More Information

Overview Manuals Sync Links Memory Split Bus Paths H Pairing

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.
Description
Siemens 6ES7414-4HR14-0AB0 is a CPU 414-4H PG central processor for the SIMATIC S7-400H platform. It runs the configured control program while participating in the coordinated operation of an H-system processor pair.

A total of 12 MB of working memory in 6ES7414-4HR14-0AB0 is divided into 2 MB for program code and 10 MB for data. This fixed partition separates executable blocks from the larger area assigned to runtime values.

Communication on 6ES7414-4HR14-0AB0 is divided among one MPI/DP interface, one additional PROFIBUS DP interface, and two connections for synchronization modules. The fieldbus ports handle configured controller and device traffic, while the synchronization paths connect the redundant CPU partners.

The 6ES7414-4HR14-0AB0 variant is identified as the energy-sector CPU 414-4H PG configuration. Its V4.5.3 firmware baseline and dedicated synchronization interfaces distinguish it from other CPU 414-4H order numbers.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why must both synchronization paths be planned for Siemens 6ES7414-4HR14-0AB0?
The two dedicated connections on Siemens 6ES7414-4HR14-0AB0 link the paired H CPUs and are separate from the fieldbus interfaces.
How is working memory arranged inside Siemens 6ES7414-4HR14-0AB0?
Siemens 6ES7414-4HR14-0AB0 assigns 2 MB to program code and 10 MB to data, so each section has its own capacity boundary.
Which interface should carry a second DP segment on Siemens 6ES7414-4HR14-0AB0?
Use the dedicated DP interface of Siemens 6ES7414-4HR14-0AB0 when the MPI/DP connector is assigned another network role.
What distinguishes Siemens 6ES7414-4HR14-0AB0 from another CPU 414-4H order number?
The complete Siemens 6ES7414-4HR14-0AB0 code identifies the PG energy-sector version with 12 MB memory and its documented V4.5.3 baseline.
Can the sync connectors on Siemens 6ES7414-4HR14-0AB0 be treated as PROFIBUS ports?
No. Siemens 6ES7414-4HR14-0AB0 reserves those two connectors for synchronization modules; MPI/DP and DP traffic use separate interfaces.
