error -10805 AI Buffer Read

[luisa]

I am working with a Ni 6034E 200kS/s Multifunction I/O 16 Inputs, 16 bits,
driven by a PostNova Daq Control software. It was working fine till this morning when the code: Error -10805 AI Buffer Read starts to appear.

Do you have any suggestions information about this error and his origin ?

Thank you very muvh in advance

Luisa,

if I am not getting this wrong, you are driving the data acquisition with your 6034 using an external clock to sample data, aren't you?
Well, if you are using an external clock, all you need to check is that the external clock has not changed over time. The error basically means that the clock you are providing to the 6034 is too fast for the analog circuitry to work correctly.
Check the clock and if the problem persist just let us know.
