National Instruments 781787-02 CompactRIO Controller

The 781787-02 is a component of the cRIO‑9082 model series by National Instruments. This embedded controller is designed for advanced control and monitoring applications. With a Xilinx Spartan-6 LX150 FPGA and a 1.33 GHz dual-core Intel Core i7-660UE processor, it has a sturdy architecture. It provides dependable performance for industrial automation workloads with 32 GB of nonvolatile storage and 2 GB of DDR3 system memory.

Numerous connectivity options are available on this CompactRIO Controller to allow for external device interaction. It has two Gigabit Ethernet ports for networking, four USB ports for mass storage device connections, one VGA port for video output, and two serial ports (RS-232 and RS-485/422) for peripheral connectivity. Its capabilities are further expanded by the MXI-Express interface, which allows connection to an MXI Express chassis.

In order to ensure effective processing for real-time applications, the CPU runs at a base frequency of 1.33 GHz and can reach 2.4 GHz in single-core Turbo mode. System speed is increased by optimizing data access through the shared 4 MB L3 cache and the on-die 256 KB L2 cache for each core.

The Ethernet ports provide auto-negotiation for transmission rates ranging from 10 Mbps to 1000 Mbps. They also support 10BaseT, 100BaseTX, and 1000BaseTX standards for network communication. The maximum baud rate supported by the RS-232 serial port is 115,200 bps, while the RS-485/422 port can accommodate up to 320,400 bps, meeting a range of communication needs.

Connectivity options for the controller are increased by the MXI-Express connection, which enables 2.5 Gbps high-speed data transfer. Integration with USB mass-storage devices is smooth because of USB 2.0 ports' maximum data rate support of 480 Mb/s.

The CompactRIO Controller 781787-02 is appropriate for use in tough industrial situations due to its robust and fanless construction. Application development can be made more flexible by the fact that it can run on Windows Embedded Standard 7 (WES7) or actual-time operating systems.
