Product details

CPU module for S7-1200 – process image and networking

The 6ES7512-1DK00-0AB0: It supports MRP redundancy manager (up to 50 devices in the ring) and IRT with MRPD, so you can build a deterministic PROFINET ring with backup path switching. Programming-language support spans LAD, FBD, SCL, STL, GRAPH, and the integrated PID controllers cover temperature and valve loops – no separate function block licensing needed for those. The hardware clock is present, and HTTP/HTTPS allow standard and user-defined web pages for diagnostics without an extra HMI.

DIN rail dimensions and panel layout

Cable clearance allowances: the depth includes the module body but leaves the front interface and top/bottom wiring channels accessible per Siemens panel-layout guidelines.

Frequently asked questions

Does 6ES7512-1DK00-0AB0 support DCP for PROFINET configuration?

Yes, it supports DCP (Discovery and Configuration Protocol) for automatic addressing and device identification on the network.

Does this CPU support FBD programming?

Yes, FBD (Function Block Diagram) is one of the supported languages, along with LAD, SCL, STL, and GRAPH.

What does the I2t rating of 0.14 A²·s mean for circuit protection?

It represents the thermal withstand energy of the device's internal supply input. Use this value to coordinate upstream fuse or MCB selection to avoid nuisance tripping during inrush or short events.

Can this CPU act as MRP redundancy manager?

Yes, it can function as both MRP redundancy manager and client, supporting a ring of up to 50 devices.
