Product details

Failsafe CPU for safety-critical lines

The Siemens 6ES7515-2FN03-0AB0 is a failsafe CPU — it runs standard and safety logic on the same processor, with LAD and FBD both supporting failsafe blocks. PROFIsafe V2.4/V2.6 is built in, so you can wire safety I/O directly to the backplane without a separate safety controller. The process image handles 32 kbyte each for inputs and outputs — enough to map a medium-sized safety zone with distributed I/O racks without forcing a second CPU.

Network redundancy and media protocols

Supports MRP Automanager per IEC 62439-2 Edition 2.0, plus MRPD — but MRPD requires IRT, which this CPU does not offer natively. If you need isochronous real-time motion, you will need a different CPU variant. Ethernet stack is full: TCP/IP, UDP, DHCP, DNS, LLDP, SNMP, HTTP/HTTPS with custom user pages, and MODBUS TCP. No fieldbus module needed for basic plant-floor connectivity.

DIN-rail footprint and expansion

Up to 8 communication modules (PROFIBUS, PROFINET, Ethernet) can be inserted via the left-side expansion slots. The backplane supplies power; no separate CM power supply needed.

Frequently asked questions

Is the Siemens 6ES7515-2FN03-0AB0 a failsafe CPU?

Yes. It supports failsafe LAD and FBD programming, and integrates PROFIsafe V2.4/V2.6 for safety I/O communication. Standard and safety logic run on the same processor.

What is the program and data memory of 6ES7515-2FN03-0AB0?

The process image is 32 kbyte each for inputs and outputs. The CPU uses an external SIMATIC Memory Card for user program and data storage — the card size determines the available memory.

Can 6ES7515-2FN03-0AB0 be used with PROFINET IRT?

No. This CPU does not support IRT natively. It supports MRP and MRPD, but MRPD requires IRT — so MRPD is not available on this model. For isochronous real-time applications, select a CPU with IRT support.

What is the difference between 6ES7515-2FN03-0AB0 and 6ES7515-2AN03-0AB0?

The 2FN03-0AB0 is the failsafe variant with PROFIsafe built in. The 2AN03-0AB0 is the standard (non-failsafe) CPU. Both share the same form factor and process image size, but the failsafe version adds safety logic execution and PROFIsafe communication.

How can I order the Siemens 6ES7515-2FN03-0AB0?

This CPU is sourced to order against your RFQ. Availability and pricing are confirmed at quote time.
