What function is used to read Angular Position form a Task?

[johnoc]

I have created a DAQmx task in MAX. This task configures a counter on a PCI-6259 to take the A and B counts from an encoder and give the Angular Position. What function do I use to read the value since I am no longer reading counts I am reading the position?

Thank you in advance for any advice!

Hello John OC, 

Are you looking for a function in LabWindows/CVI which takes the place of the task in Measurement and Automation Explorer? If you are the function is the DAQmxCreateCIAngEncoderChan with more information on this page, http://zone.ni.com/reference/en-XX/help/370471W-01/daqmxcfunc/daqmxcreateciangencoderchan/.

Hi Izzy,

I have Created the task in MAX. The task takes input into the counter from an encoder and converts it to angular position. Do I still use the DAQmxReadCounterF64 function to read the counter? I am guessing that I do and that the function returns the angular position rather than the raw counts. Not sure though.

Thanks for taking the time to respond.
