Read in | Print

Overview

The Deterministic Ethernet Product Selection Guide is your free online resource for choosing the hardware and software components you need to build your complete deterministic distributed I/O system. This type of system is based on a master/slave architecture that requires a master controller, a slave chassis, NI C Series I/O modules, development software, and accessories.

Visit the CompactRIO Advisor to easily configure and build your NI CompactRIO expansion system.

Step 1. Select Your Real-Time Master Controller

Use one of the following NI real-time controllers with two Ethernet ports as the master controller for your distributed system:

NI Platform Real-Time Controller Description Additional Hardware
CompactRIO cRIO-9074 400 MHz real-time integrated controller with 2M gate FPGA -
PXI PXI-8108 RT 2.53 GHz Intel Core 2 Duo T9400 real-time controller PXI-8231 or PXI-8232 Ethernet Interface
PXI-8106 RT 2.16 GHz Intel Core 2 Duo T7400 real-time controller
NI PXIe-8130 RT 2.3 GHz AMD Turion 64 X2 real-time controller
PXI-8104 RT 1.86 GHz Intel Celeron M real-time controller
PXI-8183 RT 850 MHz Intel Celeron real-time controller
PXI-8145 RT 266 MHz Pentium real-time embedded controller

Step 2. Select Your Expansion Chassis

The NI 9144 expansion chassis adds deterministic Ethernet I/O to your CompactRIO or PXI system. With its two Ethernet ports, you can daisy chain multiple NI 9144 chassis from a single controller to expand their time-critical applications while maintaining hard determinism with minimal processor resources. With a temperature range of -40 to 70°C and 50 g shock ratings, the rugged chassis is designed for industrial applications.7

Step 4. Select Your Development Software

The NI LabVIEW graphical development environment and the LabVIEW Real-Time Module are designed for engineers and scientists who need to create flexible and scalable test, measurement, and control applications rapidly and at minimal cost. The intuitive graphical development environment provides all the software tools you need for easily adding deterministic distributed I/O to your system. LabVIEW offers easy access to the physical channels using the click-and-drag I/O variable, live test panels, and I/O forcing for troubleshooting. For more information, refer to the related resources below.
