The VeriStand Engine is the non-visible execution mechanism that controls the timing of the entire system as well as the communication between the target and the host computer.

Complete the following steps to configure the VeriStand Engine.

  1. From the VeriStand Editor, launch System Explorer by completing either of the following:
    • Double-click the system definition file (.nivssdf) in the Project Files pane of the VeriStand Editor.
    • Launch the system definition file from Project Files and click Configure.
  2. Select Controller in the configuration tree.
  3. Specify the following settings on the Controller Configuration page to configure the timing of the VeriStand Engine and communication between the controller and the host computer.

    1. Leave name set to Controller.
    2. In the Operating System list, select Linux_x64.
    3. Specify the IP Address of your cRIO-9047, copied from the report created in Creating a System Report.
    4. Specify a Username if you set up a system user login for the cRIO-9047 in Discovering the cRIO-9047 Controller.
    5. Specify a Password if you set up a system password for the cRIO-9047 in Discovering the cRIO-9047 Controller.
    6. In the FPGA/Scan interface mode list, select Scan Mode. This sets the NI Scan Engine to Scan Interface mode.
    7. Set the Target Rate to 1000. This specifies the rate at which you can take measurements or trigger alarms. NI Scan Engine cannot exceed 1,000 Hz, however, a high target rate may affect CPU utilization.
  4. Save the system definition file.
