Product details

The 6ES7512-1SK01-0AB0 is a Siemens SIMATIC fail-safe CPU with a 32 kbyte I/O process image coverage – all inputs and outputs are in the image, so no need to worry about addressing holes for standard I/O. It supports PROFIsafe V2.4 and V2.6, FBD/LAD/SCL/STL/GRAPH programming including fail-safe extensions, so safe logic can be mixed with standard logic in the same CPU. Network interfaces are PROFINET with IRT, MRP, and MRPD, plus MODBUS TCP, HTTP/HTTPS for web server, and DNS/DCP for discovery and configuration – ready for line integration without an extra comm module. Onboard hardware clock with I&M data up to I&M3 supports consistent time-stamping and asset tracking across the plant network.

Width 100 mm, height 117 mm, depth 75 mm – fits the standard single-width CPU format. Panel cutout matches the existing rail mount; no extra DIN-rail bracket needed. Forcing of outputs is supported in the non-fail-safe part of the program, giving the commissioning engineer override capability without disabling safety logic.

Frequently asked questions

How does this CPU handle network configuration on a PROFINET network?

It supports DCP (Discovery and Configuration Protocol) for automatic IP address assignment and DNS for hostname resolution, so you can drop it onto an existing managed network without a static IP pre-set.

What safety protocol does the CPU support?

PROFIsafe V2.4 and V2.6, allowing connection to fail-safe I/O and meeting SIL requirements for safety applications.

Can the CPU handle motion control with isochronous real-time?

Yes, it supports PROFINET IRT and MRPD, enabling isochronous real-time communication for synchronized motion axes.
