DAQ assistant!?

[Viller]

hi

I can't seem to get my DAQ to work!? I have connected a DAQ-9172 (USB) with a NI 9265 module (4-20 mA output). I have installed it at it seems to be OK (it checks out ok in MAX)..... but when I try to use the DAQ assistant in Labview I get the following error? (see attachment) what do I do wrong?? I dont think there are a lot of things to chaneg in the DAQ assitant!?

Hi Viller,

You need to increase the buffer size for your AO operation. What you need to do is convert DAQ assistant to DAQmx code(Right click DAQ assistant->Generate DAQmx code). Then use "DAQmx Configure Output Buffer.vi" to override the automatic output buffer allocation.

Here is a KB-link that adresses this issue: https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000P7jnSAC&l=en-US

hi

thanks for your answer! I'm a newbe in labview and I have a NI cDAQ-9172 (USB) and a current out module (NI9265)... Can someone direct me to a descriping "how to - step by step" manual on how to write data out! It not as simple as a thought 🙂
