I have a PXI-1010 chassis with a 8175 controller and three PXI-6070E DAQ cards. I am measuring 16 channels per card. I receive an error 10845 from NI-DAQ LV stating "Because of system and/or bus-bandwidth limitations, the driver could not read data from the device fast enough to keep up with the device throughput; the onboard device memory reported an overflow error". The error occurs when reading the first channel of the next device when the devices are in adjacent slots. The devices are in slots 8,7,6. If I move the devices to slots 8,6,4 then no error occurs. I have to support 6 PCI-6070 devices in the future, so leaving empty slots will not be an option. We are running Win 2000 and LabVIEW 7. This error occurs for sampling rates >20K per channel.
Has anyone seen something like this before? Wayne Lewis ________________________________________________________________ The best thing to hit the internet in years - NetZero HiSpeed! Surf the web up to FIVE TIMES FASTER! Only $14.95/ month -visit www.netzero.com to sign up today!
