Siemens 6ES7414-5HM06-0AB0

A redundant-control CPU with integrated industrial communication and dedicated synchronization interfaces for SIMATIC S7-400H and S7-400F/FH architectures.

Siemens 6ES7414-5HM06-0AB0 is a SIMATIC S7-400H CPU 414-5H PN/DP central processing unit designed for high-availability S7-400H and safety-related S7-400F/FH architectures. It combines 4 MB of memory with integrated MPI/DP, PROFIBUS DP and PROFINET interfaces, plus two synchronization-module interfaces used in redundant controller configurations. The module suits planned maintenance, installed-base support and controlled replacement projects where system continuity is important. Before ordering, compare the complete part number, CPU firmware, memory-card requirements, rack configuration, synchronization modules, communication interfaces and the original equipment label.

Key Product Information

Redundancy and Communication Path

Interface and Memory Snapshot

The CPU provides one combined MPI/DP interface, one PROFIBUS DP interface, one PROFINET interface and two dedicated interfaces for synchronization modules. Its 4 MB memory is divided equally between program and data capacity. These characteristics support redundant controller engineering, distributed field communication and networked automation, but they do not replace a project-level compatibility review.

Packaging note: Siemens lists packaging dimensions of 23.30 × 30.10 × 6.30 cm. These are packaging dimensions and must not be treated as installation dimensions.

Procurement Gate Checklist

Applications

• High-availability controller maintenance: planned support for installed SIMATIC S7-400H systems.
• Redundant process automation: CPU processing in architectures designed to reduce controller interruption risk.
• Safety-related system projects: use within correctly engineered S7-400F/FH configurations.
• Installed-base replacement planning: controlled model and revision matching during maintenance procurement.
• Industrial network integration: communication through verified MPI/DP, PROFIBUS DP and PROFINET project designs.

Compatibility and Revision Notice

Before ordering, verify the complete part number and suffix, system architecture, supply and interface requirements, hardware revision, firmware and engineering software version, installation dimensions, rack and memory-card requirements, synchronization modules, partner CPU configuration and the original equipment nameplate.
