VI to Track position with a Rotary Encoder using NI9401??

[StevenCrocker]

I am very new to LabView, and I need a VI to track radial position (0-360°), using a rotary encoder.  It is 2000 pulses per revolution. and there is a phase shift when direction changes.  Any ideas? I am using labview 2009.

Steven:

What hardware plugging the 9401 into?

The examples for doing encoder measurements are located within the LabVIEW example finder.

In LabVIEW, go to: "Help --> Find Examples" to open the example finder.

From there, browse to: "Hardware Input and Output --> DAQmx --> Counter Measurements --> Positioin."

Hope that helps!

She is plugged into a NI cDAQ-9172.

Thanks for your help.  I will see what I can accomplish from here.
