control pump with daq

[sunny dee]

Hi, I've recently purchased the PCI-6221 M series DAQ card.

I have a BALDOR pump controller that I want to control. The controller takes 7 digital inputs as control.

What is the best way to implement this using Labview? I want to have buttons on the VI that will allow the user to start,stop,choose direction of the motor (all these are simply controlled by a single digital signal each).

Will I just have to use boolean buttons, and one of the states will be to output a signal?

Thanks!

Sunny

Hello Sunny. Thank you for contacting National Instruments. I am not too familiar with the BALDOR pump controller. Does it start/ stop/ choose direction by setting a specific digital line high or low? If this is the case then you can use an example in LabVIEW that specifies if the line is high or low based on a boolean control. Go to the Help Menu and select Find Examples. Browse Hardware Input and Output>>DAQmx>>Digital Generation>>Write Dig Chan.vi. Please let me know if you have any questions. Have a great day!
