False 100ms switching pulse NI9401 outputs?

Hi everyone,

I am facing a very serious problem in my LabVIEW FPGA project, I am using the NI9401 DIO module and in a simple program in FPGA I provide all 8 channels FALSE in a loop, but when I access this FPGA VI from RT VI, when I exit the RT VI I have a unnecessary 100ms pulse on all 8 channels. I am attaching both VI,s images. PLEASE HELP IN THIS REGARDS!

This pulse actually makes a dangerous short circuit in my DC Converter.

With Best Regards,

azy
