What are the ERR_RFR counting in NI-FBUS Monitor, and why is there nothing about in the manual about these messages?

[markr1957]

I am recording a long monitor file using NI-FBUS Monitor 3.0.1 to try and capture reported device problems, and in the Statistics window I see what appear to be counts of some sort of errors:

ERR_FFER

ERR_FCSE

ERR_NEPT

ERR_RFOR

ERR_RFUR

ERR_RFR

If these counts have any meaning can you explain what they are telling me, and perhaps include the information in the User Manual for all users. This might be exactly what I need to know, but I have no means of knowing due to the lack of useful information in the User Manual.

Yokogawa tell me they are seeing IOP errors and CNF errors from our device, but NI-FBUS Monitor gives no indication of these errors that I have been able to see, or if it does I cannot find anything.

Hi,

To display the detailed statistics and spell out parameter names, please select the Verbose option in the left panel of NI-FBUS Monitor main window. These error abbreviations will be displayed in full names.

The errors you listed are invalid FDL PDUs which come from data link layer. All data link layer errors are displayed in Monitor. As for IOP and CNF errors, I am not sure in which layer they occur. I think I need more information about these two errors.
