending time and money wiring a complete system by hand by buying low-cost, industry-standard D-Sub cables and directly connecting to CompactRIO for large OEM applications.
