Cdaq

[Firestorm100_CAT]

Hello Everyone, 

    I use a cdaq 9174 with two models : NI 9215 to mesure torque and NI 9401 to mesure rotation speed. 

    I need to use these 2 models to get data from a torque meter.

    I did my VI ,for the speed is a digit input and the torque is a analog input.

    My question is , I can use one Daqassistant but I will have synchronsation problem between the 2 models? or is better to use 2 Daqassistant ( 1 is for NI9215 and the 2 is for NI9401).

thank's

I am just purely against using the DAQ Assistant.  You really should learn to use the DAQmx API (start here).

But to your core question:  A task can only have 1 type of signal.  Digital Input and Analog Input are different types.  So you will need 2 tasks in order to do this.

HI,

 Thank you for your answer.

  DAQmx API can only have 1 type of signal and one card Ni in the same time as the Daq assistant?

The concept of Task is the same whether you use DAQ Assistant or DAQmx drivers.

FYI - DAQ Assistant also uses DAQmx drivers behind the scenes.
