OK, you had a problem, came to the Forum to ask for help, we gave you suggestions and tried to help, you got a solution that worked.
Please "give back to the Community" by sharing the "solution" that worked for you. Especially if some of our suggestions led you to the "solution". I recommend attaching LabVIEW VIs (or a small demonstration Project) that illustrates how you've implemented the scheduled FPGA action when communication is lost.
