- Description
Fail-safe function blocks distinguish the Siemens CPU 414F-3 PN/DP (6ES7414-3FM07-0AB0) from the standard 414-3: it is a SIMATIC S7-400 CPU built for safety-related SIMATIC S7-400F/FH programs, with 4 MB of work memory (2 MB program, 2 MB data) across three interfaces, MPI/DP on X1, Ethernet/PROFINET on X5, and a plug-in IF 964-DP port.

Selection Notes
Choose the F-3 over the standard 414-3 when the program includes safety functions written with F-blocks for an S7-400F or S7-400FH station; the underlying hardware, memory, and three-interface layout are otherwise identical. Only the startup-OB count differs in the verified data, two on this CPU against three on the non-safety 414-3, reflecting the more constrained startup sequence a safety-rated CPU runs. Where no F-blocks are needed, the standard 414-3 PN/DP is the simpler and functionally equivalent pick.
