End-of-life hot — what that means for your BOM line
The 6ES7322-1FF81-0AA0: If you are holding a BOM that calls out this module, the clock is running: source now or plan a migration path to a current S7-1200 or S7-1500 digital output module, which will require a different backplane and wiring scheme.
S7-300 backplane fit and deployment context
The module snaps onto the S7-300 DIN-rail mounting rail and connects to the backplane bus via the standard S7-300 front connector — no special adapter required.
