National Instruments 783451-01 4-slot CompactRIO Controller

The part number 783451-01 from National Instruments is the identifying part number for the cRIO-9031 4-slot CompactRIO Controller. This controller features an Intel Atom processor, a reconfigurable FPGA, and various connectivity options allowing it to automate, monitor, and control industrial processes. The 783451-01 is equipped with an Intel Atom E3825 dual-core processor running at 1.33 GHz. It features 1 MB of shared L2 cache memory and runs the 64 bit version of the NI Linux Real-Time operating system. It supports LabVIEW Real-Time and LabVIEW FPGA modules, as well as the C/C++ Development Tools for NI Linux Real-Time for programming the controller and developing processes.

The 783451-01 4-slot CompactRIO Controller features 2 Ethernet ports, supporting 10Base-T, 100Base-TX, and 1000Base-T Ethernet interfaces, with auto-negotiation for communication rates of 10 Mb/s, 100 Mb/s, and 1,000 Mb/s. Each port can handle a maximum cabling distance of 100 meters per segment, and the device follows the IEEE 802.3 standards. For serial communication, the 783451-01 provides both RS-232 and RS-485/422 ports. The RS-232 port supports a maximum baud rate of 115,200 b/s and various configurations for data bits, stop bits, parity, and flow control. The RS-485/422 port, isolated to 60 V DC, supports similar baud rates and configurations, with the added benefit of multiple wire modes and enhanced communication distance capabilities.

The Controller features one USB device port and two USB host ports, all conforming to USB 2.0 Hi-Speed standards, with a maximum data rate of 480 Mb/s per port. The host ports can supply up to 1 A of current in total. Additionally, the controller includes a Mini DisplayPort, capable of supporting a maximum resolution of 2560 × 1600 at 60 Hz, facilitating easy connection to external monitors for configuration and monitoring purposes.

The 783451-01 comes with 1 GB of DDR3L processor memory, providing sufficient volatile storage for running complex applications. Nonvolatile storage options include a 4 GB solid-state drive and support for user-supplied SD and SDHC cards up to 32 GB. The memory architecture ensures high data throughput, essential for demanding industrial applications.
