Troubleshooting Front Panel Data Binding

When you bind a front panel control or indicator to a shared variable at edit-time, a small transparent indicator appears next to the front panel object. When you run the VI, if the connection to the Shared Variable Engine is successful, the indicator turns green, as shown in the following figure.

If the connection is not successful, the indicator turns red. A status message also appears if you move the cursor over the indicator.

Note��You can hide this indicator using the following methods: Right-click the front panel object and select Visible Items�PSP LED from the shortcut menu. Use the Data Binding:LED Visible property to hide the indicator programmatically.

If you receive errors when attempting to read or write data from the front panel, investigate the following possible causes:

• Ensure that you have deployed the shared variable.
• Ensure that the device for the target on which the shared variable resides is functional and supports front panel data binding. Refer to the documentation for the LabVIEW modules and toolkits you have installed to determined whether they support front panel data binding.
