🔄 How H-System Redundancy Works
Dual CPU Architecture
The S7-400H system uses two identical CPU 412-5H modules operating in parallel:
- Primary CPU: Actively controls the process and updates outputs
- Standby CPU: Mirrors primary CPU state, ready to take over instantly
- Synchronization: Fiber optic sync modules ensure both CPUs maintain identical states
- Automatic Failover: If primary CPU fails, standby becomes active within 100ms
System Components Required
- 2× CPU 412-5H (6ES7412-1XJ07-0AB0) - this product
- 2× Sync modules (6ES7960-1AA06-0XA0) - fiber optic synchronization
- 2× Power supplies (redundant PS 407)
- 2× UR2-H racks (6ES7400-2JA00-0AA0)
- Redundant I/O modules (SM 421/422/431/432 with -5H suffix)

📊 H-System vs. Standard S7-400
| Feature | S7-400H (This CPU) | Standard S7-400 |
|---|---|---|
| Availability | 99.99% (4 nines) | 99.9% (3 nines) |
| Downtime/Year | ~53 minutes | ~8.8 hours |
| CPU Redundancy | ✅ Dual CPUs with auto-failover | ❌ Single CPU |
| Hot-Swap CPUs | ✅ Yes (without process stop) | ❌ No (requires shutdown) |
| I/O Redundancy | ✅ Optional (with -5H I/O modules) | ❌ Not supported |
| System Cost | 💰💰💰💰 High (2× hardware) | 💰💰 Standard |
| Programming Complexity | ⭐⭐⭐ Moderate (H-specific blocks) | ⭐⭐ Standard |
| Best For | Mission-critical, 24/7 operations | Standard automation, scheduled maintenance OK |
💰 Return on Investment Analysis
Cost of Downtime (Example: Refinery)
- Production Loss: $1,000,000/hour (typical refinery)
- Standard S7-400 Downtime: 8.8 hours/year = $8.8M loss
- S7-400H Downtime: 0.88 hours/year = $880K loss
- Annual Savings: $7.92M
H-System Investment
- Additional Hardware Cost: ~$50K (2× CPUs, sync modules, racks)
- Payback Period: <3 days of avoided downtime
- 10-Year ROI: $79.2M savings - $50K investment = 1,584% ROI
Conclusion: For high-value processes, H-system redundancy pays for itself in days, not years.

❓ FAQ
Q: Can I use this CPU in a standard (non-redundant) S7-400 system?
A: No, CPU 412-5H requires H-system configuration with dual CPUs and sync modules. For standard systems, use CPU 412-2 instead.
Q: What happens if one CPU fails?
A: The standby CPU automatically becomes active within 100ms. The process continues without interruption. Replace failed CPU during operation.
Q: Do I need redundant I/O modules?
A: Optional. Use standard I/O for cost savings, or -5H I/O modules for full redundancy including field wiring.
Q: Can I upgrade from standard S7-400 to H-system?
A: Yes, but requires significant hardware changes (dual racks, CPUs, sync modules). Consult Siemens for migration planning.
Q: What's the maximum distance between redundant racks?
A: Up to 10 km using fiber optic sync modules. Longer distances require special engineering.
Q: Is this CPU compatible with S7-1500 systems?
A: No, S7-400H and S7-1500 are separate platforms. For new projects, consider S7-1500R (redundant) as modern alternative.
