When I ammonitoring in a FC, the digital outputs go to zero for a short time in the same frequency the monitoring is working. Itscares me a lot.This effect only excist with the monitoring (glasses) on and not in all FC's, FB's.I have seen it whenI was monitoring with MPI and with a CP343-1ethernet card. There is no error in the CPU, a small processorload and the monitoring time was default 20%, no consistency error in the program.

The 315-2AG10 for example had an issue with firmware V2.61 and 2.62 that could lead to a corruption of theRLO during online monitoring (whichwoudl neatly explainyour problem, see HERE for more on this).
