Alternatives and Future-Proofing

While Distributed Safety V5.6 is stable, it is no longer actively developed by Siemens (maintenance phase only). For new projects, consider:

If you must use Distributed Safety V5.6, plan for a hardware migration to an S7-1500F within the next 5-7 years as S7-300/400 spare parts become scarce.

9. Next steps (practical)
