03System Role
Controller Function
- Operates as one controller of a redundant S7-400H CPU pair.
- Coordinates central modules and distributed devices over the configured PROFINET and PROFIBUS networks.
- Maintains synchronization and defined switchover behavior with the compatible partner CPU.
- Provides standard and, where engineered, fail-safe processing for process-automation applications.
- Uses the memory card, firmware, H parameters and STEP 7 project as controlled parts of the system configuration.
Key Capabilities
- High-availability CPU design supports synchronized paired operation in an S7-400H system.
- Four megabytes of work memory are divided equally between program and data areas.
- Integrated PROFINET, MPI/DP and DP interfaces provide multiple automation-network paths.
- Two synchronization-module interfaces support the documented H-system coupling.
- Flash or RAM memory cards up to 64 MB support the configured load-memory requirement.
- The CPU can support an engineered S7-400F/FH solution when the required safety software, hardware and validation are applied.
04Compatibility
- Use a compatible CPU partner with matching article requirements, hardware status and firmware V6.0.
- Verify both synchronization modules, fiber connections, H parameters and redundant rack arrangement.
- Use STEP 7 V5.5 SP2 with HF1 or a later officially supported engineering environment.
- Confirm MPI/DP, separate DP and PROFINET addresses, bus parameters, device names and network redundancy.
- Match the flash or RAM memory card to the project and the documented maximum capacity.
- For F/FH applications, retain every safety license, F-I/O parameter, signature, proof-test record and acceptance document.
05Applications
- High-availability process-control stations using paired CPU 414-5H controllers.
- S7-400H systems combining PROFINET and PROFIBUS DP distributed I/O.
- Engineered S7-400F/FH installations requiring redundant and fail-safe processing.
- Service replacement with verified firmware, partner CPU, synchronization modules and memory card.
- Process plants requiring controlled CPU switchover and redundant communication paths.
- Lifecycle planning for active S7-400H systems where project continuity and spare compatibility are critical.
