Features:
- Provides the CPU 414-4H PG processing role in an S7-400H station.
- Separates 12 MB of memory into program and data areas.
- Uses two dedicated interfaces to synchronize the redundant processor pair.
The CPU places program execution, fieldbus communication, and H-system synchronization in one S7-400H processor module.
An MPI/DP port and a separate DP port let the hardware project assign two fieldbus paths without using the synchronization connectors.
The energy-sector order number identifies a defined memory split and firmware baseline that must be matched during configuration review.
The Siemens 6ES7414-4HR14-0AB0 CPU 414-4H PG Central Processing Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Connecting the redundant partners
- Dual paths: Two synchronization-module interfaces link the paired CPUs.
- Dedicated role: Synchronization traffic remains separate from the MPI/DP and DP networks.
- Partner alignment: Both processors require a matching H-system configuration.
- Module boundary: The sync modules occupy their specified CPU connections rather than fieldbus ports.
Separating code from runtime data
- Program area: Two megabytes are reserved for executable program blocks.
- Data area: Ten megabytes hold the values used while the control program runs.
- Fixed allocation: The two areas form the documented 12 MB working-memory total.
- Project check: Block and data requirements must fit their respective memory sections.
Assigning communication duties
- MPI/DP: The first interface can carry MPI services or a configured PROFIBUS DP segment.
- Additional DP: A second interface provides a separate PROFIBUS DP connection.
- Network project: Station addresses and bus roles are stored in the hardware configuration.
- Port separation: Neither fieldbus connector replaces the two H-system synchronization paths.
Forming the S7-400H processor pair
- CPU partner: A corresponding H CPU forms the second processing side of the redundant station.
- Matched project: Both CPU sides use the same planned H-system structure.
- Program coordination: Synchronization connections keep the paired processors aligned during operation.
- Order identity: The full 6ES7414-4HR14-0AB0 suffix identifies the CPU 414-4H PG energy-sector variant.
