Adding and Configuring Network DAQ Custom Devices

Complete the following steps to add the cDAQ-9189 and FD-11613/11614 devices as measurements using the Network DAQ Custom Device in the system definition file.

Note If your cDAQ chassis contains measurement types with different acquisition rates, such as voltage input and temperature input, NI recommends that you create separate Network DAQ custom devices.
  1. From the VeriStand Editor, launch System Explorer.
  2. Expand Controller and select Custom Devices in the configuration tree.
  3. Right-click Custom Devices and select National Instruments » Network DAQ.
  4. Use the Network DAQ Custom Device Configuration to configure the following settings:
    Figure 1. Network DAQ Custom Device Configuration


    1. (Optional) Enter a name in the Custom Device Name field, for example cDAQ-9189. The name you specify replaces Network DAQ in the configuration tree.
    2. Enter the MAX hostname in the Ethernet Device Name field. For example, cDAQ9189-1234567, copied from the report created in Creating a System Report.
    3. Set the Acquisition Rate (Hz). NI recommends that you use the default value, which is the Target Rate value set in Configuring the VeriStand Engine (cRIO-9047). Note that this rate is not achievable for temperature measurements.
  5. Click Create.
  6. Enter the total amount of channels of a type available in each device in the Network DAQ channels field of the window that opens. For the cDAQ-9189, use the sum of all channels of a type in all installed modules. The following table lists the channel count for C Series modules and FieldDAQ devices.
    Table 4. C Series Module Channel Count Characteristics
    Type Example Device/Module Channel Count
    AI current HVIL monitor NI-9227 4
    AI voltage Cell/module voltage measurements NI-9224 8
    NI-9225 3
    NI-9228 8
    Thermocouple DUT temperature measurements NI-9212 8
    NI-9213 16
    FD-11613 8
    FD-11614 16
    Note The Battery Test System Software supports only analog input and NI-XNET CAN C Series modules in the cDAQ-9189 chassis. The NI-9860 CAN module must be added as an NI-XNET device, as described in Adding NI-XNET CAN/LIN Devices.
    For each Network DAQ Channel, corresponding placeholder channel information is added.
    Figure 1. Network DAQ Channel Configuration


  7. For every channel, replace the placeholder channel information. NI recommends that you use the recommended naming scheme of <Module_Number>-<Slot>-<Purpose>, introduced in Discovering Network Devices (cDAQ-9189, FieldDAQ Devices). For example, Device/ai4 becomes NI_9213-Mod1-Temperature/ai4.
  8. Click Next.
  9. Select the appropriate DAQmx Acquisition Type and configure the measurement settings for your channels.
  10. Click Create.
  11. Repeat steps 2 through 10 to add either a measurement group for modules with a different acquisition rate, or each additional network device in your system: FD-11613, FD-11614, and so on.
    Note Each instance of the Network DAQ custom device can handle multiple channels of the same device (cDAQ or FieldDAQ), if these use the same acquisition rate. Two Network DAQ custom devices cannot access channels in the same C series module of a device.
  12. Save the system definition file.
