Product details

Controller backbone for high-speed lines

The 6ES7515-2UN03-0AB0 is a fail-safe capable PROFINET CPU with 32 kbyte each of input and output process image.

Network resilience that matters

PROFINET runs at full 100 Mbps with MRP Automanager support (IEC 62439-2 Edition 2.0), so if a switch or cable fails mid-shift, the CPU stays online — no production stop to ring an integrator. DCP and DNS are both enabled, which simplifies initial IP assignment and device discovery on a mixed-vendor line. The failsafe logic is programmed in FBD or LAD, both with failsafe instructions built in, and PROFIsafe is supported for safety-related I/O.

Mounting dimensions and sourcing

At 70 mm wide, 147 mm high, and 129 mm deep, the CPU fits DIN-rail mounting with hardware clock, up to 8 CPs/CMs via backplane. IRT unsupported; for isochronous motion see 6ES7515-2TN03-0AB0. Sourced to order; RFQ for BOM.

Frequently asked questions

Does the 6ES7515-2UN03-0AB0 support DCP?

Yes, DCP is listed as supported on this CPU, which allows for dynamic configuration of PROFINET device names and IP addresses.

Does the 6ES7515-2UN03-0AB0 support DNS?

Yes, DNS client is enabled, so the CPU can resolve hostnames on the plant network.

What is the ambient temperature range for this CPU?

The CPU is rated for -40 °C minimum to 70 °C maximum operating temperature, suitable for harsh industrial environments.

Does this CPU support IRT?

No, IRT is not supported on this variant. For isochronous real-time motion control, see the 6ES7515-2TN03-0AB0.

How much I/O process image does it have?

It provides 32 kbyte for inputs and 32 kbyte for outputs, all in the process image.
