PFI0 start trig e-series

[Django]

Hello everybody,

In my project I have to do some meassuremtens with different senors. I use the NI PCI-6133 and the SCB-68 to read data.

Now my problem. I only try to start the "Acq&Graph Voltage-Int Clk-HW Trig Restarts.vi" from the NI Example Finder and wanted to check out how everything works. So I wired Sensor 1 at AI 0 and AI8 Pin and the start meassurement signal at the "PFI /AI Start Trig" (finally that is the only pin at E series devices to start analog triggering). And then I get this Error:

Error -200265 occurred at DAQmx Control Task.vi:1 Possible reason(s):

An attempt has been made to use an invalid analog trigger source.

Ensure that the trigger source you specify matches the name of the virtual channel in the task or matches the name of a non-scannable terminal that the device can use as an analog trigger source.

Property: Start.AnlgEdge.Src
Corresponding Value: PFI0

Valid Choices: Dev1/ai0

Task Name: _unnamedTask<18>

What is the problem? Did I configure something wrong?

Input source of the DAQmx StartTrigger(Analog Edge).vi is just "PFI0"

My trigger source is a simple power supply with an output of 5V, which I am switching ON and OFF.

(Very simple, but I only wanted to know how everything works). Obviously it isnt so easy 🙂

The problem is that the 6133 is not an E Series device.  It is actually an S Series device.  Because of the nature of the analog front end (since it is simultaneously sampled), you actually use analog triggers off of the channels in your task instead of PFI0.  Like the error says, you need to trigger off of ai0.  If you don't want to trigger off of the source that you are reading, you can add another channel to your task, trigger off of that, and discard that data.

Thanks for your information! Now I knew this, I am going to use the AI0 as my trigger input. Thats no problem.
