Note
If the DI/DQ interfaces X122, X132 and X142 are operated partially as DI and partially as DQ
(mixed operation), then the DI must be operated with the same power supply as the NCU
module power supply X124.
This applies to:
• 6FC5317-5AA00-0AA0, hardware versions FS: A to E
• 6FC5317-5AA00-0AA1, is not aected.
