FAQ

Q1: What is the primary function of the 6ES7518-4JP00-0AB0?

A: It is a fail-safe high-availability CPU for the SIMATIC S7-1500H platform. It handles both standard automation logic and safety-related functions up to SIL 3/PL e while providing redundancy for maximum system uptime.

Q2: Is this product still available?

A: Siemens has announced a product phase-out effective October 1, 2025. Availability depends on remaining stock at authorized distributors and industrial automation suppliers.

Q3: What are the key memory specifications?

A: The CPU provides 9 MB work memory for program and 60 MB work memory for data. A SIMATIC Memory Card (max. 32 GB) is required for load memory and is not included.

Q4: What communication interfaces does this CPU have?

A: It features three PROFINET interfaces (one with a 2-port switch) and two H-SYNC interfaces for redundant synchronization.

Q5: Does this CPU support safety functions?

A: Yes. It supports PROFIsafe and is certified to SIL 3 (IEC 61508) and PL e (ISO 13849-1). Standard and safety programs can run simultaneously on the same CPU.

Q6: What software is required for programming?

A: Configuration and programming require TIA Portal V17 or higher. For safety programming, an additional Safety Advanced license is needed.

Q7: What is the difference between the CPU 1518HF-4 PN and standard S7-1500 CPUs?

A: The "HF" designation indicates High Availability + Fail-safe capability. Standard CPUs do not offer built-in redundancy or integrated safety functionality.

Q8: What is the power supply requirement?

A: The CPU operates on 24 V DC with a permissible range of 19.2 to 28.8 V DC.
