- Description
The Siemens CPU 414-5H PN/DP (6ES7414-5HM06-0AB0) is a fault-tolerant central processing unit for SIMATIC S7-400H and S7-400F/FH systems, with 4 MB of work memory split 2 MB program and 2 MB data. Five interfaces cover MPI/DP, a dedicated DP port, PROFINET, and two synchronization module ports for redundant CPU pairing.

Selection Notes
Against the 412-5H, this CPU quadruples work memory to 4 MB and doubles the connectable-OP count to 63, while keeping the same five-interface layout, MPI/DP, DP, PROFINET, and two synchronization ports for redundant pairing. Pick it when a fault-tolerant S7-400H station, or a safety program on S7-400F/FH, needs more than the 412-5H's 1 MB and 47-OP ceiling. Processing time also drops to 18.75 ns typical from 31.25 ns, cutting scan time on identical logic.
