- Description
The Siemens 6ES7518-4JP00-0AB0 is a SIMATIC S7-1500H CPU 1518HF-4 PN, a redundant fail-safe central processing unit with 9 MB of program memory and 60 MB of data memory. It runs in pairs synchronized over H-SYNC on its 4th and 5th interfaces, alongside three PROFINET ports, and requires a SIMATIC Memory Card per CPU.

Selection Notes
The H in this CPU's family marks it for redundant operation: two CPU 1518HF-4 PN units run in a synchronized pair over the dedicated H-SYNC fiber-optic interfaces (4th/5th), so a single CPU fault does not stop the process, unlike a standard non-redundant S7-1500 CPU. The trailing F in the product designation adds fail-safe capability on top of that redundancy, so safety-rated shutdown logic can run on the same redundant pair instead of a separate F-CPU. Against this, the lower connectable-IO-device count (256, versus 512+ on non-H CPUs) and smaller rack (9 modules) reflect that H-system slots are reserved for the synchronization and communication modules the redundant pair needs; applications without a redundancy requirement fit better on a standard S7-1500F CPU.
Applications
Continuous processes where an unplanned CPU stop is unacceptable, such as process lines or utilities where the redundant pair takes over control without interrupting the running program.
