National Instruments 781716-01 CompactRIO Controller

Part number 781716-01 from National Instruments is the version of the cRIO-9081 CompactRIO Controller with a Intel Celeron U3405 processor that runs a real-time operating system (OS). This processor boasts dual core capabilities and has a CPU frequency of 1.06 GHz. In addition, the 781716-01 features a Xilinx Spartan-6 LX75 reconfigurable FPGA.

The 781716-01 has two Network/Ethernet ports that support various interfaces, all of which are compliant with IEEE 802.3 standards. Additionally, this cRIO controller has two serial ports which offer multiple configurations for the data bits, parity, flow control, and stop bits of the device. The maximum baud rate of the RS-232 Serial Port is 115,200 bps, while the max rate for the RS-485/422 (DTE) Serial Port is 230,400 bps.

The MXI-Express Port of the 781716-01 has a cabling distance up to 7 meters long, and it offers a communication rate of 2.5 Gbps. The controller boasts four USB 2. 0 Hi-Speed ports that offer an impressive maximum data rate of 480 Mb/s. Each port can handle a maximum current of 500 mA, which helps ensure seamless connectivity with additional devices. Moreover, the video port (VGA) of the 781716-01 is capable of incredibly clear visuals by supporting displays with a maximum resolution of 1600 × 1200.

In terms of software requirements, the 781716-01 requires versions of LabVIEW, LabVIEW Real-Time Module, or LabVIEW FPGA Module that are 2011 or later. Any NI CompactRIO Device Drivers should be version 4.0 or later.

The 781716-01 CompactRIO controller includes an internal Real-Time Clock that has an accuracy of 200 ppm, and features screw terminal wiring with a copper conductor wiring gauge range of 14 AWG to 12 AWG (2.0 mm² to 3.0 mm²).
