More about selecting SIMATIC S7-1500 CPUs parts

SIEMENS SIMATIC S7-1500 central processing units

The CPU is the central controller of the SIMATIC S7-1500 system. It executes the user program, processes input and output data and provides communication with distributed I/O, HMI panels, drives, other PLCs and higher-level systems.

The S7-1500 range includes processors for applications of different complexity – from smaller machines to larger production systems, safety applications and motion control tasks.

Standard CPUs

Standard CPU 1511, 1513, 1515, 1516, 1517 and 1518 processors are designed for standard and high-performance automation tasks. They differ in processing performance, work memory and communication interfaces.

Compact CPU 1511C / 1512C

Compact processors combine the CPU with integrated digital and analog inputs and outputs and selected technology functions.

Fail-safe F CPUs

S7-1500F fail-safe processors are designed for standard control and safety functions within one system using PROFIsafe.

Technology CPUs T / TF

S7-1500T technology processors provide extended motion control capabilities. TF versions combine technology and safety functions.

How to choose the right S7-1500 CPU?

When replacing an existing CPU, the safest method is to use the complete SIEMENS order number. When selecting a different processor, check in particular:

processing performance and required work memory,
number and type of communication interfaces,
requirements for PROFINET or PROFIBUS DP,
whether a standard, compact, F, T or TF processor is required,
required technology and Motion Control functions,
HW and FW version of the existing CPU,
compatibility with the project and TIA Portal version.

Typical SIMATIC S7-1500 CPUs

Order number	CPU	Type / application
6ES7511-1AK01-0AB0	CPU 1511-1 PN	Standard CPU with PROFINET interface
6ES7513-1AL01-0AB0	CPU 1513-1 PN	Higher-performance standard CPU with PROFINET
6ES7515-2AM01-0AB0	CPU 1515-2 PN	CPU with two PROFINET interfaces
6ES7516-3AN02-0AB0	CPU 1516-3 PN/DP	CPU with PROFINET and PROFIBUS DP
6ES7517-3FP01-0AB0	CPU 1517F-3 PN/DP	Fail-safe CPU
6ES7516-3TP10-0AB0	CPU 1516T-3 PN	Technology CPU for advanced Motion Control applications

CPU 1510SP and 1512SP for ET 200SP

The S7-1500 family also includes CPU 1510SP and CPU 1512SP processors for the ET 200SP distributed I/O system. When replacing a CPU, we recommend comparing the complete order number, CPU version and project configuration.

New and refurbished CPUs from stock

For current SIMATIC S7-1500 processors, we primarily check the availability of a new original SIEMENS CPU. We use an extensive European warehouse network with more than 900,000 industrial spare parts.

This also enables us to source refurbished, older, obsolete or hard-to-find CPUs. If you cannot find a specific order number in the e-shop, send it to us and we will prepare a quotation with price and delivery time.

Repairs of SIEMENS SIMATIC S7-1500 CPUs

If you have a faulty S7-1500 CPU, you can send it to us for diagnostics and repair. Repairs are carried out in specialised repair centres in Europe with which we have established long-term cooperation.

These repair centres specialise in industrial electronics and repaired processors are functionally tested before being returned to the customer.

SIPLUS S7-1500 CPUs

Selected SIPLUS S7-1500 versions are available for applications operating under more demanding environmental conditions. You can find them in a separate SIPLUS CPU subcategory.

Frequently asked questions

Is the CPU order number enough for an enquiry?

Yes. Ideally, send us the complete SIEMENS order number from the nameplate, for example 6ES7515-2AM01-0AB0, and the required quantity. We will prepare a quotation with price and delivery time, usually within 1 hour.

Can you supply a CPU that is not listed in the e-shop?

Yes. We also check other processors in European warehouses. Send us the order number and we will prepare a quotation based on current availability.

Do you arrange repairs of S7-1500 CPUs?

Yes. Send the faulty CPU to FOXON. We will arrange diagnostics, repair and subsequent functional testing at a specialised European repair centre with which we have long-term cooperation.

Can I replace an S7-1500 CPU with another type?

Not always. Processing performance, work memory, communication interfaces, safety and technology functions, HW and FW version and compatibility with the TIA Portal project must be checked.

What is the difference between CPU, F-CPU, T-CPU and TF-CPU?

A standard CPU is designed for standard automation tasks. F-CPU adds safety functions, T-CPU provides extended technology and Motion Control functions, while TF-CPU combines technology and safety functions.

Is the firmware version important when replacing a CPU?

Yes. When replacing a processor, the order number, CPU HW and FW version and compatibility with the existing project and TIA Portal version should be checked.
