Siemens 6ES7511-1FK02-0AB0 Programmable Logic Controller Module

Siemens 6ES7511-1FK02-0AB0 is a SIMATIC S7-1500F CPU 1511F-1 PN central processing unit designed for fail-safe automation with an integrated PROFINET IRT interface and a two-port switch. It provides 225 KB of program memory and 1 MB of data memory to support compact, safety-certified control logic and data handling. The processor delivers 60 ns bit performance for fast I/O update times and network operations, making it suitable for demanding real-time applications. A SIMATIC Memory Card is required to store the program and data; compatible memory card options include V16 (firmware v2.8) or V15 (firmware v2.5) or newer versions, aligning with modern engineering environments. The device is cataloged as a spare part in Siemens’ Industry Mall and is commonly deployed in spare-part scenarios or new installations within the S7-1500F family, where fail-safe operation is required and PROFINET IRT networking is used for deterministic communication. The product’s successor is 6ES7511-1FL03-0AB0, which Siemens lists as the newer 1511F-series spare part for maintenance and continuity.
