Hey All,
I am currently running DASYLab 13.0 with the latest version of NI MAX (14.0.1f1). The hardware that I have is the cDAQ-9188.
I am attempting to read psi, temperature, and flow; each has a seperate task set up in MAX. The reason I did this was to make yearly calibration updates easier on our Quality Dept, and because the flow task has a higher rate of aquisition.
I've set up my DASYLab worksheet as seen below in the attachment. When I run the work sheet I get an imediate error (attached also). My assumption is that DASYLab does not like to have three different tasks running at the same time because when I delet the flow and temp tasks I do not get the error. Does anyone have a suggestion as to how I can get around this issue?
Thanks

How is the write data module configured?

The Write data module is likely the problem if the tasks are set up for different sample rates.
The ASCII data format requires that all of the inputs have the same sample rate, block size and start time.
Likley the AI is overrunning because DASYLab is waiting for the Write module, which is waiting for the temp and flow.
Either sample all at the same rate, or store the data into different files, or use the DASYLab DDF format.

I tried removing the write module all together, and I am still getting the same issue.

Can you contact Measurement Computing in the US? I'm not sure where you're located. This sounds more complex than I thought.
We'll need to gov over all of your task settings, as well as the configuration of each module.
