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.
Communication
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
