S5 to S7 Conversion issue

Hey guys,

As you can tell i'm trying upgrade S5 CPU (115U) to S7 300
I have one "trouble making" DI card 6ES5 434-7LA12.
I manged to see some PDF's regarding this card and as far as I can tell this DI card uses 2 byes,
the first byte is the actual sensor connected to the card and the 2nd byte is for alarms in FC 2 and also it has a reset wired in the card.
I want to rewrite the logic in different FC instead of the DI card 6ES5 434-7LA12 and thats the part where I need your help.
Can you please advise me what to?

Hey KalleOlsen,
Can u advice me which S7 DI card can replace the S5 DI card?

If the S5 card was used for interrupts and you still need this functionallity, you'll find the input cards that supports interrupt in the HWManager, see the attached picture.
