Migration notes
- Replacement named on the Rockwell lifecycle page (Engineering Replacement): 1783-CMS20DN (Stratix 5200).
- Rockwell discontinued Stratix 5700 on 01/09/2024 and Stratix 5400 on 30/01/2025. For Stratix 5700, the replacement is the Stratix 5200 catalog number on each lifecycle page; for Stratix 5400 and the 1783-BMS4S2SGL, the Rockwell page lists Engineering Replacement but names no catalog number. Where Layer 3 is needed, TDL proposes Stratix 5800 with Layer 3 firmware (1783-TD002G p.58).
