VISA read and print on front panel

Hello,
i have a program that read data from VISA. There are 12 indicators that are moving depending data read and everyone of this has a LED. When one of this is out from the acceptable range, the own LED become red. I want to print on front panel the name of the LED that are red. I tried in this mode but the string in the indicator in the front panel flashes . The program is enclosed in a while loop serving for the reading from VISA. How can i do?
Thanks in advance
