PXIe-5433 - active light on and reports "The register write command timed out"

Hello,

we use a 5 slot PXI frame to operate PXIe-5433 generator. Since today the active led turns red short time after powering up the frame. Any access to the cards reports "-1074101887" with description is "The register write command timed out". Other cards in this frame are working fine.

Any suggestions on this error?

Best regards,

Tobias
