Issue Details

I have used Read/Write Control in my LabVIEW Real-Time code to access the controls and indicators on the FPGA front panel, but I cannot select individual cluster elements, only the whole cluster, as shown below:

Solution

This issue occurs when Open FPGA VI Reference is set to run in a Dynamic mode. To select individual FPGA VI cluster elements, follow these steps:
 
1. Right-click Open FPGA VI Reference and select Configure Open FPGA VI Reference
2. Disable the Dynamic Mode by unchecking the relevant box


After this, the individual cluster elements should be available, as seen below:
