Embedded Control Made Easy
LabVIEW Real-Time enables you to perform digital and analog
control on the FieldPoint platform. With LabVIEW Real-Time
embedded and running on a cFP-20xx controller, you can perform
simple digital control with Boolean logic, as well as more advanced
analog control, such as PID and fuzzy logic. The PID Control Toolset
for LabVIEW has drop-down blocks for basic and advanced PID,
feed forward, and fuzzy control. You can also use it for linear and
nonlinear testing, modeling, and simulation. When developing a
control system, you can take advantage of LabVIEW to implement
basic control or easily incorporate advanced control techniques, such
as disturbance decoupling, gain scheduling, and fuzzy logic control.
For beginner users, powerful tools such as Autotuning PID make life
easier and more productive. For embedded systems, you can
effortlessly deploy your LabVIEW application on the real-time
Compact FieldPoint hardware target.
Web-Enabled Hardware
With remote panels, you can use a Web browser to connect to the
front panel user interface for your LabVIEW application. Several
Web browser clients can simultaneously view the front panel, while a
single browser can both view and control the application. cFP-20xx
real-time controllers feature an embedded Web server that handles
up to 20 simultaneous remote panel connections. The cFP-20xx
controllers also offer static Web pages to display system information
and automatically run an FTP server to make it easy to update the
embedded control program or to share logged data.
Embedded Intelligent Data Logging
Compact FieldPoint 20xx controllers all feature built-in nonvolatile
memory for data logging, and with the cFP-2020 you can expand
your storage capacity by using the removable CompactFlash drive.
You can store the data in any DOS-compatible format, including
CSV and XML. Once the data is stored, you can easily transfer it to a
PC using the embedded FTP server on the cFP-20xx. LabVIEW
Real-Time expands the functionality beyond the typical data logger
because you can make additional calculations and decisions to
eliminate logging unneeded data and to perform onboard real-time
processing and control. Compact FieldPoint combines data logging,
data reduction, control algorithms, HMI, and the ability to
communicate with other nodes on the network.

Reliable Embedded Operation
Using cFP-20xx industrial controllers, powered by real-time
LabVIEW, you can create flexible control and measurement systems
to meet your unique application requirements. Because these
controllers contain an onboard processor and nonvolatile storage,
you can perform embedded monitoring, logging, and machine
control. Using the LabVIEW Real-Time module, you can download
your application onto the controller and run the application
disconnected from the host PC. Compact FieldPoint I/O banks
include a number of features for industrial operation, including
2,300 V transient overvoltage protection where dangerous voltage
levels are present, a wide temperature range for operation in hostile
environments, backup power supply connections to protect against
primary power failure, and hot-swappable modules to simplify
maintenance and minimize downtime.
cFP-20xx controllers connect directly to Ethernet and autonegotiate
on the network for 10 Mb/s or 100 Mb/s communication rates.
The Ethernet port serves as a high-speed link for downloading
application code, performing run-time debugging and probing, and
transmitting control and indicator values with a graphical user
interface (GUI) running on a networked PC. You can also use the
Ethernet port for programmatic network communication using
protocols such as TCP, UDP, FTP, HTTP, and DataSocket.
Once deployed, the controllers can communicate peer to peer with
other [c]FP-20xx intelligent FieldPoint controllers, or with passive
network interfaces such as the FP-1601 and FP-1000. In addition,
cFP-20xx controllers can communicate to a Windows computer
running LabVIEW, Measurement Studio, Lookout, or your choice
of National Instruments or third-party OLE for process control
(OPC) client application software. Using industry-standard OPC
technology, the Compact FieldPoint controller automatically
communicates with the FieldPoint OPC server over the network to
read and write I/O remotely without programming. This feature
makes it easy to communicate with Compact FieldPoint using any
OPC-enabled HMI/SCADA supervisory control software and to add
Compact FieldPoint to installations with existing hardware.
