Features:

  • High-availability processor: CPU 417H role for SIMATIC S7-400H
  • Balanced memory: 15 MB program plus 15 MB data
  • Dedicated synchronization: two interfaces for H-system synchronization modules
6ES7417-4HT14-0AB0 is designed for the paired processing architecture of an S7-400H system.

Its interface set separates engineering and PROFIBUS communication from the two synchronization paths.

Discontinued status makes verified configuration records as important as physical condition when sourcing a spare.

Description
6ES7417-4HT14-0AB0 is the CPU 417H processing module for a SIMATIC S7-400H high-availability system. Its 30 MB memory is divided equally between program and data, providing a defined execution platform for redundancy-oriented process-control projects.

6ES7417-4HT14-0AB0 combines one MPI/DP interface, one PROFIBUS DP interface and two synchronization-module interfaces. This layout supports engineering and fieldbus communication while maintaining the dedicated synchronization path required by an H-system processor pair.

6ES7417-4HT14-0AB0 is no longer available from Siemens. The exact product record refers users to SIOS support ID 59903098 but does not state an orderable successor MLFB, so project compatibility, synchronization hardware and partner-CPU configuration remain central to any sourcing decision.

Technical notes
6ES7417-4HT14-0AB0 is a discontinued CPU 417H with two dedicated synchronization-module interfaces. A replacement must be checked against the partner CPU, firmware, synchronization modules, rack arrangement and validated S7 project; the Siemens support reference is not an orderable successor number, and a connector match alone cannot establish H-system compatibility.

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.
What is the main role of 6ES7417-4HT14-0AB0?
It is a CPU 417H processor for the high-availability SIMATIC S7-400H platform, with dedicated interfaces for synchronization hardware.
How is memory divided in 6ES7417-4HT14-0AB0?
The CPU provides 30 MB in total, divided into 15 MB for program and 15 MB for data.
Which interfaces are built into 6ES7417-4HT14-0AB0?
It has one MPI/DP interface, one PROFIBUS DP interface and two interfaces for synchronization modules.
How should another CPU 417H be evaluated against 6ES7417-4HT14-0AB0?
Siemens does not identify an orderable successor for this exact MLFB on the product page. Treat another CPU 417H as an engineering change and verify the partner CPU, firmware, synchronization modules, rack and validated project before use.
Is there a direct Siemens successor for 6ES7417-4HT14-0AB0?
No orderable Siemens successor MLFB is identified for this article. The published support route is SIOS ID 59903098, so any hardware change still requires an S7-400H engineering review.
What should an RFQ for 6ES7417-4HT14-0AB0 include?
Provide both CPU labels, firmware details, synchronization-module numbers, rack and power-supply layout, project archive status, condition, quantity and outage date.
