The Siemens 6AG1511-1FK01-2AB0 is an ET 200SP CPU that handles PROFINET IRT and MRP redundancy for up to 50 devices in the ring, with integrated PROFIsafe for safety-rated motion sequences. Programming options include FBD, LAD, SCL, STL, and GRAPH, with failsafe libraries built into the FBD and LAD editors. The CPU runs on MODBUS TCP, UDP, and HTTP/HTTPS for web-based diagnostics.
Mounts on a 35 mm-wide ET 200SP base unit. Overall dimensions 35 x 147 x 129 mm (W/H/D). Accepts up to four communication modules (CM/CP) for PROFIBUS, PROFINET, or additional Ethernet interfaces. Operating temperature spans -40 to 70°C; below 0°C the display may be slower and dynamic content may have reduced legibility.
The CPU supports MRP as redundancy manager or client, with a maximum ring size of 50 devices. IRT ensures deterministic isochronous real-time communication for motion control. S7 routing enables data exchange with other Siemens controllers. DCP (Discovery and Configuration Protocol) is active for automatic PROFINET device setup. I²t protection of 0.02 A²·s limits short-circuit let-through energy on the backplane.
