error 200279 once every 24 hours (SignalExpress)

[darylt]

I am using the cDAQ 9174, with SignalExpress 2014, version 14.0.0, and the following modules: 9229, 9211, 9482.

The program runs fine, except every 24 hours I receive error 200279. Please see event log in the attachment. I opened task manager and waited for the error event to occur, but did not see any application popup that may explain the error.

The computer is not connected to the internet.

The computer has 24 GB of RAM.

Any thoughts as to why I receive this quite predictable error?

Hi darylt,

You might be able to find information regarding this error code on this link.

Basically it seems to be that the data acquisition or the logging is very slow, so you will need to speed the process a little bit more or to expand the buffer size more.

Hi Luis,

Thank you for the reply.

In SignalExpress, is it possible to increase the buffer size or monitor the buffer?

I am reading continuous samples, Sample To Read = 25,000, Rate = 25,000, and logging every 1s.

Hi darylt,

Try setting less amount of samples to read, a less rate an maybe logging a little faster. Have you tried something like this? In this link, you should be able to understand a little better the meaning of each of the options.
