Lifecycle status and what it means for procurement
The 6ES7398-8AA01-8AB0: Because this is a brochure, not a production part, the eol_hot status means Siemens no longer prints or distributes this specific migration guide. Sourcing runs through independent surplus channels; quantities are confirmed at RFQ.
What this document covers
For a controls integrator or site electrical engineer planning a legacy S5-to-S7 migration, this brochure provides the high-level migration path overview. It is not a wiring manual or programming guide — it is the introductory sales and concept document.
