Error 10805 occurred at AI SingleScan

I have 6024E. I get the following error message when I try to run Real-Time PID Control.vi and PID Control Loop.vi:

NI-DAQ LV: The clock rate is faster than the hardware can support. An attempt to
input or output a new data point was made before the hardware could finish
processing the previous data point. This condition may also occur when glitches
are present on an external clock signal.

My input channel is a pair of analogue input pins in differential mode, and my output channel is an analogue output pin (All hooked up to BNC connectors). The output is connected to some equipment, while the input is not connected to anything. I am just testing my setup right now, before using some actual devices for input. I have done th
e exact same thing before, and it worked. I have tried lengthening the Loop Delay time to 50ms in PID Control Loop.vi, and lowering the Rate (S/s) in Real-Time PID Control.vi. Yet I still get the same error message. Any suggestions as to why this happens? Thanks

Actually, when I try to run the programs again now, the error is 10845...strange...

Is it possible that you can post your VI here? It's sounding like you're setting up some buffered acquisition, then calling a single point daq VI while your buffered acquisition is going. This will give you an error like that.

Greetings,

These are strange errors to be receiving with these examples. Does your NI 6024E function correctly in Measurement & Automation Explorer? Do other DAQ example programs also generate these errors? It is possible that your NI 6024E is not functioning properly. You indicated that you have successfully executed these examples in the past. Were you using this NI 6024E?
