acquire with a single task different signal types

[matomato]

Hello,

I am still here and continue to have problems.

How is it possible to acquire currents and voltages simultaneouusly using a single task?

I am usingNIcDAQ 9174 and NI9207 and a  producer consumer scheme.

During the configuration of the DAQ assistent , I create a task where the ch 0, 1 and 2 are Voltages and the channels 8 and 9 are currents. When I run the daq ( after its creation) it works but when I run the VI and I receive the error message " Error -200072 occurred at DAQmx Create Channel (AI-Current-Basic).vi:3.  What I am wrong? Can I use a single task for different signals or do I need to create two tasks, one for the currents and the other for the voltages? I attach my VI.

Thanks for the help.

It sounds like you are getting the error because the task already defines the channels "During the configuration of the DAQ assistent , I create a task where the ch 0, 1 and 2 are Voltages and the channels 8 and 9 are currents." You do not need to create the channels or add them to the task if you've defined them in the task.
