Error and Status Messages

Unable to load Trend Link DLL!

NetDAQ Logger is unable to load the Trend Link c:\Program

Files\Fluke\tl\tbase.dll into memory.

Check that you have sufficient memory space to load tbase.dll, that the tbase.dll has not been corrupted, or you are not trying to operate with portions of an older version of Trend Link. Reinstall Trend Link following the procedures in Chapter 2.

Unable to open Communications Configuration File!

You tried to open the Communications Configuration File but failed.

Check the read/write permissions for the c:\Program Files\fluke\netdaq\ccf.cfg file. This error can be caused by having this file Read-Only. Remove the Read-Only property from the file. Other causes include the ccf.cfg file does not exist or is corrupted. In either of these cases, close the application and delete the current ccf.cfg file. Then restart the application and select the Communications Config command from the Setup menu to create a new ccf.cfg file.

Unable to open communications socket with instrument!

You tried to communicate with the instrument and the Socket Port could not be opened.

The Windows resources are out of memory or there is a configuration problem with the networking software. For example, if you accidentally close the Winsock icon you will receive this message. Close all applications and restart Windows or close NetDAQ Logger and try again. Also check your networking software.

Unable to Open Mx+B File!

You have specified an Mx+B file that is not readable.

Make sure the file is a text file, and that it resides in a directory with the proper read permissions.

Unable to open RS232 port!

Your host computer RS-232 port cannot be opened.

Check your host computer RS-232 port operation. Your COM port may be disabled for an internal modem or other device or may be in use by another application. The RS-232 port is used only for calibration procedures.
