Siemens 6ES7518-4JP00-0AB0 SIMATIC S7-1500H CPU 1518HF-4 PN
A high-availability and fail-safe S7-1500H controller with large work memory, three PROFINET interfaces and two dedicated H-SYNC interfaces.
Product Identification
6ES7518-4JP00-0AB0 is the Siemens CPU 1518HF-4 PN for the SIMATIC S7-1500H high-availability controller family. It combines 9 MB of program work memory with 60 MB of data work memory.
The CPU provides three PROFINET interfaces and two dedicated H-SYNC interfaces. A SIMATIC Memory Card is required, and Siemens lists the article in active PM300 status with phase-out announced from 1 October 2025.
The HF controller identity, partner CPU, H-SYNC topology, safety project and memory card form one controlled replacement record.

Functions
Run a fail-safe automation project
Executes the configured safety and standard program within the approved S7-1500H architecture.
Maintain high availability
Uses the paired CPU and H-SYNC links for synchronized controller operation.
Separate network responsibilities
Three PROFINET interfaces support documented plant, field and engineering communication paths.
Applications
High-availability process control
Use where the approved S7-1500H architecture and fail-safe project are required.
Large controller projects
Review the 9 MB program and 60 MB data memory against the archived project.
Lifecycle-controlled spare planning
Include the announced phase-out status in long-term inventory and migration planning.

FAQ
What makes 6ES7518-4JP00-0AB0 different from a standard S7-1500 CPU?
It is an HF controller with high-availability synchronization, fail-safe project support and dedicated H-SYNC interfaces.
What must accompany a 6ES7518-4JP00-0AB0 request?
Provide both CPU labels, firmware, memory card, safety signature, project version and H-SYNC topology.
How many PROFINET interfaces are published for 6ES7518-4JP00-0AB0?
The product record lists three PROFINET interfaces, with an integrated two-port switch on the first.
Why is lifecycle status relevant for 6ES7518-4JP00-0AB0?
Siemens has announced phase-out, so spare planning and an approved migration path should be documented.
What proves 6ES7518-4JP00-0AB0 is accepted after service?
Record synchronization, safety status, communications and the approved high-availability test result.
