Features:
- The CPU divides 20 MB of integrated work memory into 10 MB for program code and 10 MB for data.
- An MPI/DP interface and a separate PROFIBUS DP interface carry engineering, controller and distributed-field communication.
- Two synchronization-module positions exchange state information with the partner CPU in an S7-400H pair.
Siemens 6ES7417-4HL04-0AB0 executes the automation program while the paired H-system structure keeps the partner processor synchronized with the current operating state.
The two DP-capable communication paths separate programming and controller access from distributed I/O traffic according to the configured network layout.
Program and data occupy independent 10 MB areas, preventing the user code allocation from being confused with the memory reserved for process data.
The Siemens 6ES7417-4HL04-0AB0 SIMATIC S7-400H CPU 417H may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Processing role in a fault-tolerant pair
- User program: Siemens 6ES7417-4HL04-0AB0 executes the configured control logic for its S7-400H automation station.
- Partner state: The CPU exchanges synchronization data so both processors maintain the operating information required by the H-system.
- Execution rate: The documented processing reference is 0.03ms per 1,000 instructions.
- Connection capacity: Up to 64 communication connections support the configured controller and engineering relationships.
Control and fieldbus paths
- Primary interface: The MPI/DP port carries programming-device, controller or PROFIBUS communication according to its configuration.
- Second bus: A separate PROFIBUS DP interface connects distributed stations without sharing the primary MPI/DP connector.
- Address space: The CPU supports 16 KB of digital input addresses and 16 KB of digital output addresses.
- Network assignment: Each interface must retain the station address and bus parameters defined for Siemens 6ES7417-4HL04-0AB0 in the project.
Program, data and execution resources
- Total capacity: Integrated work memory provides 20 MB for the running automation project.
- Code area: Ten megabytes are reserved for the user program executed by Siemens 6ES7417-4HL04-0AB0.
- Data area: A separate 10 MB allocation stores the process and operating data used by that program.
- Project fit: Program and data usage must each remain within their own allocation rather than being treated as one interchangeable 20 MB pool.
Dual synchronization connections
- Module positions: Two dedicated interfaces accept the synchronization modules used by the S7-400H processor pair.
- Partner link: The installed synchronization paths carry the state exchange between Siemens 6ES7417-4HL04-0AB0 and its paired CPU.
- Separation: Synchronization traffic uses dedicated hardware instead of the MPI/DP or PROFIBUS DP fieldbus connectors.
- Pair consistency: Both CPU positions must follow the H-system hardware and firmware configuration stored in the automation project.
