Issue Details

    I want to measure angular position and angular velocity from my encoder using a NI module for my cDAQ. How can I know if a module will be able to do this?


One way to determine if a module will be able to measure angular positions and velocity is to simulate the hardware and create the corresponding task in NI MAX, according to the following steps:

  1. Open NI MAX.
  2. Right click Devices and Interfaces.
  3. Click on Create New.  
  4. Select Simulated NI-DAQmx Device or Modular Instrument
  5. Expand the CompactDAQ Chassis list. Select the cDAQ chassis that you have or that you would like to simulate. 
  6. After this, the simulated cDAQ should appear under Devices and Interfaces
  7. Right click the simulated cDAQ and select Configure Simulated cDAQ Chassis.
  8. In the slot of the cDAQ chassis select the module from the dropdown list that you want to test. Click OK. After this the simulated module should appear under the simulated cDAQ. 
  1. Right click the simulated module. Click on Create Task. 
  2. Expand the Acquire Signal list, then expand the Counter Input list.  Expand the Position List and select Angular Position (to test if angular position measurements are possible) or the Velocity List and select Angular Velocity (to test if angular velocity measurements are possible). 
  3. If the simulated cDAQ module appears with Supported Physical Channels this means that the module is able to perform the task. 

Finally selecting a counter, clicking in Next, entering a task name and clicking in Finish will create the task.
