You can use FPGA I/O name controls to create reentrant subVIs with configurable I/O items. When you use an FPGA I/O control as an input on a subVI, the input accepts only I/O items that support a superset of the methods and properties you enable for the FPGA I/O control. All enabled methods must match in name, and their parameters must match in name, order, and data type. All enabled properties must match in name and data type.

Complete the following steps to configure the FPGA I/O name control using the Configure FPGA I/O Name Control Type dialog box.

  1. Right-click an FPGA I/O control or constant and select Configure I/O Type from the shortcut menu to display the Configure FPGA I/O Name Control Type dialog box.
  2. Select an FPGA I/O item from the I/O Items list that supports all the methods and properties you plan to use with the FPGA I/O control. The methods and properties of the I/O item you select appear in the I/O Item Type list.
  3. Click Replace All to copy all the methods and properties from the I/O Item Type list to the I/O Name Control Type list. You cannot move individual I/O item types to the I/O Name Control Type box.
  4. Click Remove to remove methods and properties from the I/O Name Control Type list that you do not want to require of I/O items passed to the control. To make the control broadly reusable, remove any resource-specific methods and properties that you do not want to use with the FPGA I/O control. You can click an item in the I/O Name Control Type list and read about the item in the I/O Name Control Type Details section.
  5. Click OK to close the dialog box.
