To read and write data with controls and indicators, drag a shared variable from the Project Explorer window to the front panel of a VI to create a control bound to the shared variable. You also can specify more configuration options or read and write a shared variable in a separate project by completing the following steps.

1. Right-click a front panel object and select Properties from the shortcut menu to display the Properties dialog box for the object.
2. Navigate to the Data Binding page.
3. Select Shared Variable Engine (NI-PSP) from the Data Binding Selection list.
4. Select the shared variable or NI-PSP data item you want to bind the front panel object to.
   1. Click the Browse button to display the Select Source Item dialog box.
   2. Choose from the following options in the Network-Published Source pull-down menu:
      • Select Project Items to bind the front panel object to a shared variable in the current project.
      • Select Network Items to bind the front panel object to a shared variable or other NI-PSP data item in another project.
        Note Your VI will break if you move the shared variable or data item or it becomes unavailable on the network.
   3. Select the shared variable or NI-PSP data item and click the OK button.
5. Under the Access Type pull-down menu of the Data Binding page, choose from the following options to specify how the front panel object interacts with the shared variable or data item:
   • Select Read only to read from the shared variable or data item.
   • Select Write only to write to the shared variable or data item.
   • Select Read/Write to read from and write to the shared variable or data item.
6. Refer to the Troubleshooting Front Panel Data Binding topic for information about ensuring that the connection is successful.
