Siemens 6ES7412-2XK07-0AB0 CPU 412-5H

High-Availability Redundant CPU for SIMATIC S7-400 H-Systems

The Siemens 6ES7412-2XK07-0AB0 is a fault-tolerant CPU designed for mission-critical S7-400 H-systems requiring zero downtime. This CPU 412-5H delivers seamless hot-standby redundancy with automatic failover, ensuring continuous operation in power generation, oil & gas, and pharmaceutical applications.

🛡️ Why Redundant CPUs Matter

In critical infrastructure, a single CPU failure can cost millions in downtime. The CPU 412-5H eliminates this risk:

  • ✅ Hot-Standby Redundancy – Dual CPUs run in parallel, instant failover on fault
  • ✅ Bumpless Switchover – Zero process interruption during CPU changeover
  • ✅ Online Module Replacement – Swap CPUs without stopping production
  • ✅ Synchronized Operation – Both CPUs execute identical programs in lockstep
  • ✅ Diagnostic Monitoring – Continuous health checks detect faults before failure

🔄 How H-System Redundancy Works

Dual CPU Architecture

The CPU 412-5H operates in pairs within an S7-400 H-system:

  • Primary CPU: Actively controls the process
  • Standby CPU: Mirrors primary CPU state in real-time
  • Fiber Optic Link: Synchronizes CPUs via redundant fiber cables
  • Automatic Failover: Standby becomes primary within 100ms if fault detected

Fault Scenarios Covered

  • ✅ CPU hardware failure (processor, memory, power supply)
  • ✅ Rack power loss (redundant power supplies required)
  • ✅ Communication errors (MPI, Profibus, Ethernet)
  • ✅ I/O module faults (with redundant I/O configuration)
