Design the A/C control model and In vehicle ECU
prototyping test system
•In addition to the ECU prototype model which controls the
air conditioner as like a real ECU does, a cRIO itself can
measure and save all temperature data and control
parameters in a moving car.
•Benefit from size, low power consumption, speedy boot up
from Ignition ON

FedEx Fire Suppression System with NI Single-Board RIO
• Embedded temperature monitoring
and control of suppression system
• Protects packages, pilots, and planes
from fires
• Rapid embedded prototyping with
CompactRIO and LabVIEW – fast
deployment with NI Single-Board RIO
“We were able to start with LabVIEW and
CompactRIO for prototyping and quickly migrate
our code to the new NI Single-Board RIO for
deployment – all in less than a year.”

FAQs
•
Problem:
I have used the specialty digital
functionality of CompactRIO Scan Mode
to configure a digital module as a
counter or quadrature encoder and need
to reset it programmatically. How can I
do this?
Solution:
The Reset Counter (Scan Interface) VI
can be used to reset specialty digital
counters, as well as the position
measurement of a quadrature encoder.
It can be located here:
