File Transfer Capability
When running on an FP-20
xx
, the RT Engine has a File Transfer Protocol
(FTP) server. The FTP server gives you the ability to use any standard FTP
utility for transferring files to and from the hard drive of the FP-20
xx
.
You must provide the correct password when opening a connection to the
FP-20
xx
if the configuration is locked in Remote System Explorer.
Note
Transferred files must use the 8.3 file naming convention.
For programmatic file transfer control in LabVIEW or LabVIEW RT,
use the Internet Developers Toolkit, included in the LabVIEW Enterprise
Connectivity Toolset. Refer to the National Instruments Web site at
ni.com
for more information about purchasing and using the LabVIEW Enterprise
Connectivity Toolset.
Note
Contact NI to determine whether the toolkit version you are using can be
downloaded onto the FP-20
xx
.
Hardware Watchdog
In addition to the network watchdog described in Chapter 4,
, the FP-20
xx
network modules support the hardware watchdog
available in LabVIEW RT. You can use the hardware watchdog to verify
programmatically that the FP-20
xx
is responding within a given time
period. If the module stops responding because of a problem in the
program, it can be configured to reset the FP-20
xx
or generate an
occurrence in LabVIEW.
The hardware watchdog VIs are on the FieldPoint palette at
FieldPoint»FieldPoint RT»FieldPoint Watchdog
. For examples that
show how to use the hardware watchdog, refer to the RT Watchdog
(PXI-8156B)
.llb
file installed under
\\examples\rt\
. For additional
information, refer to the help for the watchdog VIs.
