It can also be used to monitor whether USB devices connected to cFP-2220 are supported.
Normal operation: OFF.
5. USER1 and USER2
User defined switches can be used in LabVIEW to read status using RT Read Switch VI or FieldPoint Read VI.
Typical application: Choose different startup VI or control modes.
LED status indication and fault codes
POWER LED: green=using main power supply (V1), amber=using backup power supply (V2). Not lit=insufficient power supply.
Status LED: It goes off during normal operation. The number of flashes indicates a specific error:
Measures for handling the meaning of flicker frequency
Controller 1 is not configured with network parameters in MAX
2 software errors (such as upgrade interruption) reinstalling software in MAX
3. Check the position of the SAFE MODE switch while in safe mode
4 software crashes twice in a row (without restarting) usually due to memory exhaustion, optimize RT VI memory usage
Always on, unrecoverable hardware error. Contact NI for repair
User LED A/B/C/D: can be controlled through FieldPoint Write VI: 0=off, 1=green, 2=amber.
Data storage and file transfer
CompactFlash (cFP-2220 only)
Supports Type I/II, with a maximum of 512 MB. It must be plugged in or unplugged while powered off.
Drive letter: D:. It can be read and written directly through LabVIEW file I/O.
To obtain data at runtime, use an FTP client to download from the D: drive.
USB flash memory (cFP-2220 only)
Only supports the following models: SanDisk Cruzer Micro、PNY Optima Pro Attache、Swissbit Swissmemory USB Minitwist。
Hot plugging can be performed in normal environments, but it is prohibited in hazardous areas or when connected to high voltage.
Mapping drive letter: U:.
FTP server
The LabVIEW Real Time engine has a built-in FTP server. Any standard FTP client can access the internal storage of the controller (C: disk).
If lock is configured in MAX, the correct password must be provided.
Remote front panel and embedded application management
CFP-22xx supports multiple remote front panels connected simultaneously. The client can view and control VI through LabVIEW or a web browser (IE 5.5 SP2 or above or Netscape 4.7 or above).
Best practices:
Keep the front panel simple and avoid using attribute nodes, otherwise remote operations may experience delays.
Users cannot change control values through remote panel programming (they can only be modified by the embedded VI itself).
If you need more advanced remote file transfer or control, you can use the Internet Developers Toolkit in LabVIEW Enterprise Connectivity Toolset.
Advanced troubleshooting and system recovery
11.1 Uncontrolled startup of applications resulting in controller unresponsive
Disconnect the power and turn on the NO APP or SAFE MODE switch.
Re power on, the controller will not run user applications at this time.
Connect the controller in MAX, delete or correct the problematic VI, then restore the switch to OFF and restart.
11.2 Unable to detect controller in MAX (except in safe mode)
First, try reinstalling the software using MAX (right-click on Remote System → Install Software).
If it is invalid, it may be necessary to format the internal storage.
Format steps:
Turn SAFE MODE to ON and restart the controller.
Expand Remote Systems in MAX and locate the FieldPoint station.
Right click and select Format Disk.
After formatting, the network must be reconfigured and the software must be reinstalled. Be sure to install LabVIEW Real Time 8.5.1 or higher (older versions are not compatible with cFP-22xx).
11.3 Other abnormal phenomena and countermeasures
Possible causes and solutions for the phenomenon
Under normal mode, the STATUS LED is constantly on and amber is a serious error. Please contact NI support
After setting the IP, if the restart still returns to the old IP or if the IP RESET switch is not turned back to OFF, reconfigure after setting OFF
The Status LED flashes twice (during normal operation). The software is damaged and needs to be reinstalled
Controller false alarm disk full file system abnormal formatting internal storage
The Ready LED of the I/O module is off in normal mode and on in safe mode. Check the LabVIEW version and module driver for software configuration errors or module incompatibility
FTP sees strange file/folder names, file system corruption, formatting
