Error BFFFA 2003 in niDMM Read .vi

[Andrewbft]

I have a sequence in Teststand that calls a read from an NI PCI DMM 4060. an error appears every so often saying ERROR BFFFA 2003 in niDMM Read.vi. Does anybody know what the error is about and how to solve it?

Hello,

The error BFFA2003 means NIDMM_ERROR_MAX_TIME_EXCEEDED (see image attached below).

All you need to do is give the NI DMM Read function more time to fetch the readings, this is, enter a higher time in the "Maximum Time (msec)" paramater of the niDMM Read.vi function.

Hope this helps,

I have tried to extend the time allowed but the problem still appears. I have now replaced the card and the error has stoped appearing. Must have been a hardware fault

I have a similar problem with Error BFFA2003 occuring in DMM Read Multi Point.vi.  I see that the Maximum Time parameter is set to Auto TL by passing a value of -1.

Can anyone tell me how this 'Auto TL' works as distinct from setting an actual value in ms?

This problem has only just appeared in software that has been working under various issues of LabVIEW (currently 8.5) for mamy years.  Could the problem be a hardware issue?

If your program hasn't changed, then it could be a hardware issue (but it's not a sure thing). Are you using triggers? Can you use the device from the SFP normally? Can you swap the card with another one (if you have it) and see if that works?

Let us know, good luck!
