SIMATIC S7-1500
Modular Siemens advanced controller with standard, compact, fail-safe, technology and redundant CPUs, up to 162 MB of work memory and bit instruction times down to 0.3 ns
Price and delivery time are given after a technical review.
SIMATIC S7-1500 is Siemens' advanced controller for machines and production lines with high demands on speed and communication. It is modular and scalable: CPUs, system power supplies, signal modules, technology modules (such as counting) and communication modules are combined centrally or in distributed configurations. The system is rated IP20 and intended for installation in a control cabinet.
In the new CPU generation (firmware V4.1) work memory ranges from 1.8 MB in the CPU 1511-1 PN to 162 MB in the CPU 1518-3 PN, and the bit instruction time from 6 ns down to 0.3 ns (table in the CPU 1511-1 PN manual, edition 01/2026). The CPUs have a display and at least one PROFINET interface with a two-port switch.
A PROFINET interface with IRT is built into the CPU; Siemens names PROFINET, Industrial Ethernet and OPC UA. The security-by-default concept includes authorization levels, block protection and communication integrity.
Standard and fail-safe control run in one system with one engineering. PROFIsafe devices connect over PROFIBUS and PROFINET, and the data sheet of the CPU 1511F-1 PN states SIL 3 (IEC 61508) and PL e (ISO 13849-1). Every S7-1500 CPU supports motion control without additional modules.
Configuration, programming and diagnostics are done in TIA Portal. According to the data sheets the new CPUs with firmware V4.1 are integrated from STEP 7 V21, and CPUs with firmware V3.0 from V18.
The family is in production. Some previous-generation CPU codes (firmware V2.9, such as 6ES7511-1AK02-0AB0 and 6ES7515-2AM02-0AB0) are headed 'spare part' in Siemens' data sheets, and the new-generation codes have taken their place.

First pick the class from the need: standard, compact (with integrated I/O), F for safety, T for advanced motion or R/H for redundancy. Then compare program and data memory, speed and the number of network interfaces; for example the CPU 1511-1 PN has one PROFINET interface and 300 KB of program memory, while the CPU 1518-3 PN has three interfaces and 12 MB.
Yes, with F-type CPUs. The data sheet of the CPU 1511F-1 PN states SIL 3 to IEC 61508 and PL e to ISO 13849-1. PROFIsafe modules connect over PROFINET and PROFIBUS, and mixed operation of standard and fail-safe modules is supported.
It depends on the CPU firmware. According to the data sheets the new CPUs with firmware V4.1 are integrated from STEP 7 V21, and CPUs with firmware V3.0 from V18. Older TIA Portal versions can configure the CPU as the previous-generation article; the details are in each CPU manual.
Siemens offers R-type CPUs (1513R-1 PN and 1515R-2 PN) and H-type CPUs (1517H-3 PN, 1517H-4 PN and 1518HF-4 PN) for this. The H CPUs have H-SYNC interfaces. The layout and network requirements are in the S7-1500R/H redundant system manual.
Siemens' migration guide (09/2015) maps the CPU 312 and 314 to the CPU 1511, the CPU 315-2 PN/DP to the CPU 1515-2 PN, the CPU 317-2 PN/DP to the CPU 1516-3 PN/DP and the CPU 319-3 PN/DP to the CPU 1517-3. The guide quotes the codes of that time; take the current code of each CPU from the table above or the Industry Mall.
