Description
The CompactRIO Chassis, part number 781316-01, is a high-performance modular system designed for industrial control and monitoring applications. The model NI-9157 features a 14-Slot configuration, providing ample space for various I/O modules to fit the needs of complex setups.
At the heart of the NI-9157 is the powerful FPGA Virtex-5 LX85, which offers robust processing capabilities for real-time data handling and analysis. The system utilizes an MXI-Express interface, ensuring high-speed communication between the chassis and connected devices.
Users can daisy-chain up to 6 NI MXI-Express RIO models together, with the capability to manage up to 8 chains per controller. This flexibility allows for significant system expansion and customization according to specific project requirements.
The chassis offers two power-up options: “Do Not Autoload VI” and “Autoload VI on device power-up”, giving users control over the initialization of their LabVIEW FPGA applications. An external power supply is required for power filtering and regulation, ensuring stable operation. The system smartly draws power from the higher voltage supply when multiple sources are available, and it includes integrated reverse-voltage protection for added safety.
An additional feature is the NO FPGA APP Switch, which prevents LabVIEW FPGA applications from loading at startup, offering a safeguard for troubleshooting and system maintenance. The chassis is also equipped with LEDs: one bi-color power LED and three user-configurable FPGA LEDs, providing visual feedback on the system’s status and activity.
