As a modular expansion system, the NI 9144 chassis features the flexibility
to incorporate more measurement types and channels by simply plugging in
additional I/O modules. Plus, attaching another expansion chassis adds even
more module slots for your system. Not only are all I/O modules automatically
synchronized in each chassis, but all the expansion chassis in the network are
synchronized with each other as well.
Overview and Distributed Applications
The NI 9144 expansion chassis adds deterministic Ethernet I/O to your
NI CompactRIO or NI programmable automation controller (PAC) system.
This eight-slot rugged chassis for NI C Series modules communicates
deterministically over an open, real-time Ethernet protocol called EtherCAT.
Multiple NI 9144 slave chassis may be daisy-chained from the master controller
to expand time-critical applications. Supported master controllers all have
two Ethernet ports and include platforms such as CompactRIO, real-time PXI,
and Industrial Controller. The NI 9144 is an industrial-grade chassis designed
for extreme ruggedness, reliability, and a wide -40 to 70 °C operating range.
To customize your measurement and control system, select from more than
50 analog and digital C Series modules. Plus, you can take advantage of the
software configuration and NI LabVIEW programming to make adding real-time
expansion I/O easy.
All C Series modules for single-point analog and digital I/O are supported,
giving you direct connectivity with a wide variety of sensors and actuators.
Each module contains built-in signal conditioning and isolation for extended
voltage ranges and industrial signal types, such as thermocouples, resistance,
voltage, current, and strain. Like the NI 9144 chassis, all modules are UL tested
and operate in industrial temperature and shock environments. Plus, C Series
I/O modules are reusable in other NI hardware platforms, such as embedded
CompactRIO, NI CompactDAQ for USB, and Wi-Fi data acquisition.
For the complete catalog of supported C Series modules, visit ni.com/info
and enter cseries. The modules are listed under the categories for Deterministic
Distributed I/O.
Software
With LabVIEW, you can easily add deterministic expansion I/O to a graphical
programming environment. The out-of-box experience for the NI 9144 simply
involves installing the NI-Industrial Communications for EtherCAT driver on the
NI master controller. Then LabVIEW automatically recognizes all connected
slaves and their modules. The LabVIEW Real-Time Module provides I/O
variables, which offer instant access to the physical I/O values using a simple
drag-and-drop motion. With I/O forcing and live test panels, I/O variables can be
used to monitor system performance and implement advanced troubleshooting.
The NI 9144 also has a 2M gate Xilinx field-programmable gate array (FPGA) that
is programmable with the LabVIEW FPGA Module, giving you high-speed and
customizable I/O timing, inline processing, and control.
