National Instruments 779563-01 CompactRIO Controller

The 779563-01 is an embedded real-time controller from National Instruments, designed for advanced control and monitoring applications. This part number describes the cRIO‑9012 NI module. This sturdy, fanless controller, with its 400 MHz CPU, 64 MB DRAM, and 128 MB nonvolatile storage, is perfect for settings that demand high dependability and extended temperature operation. It may be connected to a variety of devices, including displays and input peripherals, thanks to its one Ethernet connector, one USB port, and one RS-232 serial port connections.

With auto-negotiated connection rates of 10 Mbps or 100 Mbps, its Ethernet port supports the 10BaseT and 100BaseTX standards, guaranteeing strong network connectivity at lengths of up to 100 meters per segment. The USB port can handle popular USB mass-storage devices such flash drives and USB-to-IDE converters configured with FAT16 and FAT32 file systems. It has a maximum data rate of 12 Mb/s and can supply up to 500 mA of electricity. Because of its adaptability, data can be transferred and stored even when the controller is in use.

For industrial applications where serial device interface is common, the RS-232 serial port significantly increases the controller's versatility by facilitating connections to a wide range of serial devices. In order to guarantee accurate timestamp data, the 779563-01's system clock also synchronizes with its internal high-precision real-time clock at launch. Time-sensitive applications require precise timekeeping, which the internal real-time clock can fix. It can also counteract system clock drift.

The 779563-01 lacks integrated C Series I/O module slots in spite of its small form factor. Compatibility with a CompactRIO Chassis is a requirement for the use of C Series I/O modules. Scalability and flexibility are made possible by this modular design, which lets the system be customized to meet the demands of different applications.

The SMB connector on the controller has logic low of 0 V and logic high of 3.3 V, which are both input and output characteristics appropriate for CMOS logic levels. With an input voltage range of -500 mV to 5.5 V, it can source or sink currents up to ±50 mA. Ensuring dependable digital interface, the SMB connector has an input capacitance of 2.5 pF and resistive strapping of 1 kΩ to 3.3 V.
